Background: Since the first case of severe acute respiratory syndrome Coronavirus-2 (SARS-CoV-2) occurred in Wuhan in December 2019, the virus has spread globally. The World Health Organization declared the virus outbreak a pandemic on March 11, 2020. On January 19, 2020, a 35-year-old woman who returned from China was confirmed as the first SARS-CoV-2 infected case in Korea. Since then, it has spread all over Korea.Case: We report the first case of a SARS-CoV-2 positive woman delivering a baby through cesarean section at 37+6 weeks of pregnancy in the Republic of Korea.Conclusions: This case suggested that negative pressure operating room, skillful medical team, and enhanced personal protective equipment including N95 masks, surgical cap, double gown, double gloves, shoe covers, and powered air-purifying respirator are required at the hospital for safe delivery in such a case.
Background: Acetylcholinesterase inhibitors (e.g., pyridostigmine bromide) are used for neuromuscular blockade (NMB) reversal in patients undergoing surgery under general anesthesia (GA). Concurrent use of anticholinergic agents (e.g., glycopyrrolate) decreases cholinergic side effects but can impede bowel movements. Sugammadex has no cholinergic effects; its use modifies recovery of gastrointestinal (GI) motility following laparoscopic cholecystectomy compared to pyridostigmine/glycopyrrolate. This study evaluated the contribution of sugammadex to the recovery of GI motility compared with pyridostigmine and glycopyrrolate. Methods: We conducted a prospective study of patients who underwent laparoscopic cholecystectomy. Patients were randomly allocated to the experimental group (sugammadex, Group S) or control group (pyridostigmine-glycopyrrolate, Group P). After anesthesia (propofol and rocuronium, and 2% sevoflurane), recovery was induced by injection of sugammadex or a pyridostigmine-glycopyrrolate mixture. As a primary outcome, patients recorded the time of their first passage of flatus ('gas-out time') and defecation. The secondary outcome was stool types. Results: One-hundred and two patients participated (Group S [n = 49], Group P [n = 53]). Mean time from injection of NMB reversal agents to gas-out time was 15.03 (6.36-20.25) h in Group S and 20.85 (16.34-25.86) h in Group P (P = 0.001). Inter-group differences were significant. Time until the first defecation as well as types of stools was not significantly different. Conclusions: Sugammadex after laparoscopic cholecystectomy under GA resulted in an earlier first postoperative passage of flatus compared with the use of a mixture of pyridostigmine and glycopyrrolate. These findings suggest that the use of sugammadex has positive effects on the recovery of GI motility.
Recognizing learners’ motivational problems in online remote learning, this study examined the patterns of learner’s academic emotions and facial expressions detected in asynchronous video-based learning. The research questions of this are: (1) What are the patterns between facial expressions and negative emotions (i.e., boredom, confusion, and frustration) that learners experienced during online video-based learning? (2) What are the learner’s overall perceptions about their emotions during online video-based learning? This study was conducted with 26 Korean adult learners who took an online video lecture via an asynchronous self-directed mode. Their facial expressions during online learning were recorded and analyzed for detecting affective states. Two judges trained in Ekman’s Facial Action Coding System (FACS) analyzed 210 scenes segmented from the recorded video data using a retrospective affect judgment procedure. The analysis identified 101 incidences of boredom, 82 confusions, and 62 frustrations. Moreover, using Spearman’s rank correlation coefficients and hierarchical clustering, we identified some patterns of significant relationships between facial action units and affective states. The interview data reveal that the potential reasons for negative emotions include lack of concentration, uninteresting content, and one-way content delivery method. Given the massive transition to online video-based learning during and after COVID-19, the results of this study can provide implications concerning how to detect and intervene in potential issues associated with learner’s motivation and affective states.
Spinal anesthesia is the standard anesthetic technique for performing Cesarean sections (C-section) to prevent complications related to airway management during general anesthesia, such as intubation failure or respiratory aspiration KSOA
Background: Sugammadex reverses rocuronium-induced neuromuscular blockade quickly and effectively. Herein, we compared the efficacy of sugammadex and pyridostigmine in the reversal of rocuronium-induced light block or minimal block in pediatric patients scheduled for elective entropion surgery.Methods: A prospective randomized study was conducted in 60 pediatric patients aged 2-11 years who were scheduled for entropion surgery under sevoflurane anesthesia. Neuromuscular blockade was achieved by administration of 0.6 mg/kg rocuronium and assessed using the train-of-four (TOF) technique. Patients were randomly assigned to 2 groups receiving either sugammadex 2 mg/kg or pyridostigmine 0.2 mg/kg and glycopyrrolate 0.01 mg/kg at the end of surgery. Primary outcomes were time from administration of reversal agents to TOF ratio 0.9 and TOF ratio 1.0. Time from the administration of reversal agents to extubation and postoperative adverse events were also recorded.Results: There were no significant differences in the demographic variables. Time from the administration of reversal agents to TOF ratio 0.9 and TOF ratio 1.0 were significantly shorter in the sugammadex group than in the pyridostigmine plus glycopyrrolate group: 1.30 ± 0.84 vs. 3.53 ± 2.73 min (P < 0.001) and 2.75 ± 1.00 vs. 5.73 ± 2.83 min (P < 0.001), respectively. Extubation time was shorter in the sugammadex group. Adverse events, such as skin rash, nausea, vomiting, and postoperative residual neuromuscular blockade (airway obstruction), were not statistically different between the two groups.Conclusions: Sugammadex provided more rapid reversal of rocuronium-induced neuromuscular blockade in pediatric patients undergoing surgery than did pyridostigmine plus glycopyrrolate.
