5 ± 1.9 vs. 5.0 ± 0.0 cmH2O and T2, 12.4 ± 1.9 vs. 5.0 ± 0.0 cmH2O, both P less then 0.001). Partial pressures of oxygen decreased significantly from baseline during pneumoperitoneum in the control group but not in the intervention group. Nevertheless, the changes in partial pressures of oxygen did not differ between groups. Compliance of the respiratory system (CRS) significantly decreased and driving pressure significantly increased during pneumoperitoneum in both groups. However, the changes in CRS and driving pressure were significantly less in the intervention group. Transpulmonary pressure during expiration was maintained in the intervention group while it decreased significantly in the control group. NB 598 manufacturer CONCLUSION PEEP setting guided by Poeso measurement showed no beneficial effects in terms of oxygenation but respiratory mechanics were better during laparoscopic gynaecological surgery. TRIAL REGISTRATION ClinicalTrials.gov identifier NCT03256396.BACKGROUND The chronic use of opioids and glucocorticoids is associated with serious side effects. Moreover, both medications are related to poor long-term postoperative outcomes. OBJECTIVE The study aimed to investigate the association between pre-operative chronic opioid and glucocorticoid use and 90-day mortality after noncardiac surgery. DESIGN Retrospective, population-based cohort study. SETTING Single tertiary academic hospital. PATIENTS The study enrolled adult (≥18 years of age) patients admitted to Seoul National University Bundang Hospital, between January 2012 and December 2018 for planned, elective, noncardiac surgery. MAIN OUTCOME MEASURES The study compared the 90-day mortality for patients using opioids or glucocorticoids chronically (≥3 months) prior to surgery and for opioid-naïve and glucocorticoid-naïve patients. RESULTS A total of 112 606 patients were included in the study. Among them, 107 843 (95.9%) were opioid-naïve and glucocorticoid-naïve patients; 3373 (3.0%), 1199 (1.1%) and 191 patients (0.2%) were chronic users of opioids, glucocorticoids or both, respectively. In the multivariable model, compared with opioid-naïve and glucocorticoid-naïve patients, the odds of dying within 90 days were significantly higher for chronic users of opioids [3.56-fold; 95% confidence intervals (CIs) 2.36 to 5.38; P less then 0.001], glucocorticoids (4.17-fold; 95% CI 3.28 to 5.29; P less then 0.001) and combined opioids and glucocorticoids (7.66-fold; 95% CI 3.91 to 15.01; P less then 0.001). CONCLUSION Chronic pre-operative use of opioids and glucocorticoids, together or individually, were associated with increased 90-day mortalities after noncardiac surgery, compared with opioid-naïve and glucocorticoid-naïve patients. Our results suggest that chronic pre-operative use of opioids and glucocorticoids should be managed carefully.BACKGROUND Postoperative nausea and vomiting (PONV) is the most frequent side effect following anaesthesia. Predisposition to developing PONV is multifactorial with patient risk factors and anaesthetic techniques both being contributory. However, there is also a genetic susceptibility to PONV, and several studies have aimed to identify polymorphisms contributing to a genetic PONV risk. OBJECTIVE We summarised previous published studies investigating genetic contribution to PONV risk. DESIGN Systematic review without meta-analysis. DATA SOURCE We searched MEDLINE until June 2019. ELIGIBILITY CRITERIA Articles were chosen for review when PONV and polymorphisms were included. Exclusion criteria were reviews/meta-analysis/comments, articles not in the English language, nonappropriate content (e.g. PONV not as primary aim of the study, study investigated opioid-induced nausea) or if articles were pharmacogenetic studies addressing treatment of PONV. RESULTS A total of 59 studies were screened and 14 articles were urther high-quality studies are needed to reveal more insights in genetic PONV susceptibility, particularly so in non-Caucasian ethnicities.BACKGROUND Drug errors during neuraxial anaesthesia or analgesia are not well known. OBJECTIVES To review the clinical consequences associated with incorrect administration of neuromuscular blocking drugs (NMBDs) during spinal or epidural anaesthesia, and to investigate human factors and strategies available to help prevent such errors. DESIGN A review of reports of neuraxial administration of NMBDs in humans. DATA SOURCES Published reports of errors involving NMBDs. We searched the period between 1965 and 2019. ELIGIBILITY CRITERIA Error reports in any language. Nonneuraxial drug errors were excluded. RESULTS We identified 20 reports involving seven different NMBDs inadvertently administered via the epidural or intrathecal routes. All patients developed systemic neuromuscular junction blockade. Fourteen errors occurred while patients were awake. The onset of action was delayed following epidural rocuronium and suxamethonium. The duration of action was prolonged following epidural administration of vecuronium, pancuronium, cisatracrium and suxamethonium. Five patients required emergency airway interventions. Intrethecal gallamine caused convulsions and muscle spasms migrating up the body. Syringe swap was the primary cause for the majority of errors and perceptual errors were the most common. Implementation of recommendations could have prevented the errors. CONCLUSION Following the epidural injection of NMBDs the effects are delayed and prolonged. There was no serious morbidity reported following neuraxial administration of the NMBDs used in current practice. Perceptual errors resulting in incorrect syringe choice were the commonest cause. Four measures can be introduced to reduce such errors.BACKGROUND AND AIM Tenofovir disoproxil fumarate (TDF) and entecavir are effective antiviral medications that are recommended as first-line monotherapies for the treatment of chronic hepatitis B (CHB) infection, including decompensated liver cirrhosis with ascites. Acute kidney injury (AKI) commonly occurs in patients with cirrhosis and ascites. The aim of this study was to compare the development of AKI during TDF and entecavir treatment of CHB patients with cirrhotic refractory ascites. METHODS From January 2011 to April 2017, we identified patients who were diagnosed with cirrhosis with refractory ascites and received TDF or entecavir treatments at Kaohsiung Chang Gung Memorial Hospital. AKI was defined as an increase in serum creatinine of more than 0.3 mg/dL or 1.5-fold from baseline. All episodes of AKI were recorded and compared between those who received TDF and entecavir. RESULTS A total of 111 patients were enrolled in this retrospective study, of which 22 patients were treated with TDF and 89 were treated with entecavir.
