One proposed morphine alternative is hydromorphone. Studies investigating its use in post-cesarean analgesia are limited. This study was conducted to determine the median effective dose of intrathecal hydromorphone 12h postpartum.\u0000\u0000\u0000METHODS\u0000Twenty healthy women undergoing elective cesarean delivery were recruited into this study. Hydromorphone doses were determined using the up-down sequential method. The study dose of hydromorphone started at 6μg and was raised or lowered by 2μg depending on the 12-h efficacy of the preceding participant's dose. Pain scores of <3/10 were considered successful and the subsequent patient received a lower dose. Participants received 0.5% bupivacaine 12.5mg, fentanyl 25μg, and the study dose of hydromorphone as a single intrathecal injection.\u0000\u0000\u0000RESULTS\u0000Ten of 20 participants reported an effective hydromorphone dosage 12h post-injection. The median effective hydromorphone dosage was 4.6μg (95% CI 3.72 to 5.48μg) based on participants' reported visual analog pain scores of <3/10. No significant side effects or adverse outcomes were observed.\u0000\u0000\u0000CONCLUSION\u0000Intrathecal hydromorphone may be an effective alternative to morphine for post-cesarean pain management. The amount of intrathecal hydromorphone necessary to provide analgesia at 12h postoperatively may be significantly lower than doses currently in use. Further research should be performed to identify the optimal dose of intrathecal hydromorphone for post-surgical pain relief.","PeriodicalId":22104,"journal":{"name":"Survey of Anesthesiology","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74493161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the rate of difficulty has not been significantly reduced. With the modern technological advancements, devices such as video laryngoscopes, fiberoptic bronchoscopes, supraglottic airways (as a conduit for tracheal intubation), lighted stylets, and optical stylets offer alternate options.

In this issue of ANestHesIology, Bulka et al.6 provide an important addition to the small list of studies that attempt to examine the long-term consequences of PRNB. They report two main findings: (1) the use of neuromuscular blocking agents (NMBAs) was associated with a higher absolute rate of postoperative pneumonia (PoP) when compared to matched cases where patients did not receive relaxants and (2) failure to reverse NMBAs at the end of surgery was associated with a 2.25-fold increase in the incidence of PoP. Why should these findings be less than surprising? Bulka et al.6 noted that the incidence rate ratio (1.79) for PoP was significantly higher in patients who received NMBAs. This observation is consistent with the findings from several large database investigations, which have described an association between intraoperative NMBA use and major morbidity and mortality. More than 60 yr ago, Beecher and todd7 reported that the risk of death related to anesthesia was six times higher in patients receiving NMBAs compared to those administered no muscle relaxants. An analysis of data collected over a 10-yr period (1967 to 1976) involving 240,483 anesthetics revealed that “respiratory inadequacy after myoneural blockade” was the second most common cause of death after surgery.8 similarly, a study from great Britain reported that postoperative respiratory failure secondary to dosing of NMBAs was a primary cause of mortality.9 In a large prospective study, the use of the long-acting NMBA pancuronium entailed a higher risk of postoperative pulmonary complications.10 More recent studies reported that patients administered NMBAs had a higher risk of postoperative desaturations and need for reintubation11 and that those given high doses of NMBAs had an increased risk of postoperative respiratory complications.12 The increased incidence of morbidity and mortality reported in patients administered NMBAs is likely secondary to PRNB. Incomplete neuromuscular recovery during a vulnerable postoperative period (between tracheal extubation and achieving a train-of-four [toF] ratio of less than 0.9 in the PACU) may impair upper airway patency, protective airway reflexes, breathing, swallowing, and coughing, resulting in an increased risk of significant respiratory events (like PoP) and death.

Especially in cases dealing with childbirth, where substantial blood loss can occur, having an efficient and effective plan and line of communication between the parturient and her caregivers is crucial to ensure the most beneficial outcome for the patient while respecting her constitutionally protected right to make an informed choice about her medical treatment. The authors of this article reviewed concepts and care options as they related to the perioperative care of a Jehovah's Witness parturient. Courts have upheld that competent pregnant women have the right of bodily self-determination and therefore can refuse blood transfusion. This article established the importance of having a patient's care preferences and directives clearly expressed. For example, patients may do this in writing by using an advance health care directive, which would clearly delineate their personal decisions not only on blood transfusion but also in regard to derivatives of plasma or cellular blood components and autologous blood management, which are “conscience” items on which Witnessesmake individual decisions. Although patients have the right to decline treatments, the physician also has a duty to disclose any risks associated with refusing a treatment and to educate patients on alternative treatments. Communication between parturients and their medical caregivers is key throughout the entire treatment process. This article suggests using a perioperative surgical home model to coordinate care throughout the entire surgical experience as this model is fitting for the unique needs of the Jehovah's Witness population. The use of pharmacologic therapies is also recommended when alternatives to blood transfusion are needed. The authors of this article also suggest several options for reducing perioperative transfusion requirements and medical options for Jehovah's Witness patients who experience a massive hemorrhage. Blood conservation techniques should be considered as Jehovah's Witnesses have differing opinions about what treatments are allowed. Although some Jehovah's Witness parturients may consent to the use of acute normovolemic hemodilution and blood cell salvage, other Witnesses may have stricter specifications. Anesthetic and surgical techniques should be executed in a way that decreases blood loss. Again, the authors emphasize communication between patients and caregivers to expedite any necessary interventions in the threat or event of hemorrhage. The care of a Jehovah's Witness parturient must encompass all medical, ethical, and legal considerations.

The flow-dependent resistance of the DLT's bronchial limb may be high as a result of its narrow inner diameter and length, and thus potentially contribute to an unintended increase in positive end-expiratory pressure (auto-PEEP). We therefore studied the impact of adult sized DLTs on the dynamic auto-PEEP during OLV.\u0000\u0000\u0000METHODS\u0000In this prospective clinical study, dynamic auto-PEEP was determined in 72 patients undergoing thoracic surgery, with right- and left-sided DLTs of various sizes. During OLV, air trapping was provoked by increasing inspiration to expiration ratio from 1:2 to 2:1 (five steps). Based on measured flow rate, airway pressure (Paw) and bronchial pressure (Pbronch), the pressure gradient across the DLT (ΔPDLT) and the total auto-PEEP in the respiratory system (i.e. the lungs, the DLT and the ventilator circuit) were determined. Subsequently the DLT's share in total auto-PEEP was calculated.\u0000\u0000\u0000RESULTS\u0000ΔPDLT was 2.3 (0.7) cm H2O over the entire breathing cycle. At the shortest expiratory time the mean total auto-PEEP was 2.9 (1.5) cm H2O (range 0-5.9 cm H2O). The DLT caused 27 to 31% of the total auto-PEEP.
