RESUMO
BACKGROUND: The appropriate size of GlideScope® blade for tracheal intubation in neonates and premature infants has not been established. We evaluated the impact of the size of the GlideScope® blade on the time taken for intubation in infants weighing 2.5-3.6 kg. METHODS: Sixty infants weighing 2.5-3.6 kg were randomly assigned to use of the size 1 blade (n=30) or the size 2 blade (n=30). The primary outcome was the time taken to intubate. Components related to the laryngoscopic view which could affect the duration of the intubating process were also analysed. RESULTS: The time required for tracheal intubation was shorter with the size 2 blade than with the size 1 blade (16 [14-20] s vs 22 [18-25] s, P=0.002; median difference=-5; 95% confidence interval, -7 to -2). The rate at which the tip of the tracheal tube was located at the centre of the laryngeal inlet was higher with the size 2 blade than with the size 1 blade (83% vs 40%, P<0.001). Correlation analysis indicated that the time required to find the tip of the tube was related to how far the lower border of the arytenoid cartilages was located from the mid-horizontal line of the monitor (r=0.28, P=0.033). CONCLUSION: Use of the size 2 blade significantly reduced the time required to intubate the trachea, compared with the size 1 GlideScope® blade in infants. CLINICAL TRIAL REGISTRATION: KCT 0003867.

BACKGROUND: Shoulder surgery in the beach chair position frequently causes hypotensive bradycardic events (HBEs), which are potentially associated with an increased risk of cerebral hypoperfusion. Here, we aimed to investigate the incidence and characteristics of symptomatic HBEs that require pharmacological interventions, and to identify specific risk factors associated with symptomatic HBEs. METHODS: We retrospectively examined the records of all patients aged ≥ 18 years who underwent shoulder arthrotomy in the beach chair position between January 2011 and December 2018 at Samsung Medical Center. For patients who experienced HBEs while in the beach chair position, the minimum heart rate and systolic blood pressure were noted, as was the total dose of ephedrine or atropine. RESULTS: Symptomatic HBEs occurred in 61.0% of all cases (256/420). Two patients with symptomatic HBEs experienced postoperative neurological complications. Multivariable logistic regression analysis showed that preoperative interscalene brachial plexus block (ISB) and advanced age were risk factors associated with symptomatic HBEs (odds ratio [OR]: 3.240, 95% CI: 2.003, 5.242, P < 0.001; OR: 1.060 for each 1-year increase, 95% CI: 1.044, 1.076, P < 0.001, respectively). Receiver operating curve analysis revealed that a threshold of 62 years of age had a moderate degree of accuracy for predicting symptomatic HBEs (area under curve: 0.764, 95% CI: 0.720, 0.804, P < 0.001). CONCLUSIONS: Considering the increasing risk of neurocognitive complications with aging, proactive hemodynamic management is needed, especially for elderly patients undergoing shoulder surgery in the beach chair position using ISB.

Pure laparoscopic donor right hepatectomy (PLDRH) is not a standard procedure for living donor liver transplantation but is safe and reproducible in the hands of experienced surgeons. However, the perioperative outcomes of PLDRH have not been fully evaluated yet. We used propensity score matching to compare the perioperative complications and postoperative short-term outcomes of donors undergoing PLDRH and open donor right hepatectomy (ODRH). A total of 325 consecutive donors who underwent elective, adult-to-adult right hepatectomy were initially screened. After propensity score matching, all patients were divided into two groups: PLDRH (n = 123) and ODRH (n = 123) groups. Perioperative complications and postoperative outcomes were compared between the two groups. Postoperative pulmonary complications were significantly more common in the ODRH than in the PLDRH group (54.5 vs. 31.7%, P < 0.001). The biliary complications (leak and stricture) were higher in PLDRH group than in the ODRH group (8% vs. 3%), but it failed to reach statistical significance (P = 0.167). Overall, surgical complication rates were similar between the two groups (P = 0.730). The opioid requirement during the first 7 postoperative days was higher in the ODRH group (686 vs. 568 mg, P < 0.001). The hospital stay and time to the first meal were shorter in the PLDRH than in the ODRH group (P = 0.003 and P < 0.001, respectively). PLDRH reduced the incidence of postoperative pulmonary complications and afforded better short-term postoperative outcomes compared to ODRH. However, surgical complication rates were similar in both groups.

In 2015, we experienced the largest in-hospital Middle East respiratory syndrome (MERS) outbreak outside the Arabian Peninsula. We share the infection prevention measures for surgical procedures during the unexpected outbreak at our hospital. We reviewed all forms of related documents and collected information through interviews with healthcare workers of our hospital. After the onset of outbreak, a multidisciplinary team devised institutional MERS-control guidelines. Two standard operating rooms were converted to temporary negative-pressure rooms by physically decreasing the inflow air volume (-4.7 Pa in the main room and -1.2 Pa in the anteroom). Healthcare workers were equipped with standard or enhanced personal protective equipment according to the MERS-related patient's profile and symptoms. Six MERS-related patients underwent emergency surgery, including four MERS-exposed and two MERS-confirmed patients. Negative conversion of MERS-CoV polymerase chain reaction tests was noticed for MERS-confirmed patients before surgery. MERS-exposed patients were also tested twice preoperatively, all of which were negative. All operative procedures in MERS-related patients were performed without specific adverse events or perioperative MERS transmission. Our experience with setting up a temporary negative-pressure operation room and our conservative approach for managing MERS-related patients can be referred in cases of future unexpected MERS outbreaks in non-endemic countries.

Corticosteroids have been empirically administered to reduce the rate of acute respiratory distress syndrome (ARDS) after esophagectomy. However, their efficacy remains controversial, and corticosteroids may increase the risk of graft dehiscence and infection, which are major concerns after esophagectomy. Therefore, we compared the incidence of composite complications (ARDS, graft dehiscence and infection) after esophagectomy between patients who received a preventive administration of corticosteroids and those who did not. All patients who underwent esophagectomy from 2010 to 2015 at a tertiary care university hospital were reviewed retrospectively (n = 980). Patients were divided into Steroid (n = 120) and Control (n = 860) groups based on the preventive administration of 100 mg hydrocortisone during surgery. The primary endpoint was the incidence of composite complications. The incidence of composite complications was not different between the Control and Steroid groups (17.4% vs. 21.7% respectively; P = 0.26). The incidence rates of complications in each category were not different between the Control and Steroid groups: ARDS (3.8% vs. 5.0%; P = 0.46), graft dehiscence (4.8% vs. 6.7%; P = 0.37), and infection (12.8% vs. 15.8%; P = 0.36). Propensity score matching revealed that composite complications (20.0% vs. 21.7%; P = 0.75), ARDS (4.3% vs. 5.2%; P = 0.76) and infection (16.5% vs. 15.7%; P = 0.86) were not different between the Control and Steroid group, but the incidence of graft dehiscence was higher in the Steroid group than in the Control group (0.9% vs. 7.0%; P = 0.0175). In conclusions, the preventive use of corticosteroids did not reduce the incidence of ARDS, but may be related to an increased incidence of graft dehiscence. Therefore, routine administration of corticosteroids to prevent ARDS is not recommended in esophagectomy.
