Pulmonary arteriovenous malformations (PAVMs) can be asymptomatic or result in a range of complications such as brain abscesses or cryptogenic emboli, which can contribute to morbidity and mortality if not diagnosed and treated in a timely manner. To date, there have been several reports of delayed diagnosis of PAVMs, which have been largely attributed to the misconception that PAVMs are too rare to be of clinical significance. Furthermore, because intracardiac shunting secondary to a patent foramen ovale (PFO) or atrial septal defect (ASD) also results in a positive saline contrast study with echocardiography, PAVM can be easily misdiagnosed as an intracardiac right-toleft shunt. However, there are unique echocardiographic features that differentiate between intracardiac shunting due to a PFO or ASD and extracardiac shunting such as in PAVM. This case details the course of a patient with recurrent cryptogenic strokes that was initially misattributed to a PFO and was only correctly diagnosed with multiple PAVMs after two failed attempts at PFO closure. This case serves as a reminder of an alternative etiology of right-to-left shunt and its presentation on imaging, which echocardiographers must be familiar with.

Objective: Lumbar puncture (LP) is performed by specialists in different branches of medicine, complications may be encountered in various settings. In our study, we evaluated the awareness and knowledge of the diagnosis and treatment of post-dural puncture headache (PDPH) among specialists who performed LP and/or encountered complications.

Methods: This was a prospective questionnaire/scale study of 253 physicians: LP performers (anaesthesiologists, Group A; others, Group B) and those who worked in departments that did not perform LP but frequently encountered complications following LP (Group C). The questionnaire assessed specialization, frequency of LPs utilization, needle types used, positions employed, awareness of LP complications, diagnosis, management, and risk factors for PDPH.

Results: Group A had the highest percentage of physicians who stated they had knowledge about PDPH (Group A: 96.4%, Group B: 77.3%, Group C: 39.4%; P=0.000). Group C was found to be statistically less informed than the other two groups (P=0.000). It was determined that only one (1%) physician from Group C correctly answered the question about the diagnostic criteria for PDPH.

Conclusion: To our knowledge this is the first study in which the awareness of PDPH has been compared according to physicians' fields of specialisation. We believe that post-specialty training programs should be organized for physicians who will either perform LP or monitor patients who have undergone LP, and the curriculum content in relevant specialties should be reviewed.

Objective: This study aimed to evaluate respiratory parameters during percutaneous internal ring suturing (PIRS) for inguinal hernia repair in two different-aged pediatric patients in whom the airway is provided with a laryngeal mask or endotracheal tube for general anaesthesia.

Methods: After local ethics committee and parental consent, 180 ASAI-II children were randomly allocated to 4 groups; according to their age (0-24 months / 25-144 months) and airway device laryngeal mask (LMA) / endotracheal tube (ETT) used for general anaesthesia (45 children each) for laparoscopic inguinal hernia repair. Standard anaesthesia induction was done with lidocaine, propofol, and fentanyl, and 0.6 mg kg^-1 rocuronium was added to the ETT groups. Sevoflurane is used for maintenance. Hemodynamic parameters, peak airway pressure, end-tidal carbon dioxide (EtCO₂), and peripheric oxygen saturation (SpO₂) values were recorded after induction, before, and during pneumoperitoneum. The duration of anaesthesia, surgery, recovery time, and surgical satisfaction was recorded. Airway complications (cough, laryngospasm, bronchospasm, desaturation, and aspiration) were recorded.

Results: Hundred and eighty patients (45 in each group) were analyzed. Duration of surgery and surgical satisfaction were similar in all groups. Duration of anaesthesia and recovery times were significantly shorter in the LMA groups. Peak airway pressure and EtCO2 levels were significantly lower in the LMA groups. Rare airway complications were observed without significance.

Conclusion: In laparoscopic inguinal hernia repair with the PIRS technique, LMA offered comparable operating conditions and surgical satisfaction.

Objective: Telemedicine has widely expanded during the coronavirus disease-2019 pandemic. Our objective was to evaluate the feasibility, safety, effectiveness, and satisfaction of pre-anaesthesia telephone consultation (PATC).

Methods: From December 2015 to October 2016, a prospective survey was administered to anaesthesiologists, nurse anaesthetists, and patients of the ambulatory and maxillofacial departments. Patients having a pre-anaesthesia consultation (PAC) within the previous year in the department, whose health state was considered stable, and for whom the surgical procedure was related to the previous one, were eligible for PATC. Three questionnaires concerning the pre- (Q1), per- (Q2), and postoperative (Q3) periods were answered by the patient, the anaesthesiologist, and the anaesthesiologist nurse to evaluate the feasibility and satisfaction of the PATC. We collected the cancelation rate and any incident occurring during the surgery.

Results: Over the study period, 210 patients were included. The response rate was 200/210 (95.2%) for Q1, 108/208 (51.9%) for Q2 and 146/208 (70.2%) for Q3. PATC was performed in a median (IQR) of 13 (7-20) days before the procedure. Patients answered directly in 73% of cases without the need for recall. During surgery, 4 incidents occurred and none were attributable to PATC. Patient satisfaction was 93.3% and 85.8% of them preferred PATC to conventional PAC. The kilometric saving was 74 (30-196) km per PATC.

Conclusion: Both patients and professionals were satisfied with PATC, which did not impact safety. On the selected patients, PATC brings many practical benefits and increases organizational flexibility.

Objective: Postoperative shivering (POS) is considered one of the most common complications that is encountered by the anaesthetists worldwide. Despite using several treatment options, there has not been a clear consensus regarding this issue. This trial was conducted to investigate the efficacy and safety of paracetamol and ondansetron in preventing POS in patients undergoing liposuction procedures under combined general epidural anaesthesia.

Methods: One hundred twenty patients scheduled for liposuction were randomly allocated to one of three groups: group P (paracetamol group) which received 1 g paracetamol intravenously, group O (ondansetron group) which received 8 mg of ondansetron intravenously, and group S (saline group), which received 100 mL normal saline intravenously; all medications were given postoperatively. The primary outcome was the incidence of POS, and the secondary outcomes included shivering score, tympanic temperature, and the occurrence of side effects.

Results: The incidence of occurrence of POS was found to be lower in groups P and O compared to group S with values of 25% and 37.50% vs. 77.50%, respectively, with a P value <0.001. Additionally, the severity of POS was found to be lower in groups P and O compared to group S (P <0.001). Tympanic temperature and complications were comparable between the groups with no significant differences.

Conclusion: Prophylactic use of paracetamol or ondansetron at the end of the procedure was shown to be of great value in reducing the incidence and severity of POS, with no statistically significant difference between the paracetamol and ondansetron groups. Moreover, no significant drawbacks were reported as a result of using these medications.

Objective: Percutaneous nephrolithotomy (PCNL) is accompanied by somatic and visceral pain intraoperatively and postoperatively. However, pain management strategies lack a decisive consensus. Erector spinae plane block (ESPB) is a novel paraspinal fascial block that can be used in PCNL patients, and we aimed to investigate whether ESPB will reduce intraoperative and postoperative opioid consumption and postoperative pain scores in PCNL patients.

Methods: The study was randomized, controlled, and open-label. Two groups were formed as the control group (GCont) and block group (Gblock), and patients received total intravenous anaesthesia. GBlock received an ESPB catheter in addition in the prone position. Intraoperative parameters and infusion doses, postoperative rescue analgesic doses, and pain scores were recorded. The primary endpoint was intraoperative analgesic consumption, and the secondary endpoints were postoperative pain scores and analgesic consumption.

Results: Sixty-four patients were analyzed. Remifentanil consumption of GCont was found to be significantly higher (GBlock: 0.0865 ± 0.030 vs GCont: 0.1398 ± 0.034, μg kg^-1 min^-1, P < 0.001). The control group reported higher pain scores between the 30^th min and 24^th hours and needed more analgesics between the 1^st and 6^th hours postoperatively. GBlock received local anaesthetics via ESPB catheter before nephrostomy tube removal and fewer patients needed analgesics [5 patients (15.6%) vs. 28 patients (87.5%), P < 0.001]. GCont consumed more tramadol postoperatively (262.5 mg vs. 75 mg, P < 0.001).

Conclusion: We found that ESPB reduced intraoperative opioid consumption. It also reduced the need for rescue analgesia and postoperative pain scores during nephrostomy tube removal. We concluded that the ESPB catheter may effectively be used in analgesia management during and after PCNL operations.

Fryns syndrome cases with variable characteristics require careful preoperative evaluation and have challenges for airway management. Craniofacial anomalies can complicate both ventilation and intubation. Extubation can also be problematic because of limited pulmonary reserves.

Objective: CD-8 T-cells are responsible for the clearance of virally infected cells. In patients with Coronavirus disease-2019 (COVID-19) pneumonia, there are quantitative reductions and functional impairments in T-cells. Low CD-8 T-cell levels cause worse clinical situations. In this study, the relationship between decreased CD-8 T-cells and mortality in patients with COVID-19 pneumonia in the intensive care unit (ICU) was investigated.

Methods: In this multicenter retrospective study, 277 patients were analyzed. Demographic data, ICU admission scores, blood gas levels, laboratory samples, and outcomes were recorded. Statistical Package for the Social Sciences version 28 was used for statistical analysis.

Results: Two hundred forty of 277 patients were included in the study. The mortality rate was 43.3%. In non-survivors, median values of age, Charlson comorbidity index, Acute Physiology and Chronic Health Evaluation II (APACHE-II), procalcitonin, leukocyte count, neutrophil count, neutrophil-lymphocyte count ratio, and duration of invasive mechanical ventilation were significantly higher, whereas median values of PaO₂-FiO₂ ratio, lymphocyte count, CD-4, and CD-8 T-cells were significantly lower than those in survivors. In the multivariate Cox regression model, the risk of mortality increased 1.04-fold (1.02-1.06) and 1.05-fold (1.01-10.8) by every one unit increase in age and APACHE-II, respectively, whereas it decreased 0.71-fold (0.58-0.87) by every hundred increase in CD-8 T-cells P < 0.001, P=0.007 and P=0.001 respectively.

Conclusion: According to our findings, age, APACHE-II, and CD-8 T-cell levels seem to be independent risk factors for mortality in patients with COVID-19 pneumonia in the ICU.

Aneurysmal subarachnoid hemorrhage (aSAH) is an emergency that needs prompt diagnosis and treatment with endovascular coiling or surgical clipping of the aneurysm to prevent re-bleeding. In addition to neurologic manifestations, aSAH can cause respiratory and cardiovascular complications. The prevention of hypoxemia and hypercarbia, control of intracranial pressure, and restoration of cerebral perfusion pressure should be the primary aims of early management. Secondarily, the most important causes of persistent neurological deficits and physical dependence in aSAH are vasospasm and delayed ischemia following bleeding. During that period, a focus on the detection, prevention, and treatment of vasospasm should be the rule. Transcranial Doppler allows detection and follow-up of vasospasm, especially in severe cases. Nimodipine is the only drug that has proven efficacy for treating vasospasm. Balloon angioplasty is performed in cases of resistance to medical treatment. Along with angioplasty, intra-arterial vasodilators can be administered. New diagnostic and therapeutic advances will hopefully improve outcomes in the near future.

A 61-year-old male patient diagnosed with Coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) was managed with tracheostomy and intermittent prone positioning in the intensive care unit. After a sudden deterioration, examination of tracheostomy tube (TT) and X-ray of the chest revealed that he had aspirated the fractured TT. The fractured tube was removed through the tracheostomy stoma using a rigid ventilating bronchoscope and forceps. Prone positioning is a beneficial postural therapy capable of improving patient oxygenation. However, it has some complications, like unplanned extubation and facial tissue injury. Percutaneous tracheostomy is also a valuable and safe procedure and has been increasingly performed in critical care patients, including those who suffer from COVID-19 ARDS. Fractures and aspiration of a tracheostomy tube can occur anytime after tracheostomy. We think prone positioning may contribute to the rupture and aspiration of the tracheostomy tube in this study.
