Objective and Subjective Evaluations of the Effects of Different Types of Intubation Tube Applications on Voice Performance in the Early Postoperative Period

IntroductionDespite the use of quantitative neuromuscular monitoring together with the administration of reversal drugs (neostigmine or sugammadex), the incidence of residual neuromuscular blockade defined as a train-of-four ratio (TOFr) <0.9 remains high. Even TOFr >0.9 cannot ensure adequate recovery of neuromuscular function when T1 height is not recovered completely. Thus, a mathematical correction of TOFr needs to be applied because the return of a normal TOFr can precede the return of a normal T1 twitch height. On the other hand, different muscles have different sensitivities to neuromuscular blockade agents; thus, complete recovery of one specific muscle group does not represent complete recovery of all other muscles. Therefore, our study aims to assess the muscle strength recovery of respiratory-related muscle groups by ultrasound and evaluate global strength using handgrip dynamometry in the early postoperative period when TOFr=0.9 and corrected TOFr (cTOFr)=0.9 with comparison of neostigmine versus sugammadex as reversal drugs.Methods and analysisThis study will be a prospective, single-blinded, randomised controlled trial involving 60 patients with American Society of Anesthesiologists physical status I–II and aged between 18 and 65 years, who will undergo microlaryngeal surgery. We will assess geniohyoid muscle, parasternal intercostal muscle, diaphragm, abdominal wall muscle and handgrip strength at four time points: before anaesthesia, TOFr=0.9, cTOFr=0.9 and 30 min after admission to the post anaesthesia care unit. Our primary objective will be to compare the effects of neostigmine and sugammadex on the recovery of muscle strength of different muscle groups in the early postoperative period when TOFr=0.9 and cTOFr=0.9. The secondary objective will be to observe the difference of muscle strength between the time points of TOFr=0.9 and cTOFr=0.9 to find out the clinical significance of cTOFr >0.9.Ethics and disseminationThe protocol was reviewed and approved by the Ethics Committee of The First Affiliated Hospital, Sun Yat-sen University. The findings will be disseminated to the public through peer-reviewed scientific journals.Trial registration numberChiCTR2000033832.

Risk Of Death

Abstract Purpose To assess the prevalence of frailty in the preoperative period and to evaluate its effect on the risk of complications and adverse outcomes in patients undergoing coronary artery bypass grafting (CABG). Methods 303 patients undergoing preoperative management for elective primary CABG were recruited in the study. The study cohort was divided into three groups depending on the PRISMA-7 scores suggesting the presence or absence of frailty and the presence of prefrailty. Statistical analysis was performed using the commercially available software package STATISTICA 8.0.360.0 for Windows (StatSoft, Inc., USA) and SPSS Statistics v. 17.0.0. Results 46 (15%) patients had frailty, while 49 (16%) patients were diagnosed with prefrailty. 208 (69%) patients did not have any signs of frailty. All three groups had significant age differences, therefore only elderly patients aged of 67.0±6.5 years with frailty were allocated for subsequent analysis (prefrailty group - 62.3±7.4 years old, patients without frailty - 60.0±7.7 years, p=0.003). Patients with frailty or prefrailty more often suffered from diabetes mellitus (patients without frailty - 19.2%, prefrailty group - 30.6% and frailty group - 28.3%, p=0.05), arterial hypertension (69.2%, 93.9% and 95.7%, respectively, p<0.001), atrial fibrillation or flutter (7.2%, 14.3% and 19.6%, respectively, p=0.03), chronic heart failure class 3–4 (7.2%, 10.2% and 8.7%, respectively, p=0.002), and peripheral arterial disease (22.6%, 38.8% and 58.7%, respectively, p<0.001). Three groups were comparable in main clinical and demographic parameters. There were no significant differences found in the incidence of postoperative atrial fibrillation or flutter (15.9%, 8.2% and 6.5%, respectively, p=0.07) and infections (1.9%, 0% and 4.3%, respectively, p=0.640). The incidence of myocardial infarction in the intra- and early postoperative period after CABG did not differ significantly between the groups (0.5%, 2% and 0%, respectively, p=0.328) as well as the incidence of stroke (2.4%, 2% and 0%, respectively, p=0.640). Patients with frailty and prefrailty had significantly higher cerebrovascular and cardiovascular mortality compared to those without frailty (8.2%, 2.2% and 0.5%, respectively, p=0.001). Conclusion Almost 15% of patients referred to CABG suffered from frailty. The presence of prefrailty or frailty increases the risk of death in the early postoperative period after CABG.

Abstract Objectives Opioids are commonly prescribed post-surgery. We investigated the proportion of patients who were prescribed any opioids 6–12 months after two common surgeries – laparoscopic cholecystectomy and gastric by-pass (GBP) surgery. A secondary aim was to examine risk factors prior to surgery associated with the prescription of any opioids after surgery. Methods We performed a retrospective observational study on data from medical records from patients who underwent cholecystectomy (n=297) or GBP (n=93) in 2018 in the Region of Västerbotten, Sweden. Data on prescriptions for opioids and other drugs were collected from the patients` medical records. Results There were 109 patients (28%) who were prescribed opioids after discharge from surgery but only 20 patients (5%) who still received opioid prescriptions 6–12 months after surgery. All 20 of these patients had also been prescribed opioids within three months before surgery, most commonly for back and joint pain. Only 1 out of 56 patients who were prescribed opioids preoperatively due to gallbladder pain still received prescriptions for opioids 6–12 months after surgery. Although opioid use in the early postoperative period was more common among patients who underwent cholecystectomy, the patients who underwent GBP were more prone to be “long-term” users of opioids. In the patients who were prescribed opioids within three months prior to surgery, 8 out of 13 patients who underwent GBP and 12 of the 96 patients who underwent cholecystectomy were still prescribed opioids 6–12 months after surgery (OR 11.2; 95% CI 3.1–39.9, p=0,0002). Affective disorders were common among “long-term” users of opioids and prior benzodiazepine and amitriptyline use were significantly associated with “long-term” opioid use. Conclusions The proportion of patients that used opioids 6–12 months after cholecystectomy or GBP was low. Patients with preoperative opioid-use experienced a significantly higher risk of “long-term” opioid use when undergoing GBP compared to cholecystectomy. The indication for being prescribed opioids in the “long-term” were mostly unrelated to surgery. No patient who was naïve to opioids prior surgery was prescribed opioids 6–12 months after surgery. Although opioids are commonly prescribed in the preoperative and in the early postoperative period to patients with gallbladder disease, there is a low risk that these prescriptions will lead to long-term opioid use. The reasons for being prescribed opioids in the long-term are often due to causes not related to surgery.
