Objective

To evaluate the diagnostic accuracy of sidestream and mainstream capnography to detect misplacement of small-bore, styleted nasoenteric (NE) feeding tubes into the respiratory tract of dogs and cats.

Design

Prospective study from February 2020 to November 2020.

Setting

University teaching hospital.

Animals

Ten dogs and 10 cats undergoing elective surgical procedures.

Interventions

Under general anesthesia, an NE feeding tube attached to a handheld sidestream (dogs and cats) then mainstream capnograph (dogs) was inserted into the patient's endotracheal (ET) tube. Respiratory rate, end-tidal carbon dioxide (ETCO₂), and time to ETCO₂ waveform were recorded.

Measurements and Main Results

Mainstream capnography failed to detect an ETCO₂ reading or respiratory waveform in all dogs evaluated. In dogs and cats, sidestream capnography accurately detected ETCO₂ measurement, respiratory rate, and waveform within 4 s of feeding tube insertion into the ET tube, with ETCO₂ readings >35 mm Hg in all dogs and >20 mm Hg in all cats. ETCO₂ readings obtained from the NE tubes were similar to but did not match those obtained by the anesthesia monitoring equipment for dogs and cats. Sidestream capnography accurately detects airway intubation with small-bore, styleted NE tubes in dogs and cats, regardless of patient size. Further studies are required to determine whether this method could be used in awake and sedated patients in real time to detect airway intubation during placement of NE tubes.

Conclusions

Sidestream capnography is able to detect misplacement of small-bore, styleted feeding tubes into the respiratory tract of dogs and cats regardless of patient size. This technique shows promise as a tool to reduce respiratory complications of feeding tube placement in veterinary patients.

目的：评价侧流造影和主流造影对犬猫呼吸道小口径、样式鼻肠（NE）饲管错位的诊断准确性。设计：2020年2月至2020年11月的前瞻性研究。单位：大学教学医院。动物：10只狗和10只猫正在接受选择性手术。干预措施：在全身麻醉下，将NE喂食管连接到手持侧流（狗和猫），然后将主流二氧化碳记录仪（狗）插入患者的气管内（ET）管。记录呼吸频率、潮末二氧化碳（ETCO2）及到ETCO2的时间波形。测量结果和主要结果：在所有评估的狗中，主流毛细管造影未能检测到ETCO2读数或呼吸波形。在狗和猫中，侧流造影准确地检测了饲管插入ET管后4 s内的ETCO2测量值、呼吸速率和波形，所有狗的ETCO2读数>为35 mm Hg，所有猫的ETCO2读数>为20 mm Hg。从NE管获得的ETCO2读数与狗和猫的麻醉监测设备获得的读数相似，但不匹配。侧流造影可以准确地检测狗和猫的气管插管，无论病人的大小。该方法是否可用于清醒和镇静患者在放置NE管时实时检测气道插管，尚需进一步研究。结论：侧流造影能够检测到小口径的、有样式的饲管进入狗和猫的呼吸道，而不管病人的大小。该技术有望作为一种工具来减少兽医患者喂食管放置的呼吸并发症。

Objective

To describe and discuss the unusual clinical presentation, novel imaging findings, and management of a cat with pituitary apoplexy and associated intraventricular hemorrhage.

Case Summary

A 13-year-old neutered male domestic shorthair cat presented with semi-comatose mentation and marked polyuria. The menace response and pupillary light and vestibuloocular reflexes were absent, while the corneal reflex was maintained. The cat also had sinus bradycardia, hypoventilation, and hypothermia, indicating a multifocal brain lesion. The urine was hyposthenuric (urine specific gravity 1.003), and with increasing hypernatremia, central diabetes insipidus was suspected. After approximately 2 h in the hospital, there was mild improvement in neurological deficits and vital parameters. Computed tomography revealed a pituitary tumor with intralesional and extensive extralesional parenchymal and intraventricular hemorrhage. The cat was euthanized at the owner's request due to the uncertainty of treatment duration and outcome.

New or Unique Information Provided

This is the first reported case of suspected central diabetes insipidus in a dog or cat with PA and intraventricular hemorrhage; novel clinical and imaging findings are presented.

Delayed Zinc Phosphide Toxicosis in a Dog 犬迟发性磷化锌中毒。

IF 1.2 3区农林科学 Q3 VETERINARY SCIENCES

Journal of veterinary emergency and critical care

Pub Date : 2025-06-25 DOI: 10.1111/vec.13478

Objective

Zinc phosphide is a widely used, commercial, non-anticoagulant rodenticide. However, there is a lack of detailed information in veterinary literature regarding its toxic effects. The purpose of this case report is to provide a comprehensive description of toxicosis caused by zinc phosphide in a dog that underwent early decontamination.

Case Summary

A 5-year-old neutered male Wolfhound mix presented 4 h after ingesting zinc phosphide. The owners had attempted decontamination by giving the dog one tablespoon of table salt orally before arrival. On initial examination, the dog showed injected mucous membranes and apparent abdominal pain. Mild hyperlactatemia (2.3 mmol/L) was documented. Initial treatment included IV administration of maropitant (1 mg/kg), esomeprazole (1 mg/kg), and compound sodium lactate (6 mL/kg/h). Fourteen hours after toxin ingestion, a generalized seizure occurred, which was controlled with diazepam (0.5 mg/kg IV). Hypoglycemia was identified and treated with a glucose bolus and continuous infusion. Metabolic acidosis was treated with sodium bicarbonate, and despite this treatment, metabolic acidosis persisted and hyperlactatemia worsened to 8.0 mmol/L. Acute hepatic failure was presumptively diagnosed based on increased prothrombin time, excessive bleeding from a lip laceration, hypoglycemia, and severely increased alanine aminotransferase activity and total bilirubin concentration. Treatment with vitamin K and N-acetylcysteine was initiated. Hypotension, which did not respond to a conservative fluid bolus, in combination with acute hepatic failure, prompted the cost-conscious owners to elect humane euthanasia.

New or Unique information Provided

This is the first report detailing a confirmed case of zinc phosphide toxidrome and acute liver failure in a dog. A retrospective study of potential exposures suggested good outcomes; however, this report demonstrates that even when signs appear limited to the gastrointestinal tract at presentation, ingestion of zinc phosphide should be aggressively monitored and treated.

目的：磷化锌是一种应用广泛的商业非抗凝血灭鼠剂。然而，在兽医文献中缺乏关于其毒性作用的详细信息。本病例报告的目的是提供一个全面的描述由磷化锌引起的中毒在狗接受早期净化。病例总结：一只5岁的绝育公狼犬在摄入磷化锌4小时后出现。主人曾试图在到达之前给狗口服一汤匙食盐来消毒。在最初的检查中，狗显示注射粘膜和明显的腹痛。轻度高乳酸血症（2.3 mmol/L）。初始治疗包括静脉给予马洛匹坦（1mg /kg）、埃索美拉唑（1mg /kg）和复方乳酸钠（6ml /kg/h）。摄入毒素14小时后发生全面性癫痫发作，用地西泮（0.5 mg/kg IV）控制。发现低血糖并给予葡萄糖丸和持续输注治疗。用碳酸氢钠治疗代谢性酸中毒，尽管进行了治疗，代谢性酸中毒仍持续存在，高乳酸血症恶化至8.0 mmol/L。根据凝血酶原时间增加，唇裂出血过多，低血糖，谷丙转氨酶活性和总胆红素浓度严重升高，推定急性肝功能衰竭。开始用维生素K和n -乙酰半胱氨酸治疗。保守的输液对低血压无效，再加上急性肝功能衰竭，这促使有成本意识的主人选择人道安乐死。提供新的或独特的信息：这是第一个详细报道了一只狗的磷化锌中毒和急性肝衰竭的确诊病例。一项潜在暴露的回顾性研究显示结果良好；然而，本报告表明，即使症状出现仅限于胃肠道，摄入磷化锌也应积极监测和治疗。

Objective

To describe therapeutic plasma exchange as treatment for severe acute hemolytic anemia following human intravenous immunoglobulin (hIVIG) in a dog with primary immune-mediated thrombocytopenia (IMTP).

Case Summary

A 4-year-old neutered female Pomeranian with a recent diagnosis of IMTP presented with a potential relapse. Management with initial medications, including prednisolone and mycophenolate mofetil, was unsuccessful; therefore, the dog was administered hIVIG. Fifteen hours later, the patient developed an adverse reaction including vomiting and dark urine. Laboratory and clinical evidence of acute hemolysis was detected, including decreased hematocrit, hemoglobinemia from gross identification of serum, elevated total bilirubin, hemoglobinuria, and reticulocytosis. Supportive care for the dog was ineffective, and due to an adverse reaction characterized by severe salivation, a blood transfusion could not be done. Therapeutic plasma exchange (TPE) was performed to eliminate the causative agents, controlling the hemolytic anemia. After TPE, immunosuppressants were prescribed to treat the IMTP, which resolved 15 days later. At the time of this report, the patient is alive with no complications or clinical signs of IMTP.

Unique Information Provided

Acute hemolytic anemia associated with hIVIG is a rare adverse reaction in veterinary medicine. This is the first report of TPE being used to successfully treat this potentially life-threatening condition.

目的：探讨血浆置换治疗犬原发性免疫介导性血小板减少症（IMTP）患者因人静脉注射免疫球蛋白（hIVIG）引起的严重急性溶血性贫血。病例总结：一名4岁的绝育雌性博美犬，最近诊断为IMTP，并表现出潜在的复发。最初的药物治疗，包括强的松龙和霉酚酸酯，没有成功；因此，这只狗被注射了hiv。15小时后，患者出现呕吐、尿色深等不良反应。检测到急性溶血的实验室和临床证据，包括红细胞压积下降，血清总体鉴定血红蛋白血症，总胆红素升高，血红蛋白尿和网状红细胞增多症。对狗的支持性护理无效，由于严重的唾液分泌不良反应，无法进行输血。治疗性血浆置换（TPE）可消除致病菌，控制溶血性贫血。TPE后，给予免疫抑制剂治疗IMTP， 15天后消退。在本报告时，患者存活，无并发症或IMTP的临床体征。提供的独特信息：由hIVIG引起的急性溶血性贫血在兽医学中是一种罕见的不良反应。这是首次报道TPE被成功用于治疗这种可能危及生命的疾病。

Objective

To assess factors associated with return of spontaneous circulation (ROSC), sustained ROSC, and survival to discharge in patients undergoing CPR and to identify poor prognostic indicators to guide decisions and timing for the termination of resuscitative efforts.

Design

International, multi-institutional veterinary CPR registry data report.

Setting

Sixteen veterinary private practice and university teaching hospitals in the United States, Europe, and Australia.

Animals

Data from 354 dogs and 138 cats with in-hospital arrest undergoing CPR that were entered into the Reassessment Campaign on Veterinary Resuscitation CPR registry between February 2016 and December 2021.

Interventions

None.

Measurements and Main Results

One hundred thirty-two dogs (37.3%) and 56 cats (40.6%) with in-hospital cardiopulmonary arrest achieved ROSC, of which 63 dogs (17.8%) and 28 cats (20.3%) had sustained ROSC (lasting >20 min), with 14 dogs (4.0%) and four cats (2.9%) surviving to hospital discharge. Maximum end-tidal partial pressure of carbon dioxide (ETCO₂) of ≥15 mm Hg was associated with ROSC in cats and dogs in univariate models, ROSC in both species in a multivariate model, and sustained ROSC in dogs in univariate and multivariate models. In dogs, the odds of both sustained ROSC and survival to discharge decreased with every additional minute of CPR, and CPR delivered for ≤10 min was associated with higher odds of both ROSC and sustained ROSC in the univariate model. In both dogs and cats, the odds of achieving ROSC were higher in patients initially identified with bradycardia rather than asystole. ROSC and survival to discharge were associated with anesthetic arrests in dogs and peri-anesthetic arrests in both cats and dogs.

Conclusions

This study found several factors associated with ROSC that might help guide clinicians’ efforts during CPR and emphasized the importance of monitoring ETCO₂. Many questions remain that will need further study.

目的：评估心肺复苏术患者自发循环恢复（ROSC）、持续ROSC和存活至出院的相关因素，并确定不良预后指标，以指导决定和终止复苏的时机。设计：国际、多机构兽医CPR登记数据报告。环境：在美国、欧洲和澳大利亚有16家兽医私人诊所和大学教学医院。动物：来自354只狗和138只猫的数据，这些狗和猫在2016年2月至2021年12月期间接受了心肺复苏术，并进入了兽医复苏心肺复苏术重新评估运动登记处。干预措施:没有。测量和主要结果：院内心肺骤停犬132只（37.3%）、猫56只（40.6%）达到ROSC，其中63只（17.8%）、28只（20.3%）持续ROSC（持续20分钟），存活至出院犬14只（4.0%）、猫4只（2.9%）。在单变量模型中，最大潮末二氧化碳分压(ETCO2)≥15 mm Hg与猫和狗的ROSC相关，在多变量模型中，这两个物种的ROSC都与此相关，在单变量和多变量模型中，狗的持续ROSC也与此相关。在狗中，持续ROSC和存活到出院的几率随着CPR每增加一分钟而降低，在单变量模型中，CPR时间≤10分钟与ROSC和持续ROSC的几率较高相关。在狗和猫中，最初诊断为心动过缓而不是心脏骤停的患者获得ROSC的几率更高。ROSC和存活到出院与狗的麻醉停搏和猫和狗的麻醉停搏有关。结论：本研究发现了与ROSC相关的几个因素，这些因素可能有助于指导临床医生在心肺复苏术期间的工作，并强调了监测ETCO2的重要性。还有许多问题需要进一步研究。

Objective

To assess for ECG changes, particularly affecting the QT interval, in healthy dogs administered maropitant and to compare methods of QT interval correction in dogs.

Design

Prospective interventional pre–post study.

Setting

University teaching hospital.

Animals

Twenty-seven healthy, privately owned dogs.

Interventions

After physical examination, bloodwork, and baseline six-lead ECG, dogs were administered a standard antiemetic dose of maropitant (1 mg/kg, SC). A follow-up ECG was performed 35–65 min later, after maximum plasma concentration was expected to be reached.

Measurements and Main Results

Twenty dogs completed the study. No adverse effects of maropitant were witnessed apart from apparent pain on injection, and no tachyarrhythmias or bradyarrhythmias were observed. ECG measurements included RR interval, QT interval, TQ interval, PR interval, P wave duration and amplitude, and QRS complex duration and amplitude. Instantaneous heart rate (HR) was determined based on the RR interval, followed by HR correction of QRS complex duration and QT interval using the Rautaharju, Van de Water, and Hodges formulas. Cardiac restitution was also evaluated using the QT/TQ ratio. Comparisons made before and after maropitant administration showed subtle prolongation of the QTc that only reached significance with the Van de Water formula and no change in the QT/TQ ratio. A significant reduction in P wave amplitude was observed with maropitant. An increase in variability between formulas at higher HRs was seen when QT interval correction formulas across a range of HRs were compared.

Conclusions

Maropitant administered subcutaneously at a standard antiemetic dose may induce a slight prolongation of the QTc and a reduction in P wave amplitude that are unlikely to promote tachyarrhythmias such as torsades de pointes or become clinically relevant in healthy dogs. The Van de Water formula may be more accurate across a wide range of HRs in dogs than the Rautaharju and Hodges formulas.

目的：评价使用马洛匹坦的健康犬的心电图变化，特别是对QT间期的影响，并比较QT间期矫正方法。设计：前瞻性介入前后研究。单位：大学教学医院。动物：27只健康的私人养狗。干预措施：在身体检查、血液检查和基线六导联心电图后，给狗服用标准止吐剂量的马洛匹坦（1mg /kg， SC）。在预计达到最大血药浓度后，随访心电图35-65分钟。测量和主要结果：20只狗完成了研究。除注射时明显疼痛外，未观察到马洛匹坦的不良反应，未观察到快速性心律失常或慢速性心律失常。心电图测量包括RR间期、QT间期、TQ间期、PR间期、P波持续时间和幅值、QRS复合持续时间和幅值。根据RR间期测定瞬时心率（HR），然后使用Rautaharju、Van de Water和Hodges公式对QRS复合持续时间和QT间期进行HR校正。心脏恢复也用QT/TQ比值进行评估。马洛匹坦给药前后的比较显示，QTc有轻微延长，只有Van de Water公式才有意义，QT/TQ比没有变化。马洛匹坦可显著降低P波振幅。当比较不同hr范围内的QT间期校正公式时，可以看到较高hr时公式之间的变异性增加。结论：标准止吐剂量的马洛匹坦皮下给药可能会导致QTc的轻微延长和P波振幅的降低，这些不太可能促进速性心律失常，如点扭转或在健康犬中具有临床相关性。Van de Water公式可能比Rautaharju和Hodges公式在狗的大范围hr中更准确。

Objective

To document the effects of epsilon aminocaproic acid (εACA) as a continuous rate infusion on the need for blood products and change in PCV during the perioperative period in dogs with spontaneous hemoperitoneum.

Design

Prospective, randomized, open-label controlled study.

Setting

Private practice specialty teaching hospital.

Animals

Eighteen client-owned dogs presenting with spontaneous hemoperitoneum.

Interventions

Dogs with a confirmed diagnosis of spontaneous hemoperitoneum secondary to an intraabdominal mass intended for surgical intervention were randomized to receive either εACA (50 mg/kg bolus, followed by a continuous rate infusion at 25 mg/kg/h for 24 h, n = 10) or standard therapy (n = 8).

Measurements and Main Results

PCV and total solids were obtained at presentation, preoperatively, immediately postoperatively, and at 24 h postoperatively. Six dogs, two in the control group and four in the εACA group, received blood transfusions (33%). There was no significant difference between the number of patients receiving transfusions in the control group compared with the εACA group (p = 1.0). The median volume of blood removed from the abdomen at the time of surgery and the difference in PCV and total solids at any time point were not significantly different between the treatment and control groups. Dogs taken to surgery sooner (surgery delay <265 min) had a significantly lower postoperative PCV compared with initial (p < 0.01) and preoperative blood samples (p = 0.047). There were no adverse events attributed to εACA in any patients.

Conclusions

Perioperative εACA was not associated with reduced requirement for blood product or blood loss at the time of surgery.

目的：观察epsilon氨基己酸（εACA）连续速率输注（CRI）对自发性腹膜出血犬围手术期血液制品需求及PCV变化的影响。设计：前瞻性、随机、开放标签对照研究。单位：私立执业专科教学医院。动物：18只客户拥有的狗出现自发性腹膜出血。干预措施：经确诊为腹内肿块继发自发性腹膜出血，拟进行手术干预的犬随机接受εACA （50 mg/kg，随后以25 mg/kg/h的剂量进行CRI，持续24小时，n = 10）或标准治疗（n = 8）。测量和主要结果：PCV和总固体量分别于术前、术后、即刻和术后24小时测量。6只狗接受输血，对照组2只，εACA组4只（33%）。对照组输血人数与εACA组比较，差异无统计学意义（P = 1.0）。治疗组与对照组手术时腹部中位取血量、各时间点PCV和总固体量的差异均无显著性差异。结论：围手术期εACA与手术时血制品需要量或出血量的减少无关。

Objective

To evaluate the amount of sleep obtained by hospitalized dogs and cats in an intensive care setting and to identify factors that may impact veterinary patients’ sleep.

Design

A prospective, observational study spanning a 4-week period in June of 2020.

Setting

Academic teaching hospital.

Animals

A total of 96 dogs and 16 cats hospitalized in the ICU during the 4-week study period.

Interventions

None.

Measurements and Main Results

Patient activity was categorized as active, resting, or asleep and was recorded along with ICU environmental data on an hourly basis. Environmental data consisted of subjective assessment of noise level, ambient lighting, number of people present, and number of hospitalized patients. The median observed time asleep was 40% and 11% for dogs and cats, respectively. During natural nighttime hours (9:00 p.m. to 6:00 a.m.), the odds of a patient being asleep were 1.7 times higher if lights were dimmed (p < 0.001). Patients were also less likely to be asleep with higher noise levels (odds ratio 0.66 for each increase in noise level, p = 0.003).

Conclusions

Hospitalized dogs and cats experience sleep disturbances similar to those reported in human ICU patients. Ambient noise and light are significant factors contributing to sleep disruption in cats and dogs hospitalized in a veterinary ICU. The findings of this study support implementing efforts to promote patient sleep through environmental modifications in the veterinary intensive care setting. Additional research is needed to establish objective means of assessing sleep in hospitalized dogs and cats, to determine sleep patterns of hospitalized veterinary patients, and to quantify the impact of sleep disturbances on veterinary patient convalescence.

Objective

To describe pneumothorax as a complication of nasogastric tube (NGT) misplacement in six dogs at a single institution and to discuss NGT placement techniques and pneumothorax prevention strategies found in the human and veterinary literature.

Design

Retrospective case series.

Setting

Private referral center.

Animals

Six client-owned dogs.

Measurements and Main Results

Medical records at a private practice referral hospital were searched for cats and dogs with “nasogastric tube” and “pneumothorax” from January 2013 to May 2022. Data collected from the medical records, where available, included patient signalment, weight, primary disease process, relevant diagnostic test results, clinical signs before NGT placement, size of NGT, personnel performing tube placement, sedation administered before NGT placement, therapies administered for management of pneumothorax, duration of hospitalization, and outcome. Six dogs were included, having developed pneumothorax secondary to NGT misplacement during the 9-year period (incidence = 0.0006). Four of the six dogs received IV sedation before NGT placement. Three of the six dogs displayed clinical signs of pneumothorax, including an abnormal breathing pattern and coughing. Thoracocentesis was required in three of the dogs, and one ultimately required a thoracostomy tube for 24 h. Pneumothorax fully resolved in all patients, and four survived to discharge. Two dogs were euthanized due to worsening clinical conditions unrelated to pneumothorax.

Conclusions

This retrospective study describes the complete resolution of iatrogenic pneumothorax in six dogs after NGT misplacement. Clinicians should be aware of the possibility of pneumothorax during NGT placement and warn clients of the risk. Fatalities have been reported secondary to this complication; however, due to lack of veterinary data, the survival rate is uncertain. Results of this case series indicate that the prognosis may be good for resolution of pneumothorax secondary to NGT misplacement with subsequent discharge from the hospital.

目的：介绍某医院6只狗因鼻胃管（NGT）错位引起的气胸并发症，并讨论人类和兽医文献中发现的NGT放置技术和气胸预防策略。设计：回顾性病例系列。设置：私人转诊中心。动物：6只客户养的狗。测量结果和主要结果：检索了2013年1月至2022年5月期间一家私人诊所转诊医院的医疗记录，其中有“鼻胃管”和“气胸”的猫和狗。从医疗记录中收集的数据（如有）包括患者信号、体重、原发疾病过程、相关诊断测试结果、NGT放置前的临床体征、NGT的大小、进行管放置的人员、NGT放置前的镇静、气胸治疗的治疗方法、住院时间和结果。6只犬在9年期间发生了继发于NGT错位的气胸（发病率= 0.0006）。6只狗中有4只在植入NGT前接受了静脉镇静。6只狗中有3只表现出气胸的临床症状，包括呼吸方式异常和咳嗽。其中3只狗需要胸腔穿刺术，1只最终需要开胸管24小时。所有患者的气胸完全消除，4只存活出院。两只狗因与气胸无关的临床状况恶化而被安乐死。结论：本回顾性研究描述了6只NGT错位后医源性气胸的完全解决。临床医生应该意识到NGT放置期间气胸的可能性，并提醒病人注意这一风险。据报道，该并发症导致死亡；然而，由于缺乏兽医数据，存活率是不确定的。本病例系列的结果表明，NGT错位继发气胸的预后可能是良好的，随后出院。

Data collected from the medical records, where available, included patient signalment, weight, primary disease process, relevant diagnostic test results, clinical signs before NGT placement, size of NGT, personnel performing tube placement, sedation administered before NGT placement, therapies administered for management of pneumothorax, duration of hospitalization, and outcome. Six dogs were included, having developed pneumothorax secondary to NGT misplacement during the 9-year period (incidence = 0.0006). Four of the six dogs received IV sedation before NGT placement. Three of the six dogs displayed clinical signs of pneumothorax, including an abnormal breathing pattern and coughing. Thoracocentesis was required in three of the dogs, and one ultimately required a thoracostomy tube for 24 h. Pneumothorax fully resolved in all patients, and four survived to discharge. Two dogs were euthanized due to worsening clinical conditions unrelated to pneumothorax.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>This retrospective study describes the complete resolution of iatrogenic pneumothorax in six dogs after NGT misplacement. Clinicians should be aware of the possibility of pneumothorax during NGT placement and warn clients of the risk. Fatalities have been reported secondary to this complication; however, due to lack of veterinary data, the survival rate is uncertain. Results of this case series indicate that the prognosis may be good for resolution of pneumothorax secondary to NGT misplacement with subsequent discharge from the hospital.</p>\u0000 </section>\u0000 </div>","PeriodicalId":17603,"journal":{"name":"Journal of veterinary emergency and critical care","volume":"35 3","pages":"274-278"},"PeriodicalIF":1.2,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144259516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
