ABSTRACT

BACKGROUND: Intraoperative cardiac arrest (ICA) during liver transplantation (LT) is a rare surgical complication that results in devastating outcomes. Moreover, previous worldwide studies have found inconsistencies in the risk factors associated with ICA in LT. METHODS: This was a retrospective cohort study of adult patients who underwent LT between January and October 2021 at Siriraj Hospital, a tertiary care hospital. The incidence of ICA and outcomes of patients who experienced ICA were examined. Risk factors associated with ICA were investigated as a secondary objective. RESULTS: Among 342 patients, the incidence of ICA was 3.5% (95% CI 1.8%-6.1%). Of these, 33.3% died intraoperatively. Among patients with ICA, 41.7% died within 30 days, compared with only 7.6% in those without ICA (P = .002). Moreover, the in-hospital mortality rate of those with ICA was 58.3%, which was significantly higher than that of those without ICA (9.7%, P < .001). However, 41.7% of patients with ICA were discharged alive with long-term survival. Because ICA is a rare event, we found only 2 independent factors significantly associated with ICA. These factors include intraoperative temperature below 35°C, with an odds ratio (OR) of 6.07 (95% CI:1.32-27.88, P = .02) and elevated intraoperative serum potassium, with an OR of 4.57 (95% CI:2.15-9.67, P < .001). CONCLUSIONS: ICA is associated with high perioperative and in-hospital mortality. However, our findings suggest that with effective management of ICA, more than 40% of these patients could be discharged with excellent long-term outcomes. Hypothermia and hyperkalemia were independent risk factors significantly associated with ICA.

ABSTRACT

BACKGROUND: To assess the rate of conversion to general anesthesia, sedative and analgesic drug-sparing effects, and complications of popliteal sciatic nerve block (PSNB) compared with a sham block during lower limb angioplasty. METHODS: A randomized, controlled, double-blinded trial of patients with chronic limb-threatening ischemia (CLTI) who receive PSNB with 0.25% levobupivacaine 20 mL compared with a sham block (control) during lower limb angioplasty. Pain scores, conversion rate to general anesthesia, amount of sedoanalgesia drug usage, complications, and satisfaction with the anesthesia technique by surgeons and patients were assessed. RESULTS: Forty patients were enrolled in this study. Two of 20 (10%) control group patients were converted to general anesthesia, while none of the patients in the intervention group required general anesthesia (P = .487). Pain scores before PSNB did not differ between the groups (P = .771). After the block, pain scores in the block group were lower than those in the control group: 0 (0, 1.5) (median, interquartile range) and 2.5 (0.5, 3.5), respectively (P = .024). The analgesic effect persisted until immediately after the surgery (P = .035). There was no difference in pain scores at the 24-hours follow-up visit (P = .270). The total propofol and fentanyl dosage requirements, a number of patients who required propofol and fentanyl, side effects, and satisfaction were not different between the groups. No major complications were noted. CONCLUSIONS: PSNB provided effective pain relief during and immediately after lower limb angioplasty, but did not statistically affect the rate of conversion to general anesthesia, sedoanalgesia drug usage, or complications.

ABSTRACT

INTRODUCTION: Evidence suggests that immediate extubation after liver transplantation provides graft and economic benefits without compromising patient outcomes. This study tried to determine the incidence of immediate extubation, demonstrate related factors, and develop a predictive model from the significant factors. METHODS: This retrospective descriptive study included 240 out of 271 liver transplantation patients in the hospital liver transplant registry between 2004 and 2016. Extubated and non-extubated groups were statistically compared. RESULTS: The incidence of immediate extubation was 32.1%. It was associated with a MELD score ≤ 25 (adjusted OR, 5.17; 95% CI, 1.64-16.24; p = .005); packed red cells (PRC) transfusion ≤1600 ml (adjusted OR, 3.45; 95% CI, 1.82-6.53; p < .001); and no requirement for post-operative vasopressors (adjusted OR, 5.83; 95% CI, 2.30-14.77; p < .001). The immediate-extubation group had fewer complications and shorter hospital stays. A Siriraj Liver transplant Extubation Score (SLES) of 5 yielded the best prediction of safe immediate extubation. CONCLUSIONS: An incidence of 32.1% was found for immediate extubation following liver transplantation. Associated factors were a MELD score ≤ 25, a lower amount of transfused blood, and no requirement for post-operative vasopressors. An SLES score of 5 predicted safe immediate extubation.

ABSTRACT

BACKGROUND: The Coronavirus disease 2019 (COVID-19) pandemic continues to spread across the world. Hence, there is an urgent need for rapid, simple, and accurate tests to diagnose severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Performance characteristics of the rapid SARS-CoV-2 antigen detection test should be evaluated and compared with the gold standard real-time reverse transcription-polymerase chain reaction (RT-PCR) test for diagnosis of COVID-19 cases. METHODS: The rapid SARS-CoV-2 antigen detection test, Standard™ Q COVID-19 Ag kit (SD Biosensor®, Republic of Korea), was compared with the real-time RT-PCR test, Allplex™ 2019-nCoV Assay (Seegene®, Korea) for detection of SARS-CoV-2 in respiratory specimens. Four hundred fifty-four respiratory samples (mainly nasopharyngeal and throat swabs) were obtained from COVID-19 suspected cases and contact individuals, including pre-operative patients at Siriraj Hospital, Bangkok, Thailand during March-May 2020. RESULTS: Of 454 respiratory samples, 60 (13.2%) were positive, and 394 (86.8%) were negative for SARS-CoV-2 RNA by real-time RT-PCR assay. The duration from onset to laboratory test in COVID-19 suspected cases and contact individuals ranged from 0 to 14 days with a median of 3 days. The rapid SARS-CoV-2 antigen detection test's sensitivity and specificity were 98.33% (95% CI, 91.06-99.96%) and 98.73% (95% CI, 97.06-99.59%), respectively. One false negative test result was from a sample with a high real-time RT-PCR cycle threshold (Ct), while five false positive test results were from specimens of pre-operative patients. CONCLUSIONS: The rapid assay for SARS-CoV-2 antigen detection showed comparable sensitivity and specificity with the real-time RT-PCR assay. Thus, there is a potential use of this rapid and simple SARS-CoV-2 antigen detection test as a screening assay.

ABSTRACT

The aim of this study was to identify the characteristics of perioperative convulsion and to suggest possible correcting strategies. The multi-centre study was conducted prospectively in 22 hospitals across Thailand in 2015. The occurrences of perioperative adverse events were collected. The data was collated by site manager and forwarded to the data management unit. All perioperative convulsion incidences were enrolled and analysed. The consensus was documented for the relevant factors and the corrective strategies. Descriptive statistics were used. From 2,000 incident reports, perioperative convulsions were found in 16 patients. Six episodes (37.5%) were related to anaesthesia, 31.3% to patients, 18.8% to surgery, and 12.5% to systemic processes. The contributing factor was an inexperienced anaesthesia performer (25%), while the corrective strategy was improvements to supervision (43.8%). Incidents of perioperative convulsion were found to be higher than during the last decade. The initiation and maintenance of safe anaesthesia should be continued.

ABSTRACT

OBJECTIVE: To reduce the onset of 0.5% bupivacaine by adding 2% lidocaine with 0.5% bupivacaine for ultrasound-guided and double stimulation technique at musculocutaneous and radial nerve for infraclavicular brachial plexus block. DESIGN: Prospective randomized double-blinded, controlled trial study. MATERIAL AND METHOD: 90 patients undergoing creation of arteriovenous fistula under ultrasound-guided infraclavicular brachial plexus block were randomized into 2 groups. Gr B (46 patients) received 0.5% bupivacaine 30 mL and Gr BL (44 patients) received mixture of 0.5% bupivacaine 20 mL and 2% lidocaine 10 mL. The onset of sensory block were assessed by response to pinprick (grading: 0 = no sensation, 1 = hypoesthesia, and 2 = normal sensation). Rescue analgesia during the operation, duration of sensory and motor blockade were recorded. Surgeon and patient satisfactions are also evaluated using 6-point scale (0 = dissatisfied to 5 = very satisfied). RESULTS: There were no significant difference in the onset time of either group. Duration of sensory and motor block was not different. Surgeons' and patients' satisfaction were also not significantly different between the groups. CONCLUSION: Mixing 2% lidocaine with 0.5% bupivacaine to the final concentration of 0.67%for lidocaine and 0.33% for bupivacaine does not reduce the onset of ultrasound-guided infraclavicular brachial plexus block.

ABSTRACT

OBJECTIVE: The aim of the present study was to test the efficacy of epidural nalbuphine 5 mg for prevention of morphine-induced pruritus. MATERIAL AND METHOD: Parturients, ASA I-II scheduled for elective cesarean section under epidural anesthesia were randomized into 3 groups: the placebo group, N-5 group, and N-10 group received 4 ml epidural solution containing morphine 4 mg plus either saline, nalbuphine 5 mg, and nalbuphine 10 mg respectively. Pain score at rest and on movement, incidence and severity of pruritus, sedation score, and pethidine consumption were recorded for 24 hours. RESULTS: The 182 parturients were randomized into 60 in the placebo group, 61 in the N-5 group, and 61 in the N-10 group. The severity of pruritus was significantly lower at 3, 6, 9 and 12 h postpartum in the N-5 group and the N-10 group had a lower degree of pruritus at 3 and 6 h postpartum compared to placebo. The VAS pain scores at rest and on movement were significantly higher in the N-10 group at 3, 6, 9, 12 and 18 h postpartum compared to the placebo and significantly higher at 3 h, 6 h postpartum compared to the N-5 group (p < 0.05). Patient's satisfactions were high in all groups without any significant difference between groups. CONCLUSION: Epidural nalbuphine 5 mg reduced severity of morphine induced pruritus for 12 h with statistically significant different advantages over epidural nalbuphine 10 mg without anti-analgesic effect. However the difference is too small to convey into clinical significant advantage.

ABSTRACT

In the present prospective, randomized controlled trial, 110 unpremedicated patients undergoing orthopedic surgery under regional anesthesia were randomly divided into 5 groups, with 22 patients in each. During the operation, group 1 listened to a pre-recorded explanation and music, group 2 listened to a subliminal sound, group 3 received propofol by patient-controlled sedation (PCS), group 4 received intravenous midazolam, and group 5 was the control group. Patients in the midazolam group were significantly more sedated than the control group at 1 hr into the operation. The group that listened to an explanation and music were significantly less satisfied than the propofol group at the end of the operation and 30 min. postoperatively. An incremental cost-effectiveness ratio showed that if explanation and music are used instead of propofol it would save 299.53 baht per patient, but the patient satisfaction score will be 17.26 points lower than if the more expensive drug is used.

ABSTRACT

OBJECTIVE: This study was designed to study the efficacy of Cuffed oropharyngeal airway (COPA) in the patients undergoing short surgical procedures at Siriraj Hospital. MATERIALS AND METHOD: A prospective study of 65 patients, age 15-65 years, scheduled for elective short surgical procedures under general anesthesia were managed with COPA. Lip-mandibular angle distance was used to indicate the appropriate size of COPA. Demographic characteristics, airway assessments, COPA size, insertion time, airway manipulation, complications during COPA insertion, removal and 2 hour postoperative period were recorded. RESULTS: Success rate of COPA insertion were 93.8 per cent and 4.6 per cent at 1st attempt and 2nd attempt respectively. Insertion time was 53.27 +/- 20.07 seconds. There were 84.4 per cent of patients who needed airway manipulation during anesthesia. The incidence of complications were 12.3 per cent, 13.8 per cent and 15.4 per cent during insertion, removal and 2 hour postoperatively respectively. CONCLUSION: COPA is a new adjunctive airway device designed for direct connection with breathing system with a high success rate of insertion. COPA placement is an easy technique to learn but it usually requires a high incidence of airway manipulations such as head turn, jaw thrust, head tilt, and chin lift, so skill and confidence in its use requires instruction and practice. It would be unwise to use a COPA in an emergency without first having become proficient in its use for routine cases.

ABSTRACT

A randomized controlled trial was conducted to determine the effect of adding epidural ketamine to epidural morphine comparing between giving ketamine at preincisional time and postincisional time on postoperative analgesia in patients undergoing gynecological operations. Eighty patients scheduled for gynecological operation under combined epidural-general anesthesia were randomly divided into 4 groups. Group 1 received epidural morphine 3 mg before skin incision. Group 2 received epidural morphine 3 mg after skin incision. Group 3 received epidural morphine 3 mg and ketamine 30 mg before skin incision. Group 4 received epidural morphine 3 mg and ketamine 30 mg after skin incision. Lidocaine 2 per cent with epinephrine 1:200,000 was used as the main anesthetic agent during the operation in all groups. Postoperative analgesics were pethidine 1 mg/kg intramuscularly or paracetamol 1,000 mg oral. The time to the first analgesic requirement and pain during 48 h were recorded. The amount of pethidine and paracetamol required and the time to the first dose of analgesic requirement were not significantly different among the groups. There were no differences in the incidences of pruritus, nausea, vomiting and nightmare. We concluded that adding ketamine to epidural morphine either by preincisional or postincisional administration did not potentiate the analgesic effect of epidural morphine.
