RESUMEN
Anterior neck haematoma is a rare but potentially fatal emergency due to airway obstruction after a surgical intervention of the neck. Complete airway obstruction can be rapid and deteriorate exponentially. In a patient with a previously normal laryngeal view during his Sistrunk procedure, we describe the challenges and considerations faced in his second surgery for the evacuation of neck haematoma, which involved an unanticipated difficult airway after rapid sequence induction, necessitating rescue measures using low-skill fibreoptic intubation (LSFOI).
RESUMEN
BACKGROUND: Multimodal analgesia is now widely practised to minimise postoperative opioid consumption while optimising pain control. The aim of this meta-analysis was to assess the analgesic efficacy of erector spinae plane block (ESPB) in patients undergoing laparoscopic abdominal surgeries. This will be determined by perioperative opioid consumption, subjective pain scores, and incidences of postoperative nausea and vomiting. METHODS: The authors systemically searched electronic databases for randomised controlled trials (RCTs) published up to February 2023 comparing ESPB with other adjuvant analgesic techniques in laparoscopic abdominal surgeries. Nine randomised controlled trials encompassing 666 subjects were included in our study. RESULTS: ESPB was shown to reduce postoperative opioid consumption [mean difference (MD) of -5.95 mg (95% CI: -8.86 to -3.04; P <0.0001); I2 =89%], intraoperative opioid consumption MD of -102.4 mcg (95% CI: -145.58 to -59.21; P <0.00001); I2 =39%, and incidence of nausea [RR 0.38 (95% CI: 0.25-0.60; P <0.0001); I2 =0%] and vomiting [RR 0.32 (95% CI: 0.17-0.63; P =0.0009); I2 =0%] in laparoscopic abdominal surgeries. Subgroup analysis on laparoscopic colorectal surgeries further showed reduction in postoperative pain scores MD of -0.68 (95% CI: -0.94 to -0.41); P <0.00001; I2 =0%]. CONCLUSIONS: This study concludes that ESPB is a valuable technique with proven efficacy to potentially promote faster postoperative recovery through optimising pain control while minimising opioid requirements.

BACKGROUND: Ageing population is a worldwide phenomenon with correspondingly higher proportion of older patients being treated in the hospital setting. Sarcopenia, which increases with age, has serious negative implications on health, hospitalisation, and overall postoperative recovery. There is no mutual consensus on perioperative management of sarcopenia in surgical patients in Singapore. The purpose of this study is to create greater clarity pertaining to the recognition of sarcopenia, the application of assessment criteria of sarcopenia and perioperative management of surgical patients in Singapore. METHODS: A modified Delphi consensus consisting of a panel of experts from Singapore forming a multidisciplinary team, including surgeons, geriatricians, anesthesiologists, physiotherapists, and dieticians. Eight recommendations were proposed by the steering committee. Literature search from MEDLINE, Embase, and Scopus for articles up till June 2023 were performed to support recommendation statements. The expert panel voted on agreement to recommendation statements and graded the level of evidence supporting each statement through surveys to achieve consensus, set at 85% a priori. RESULTS: The panellists underwent two rounds of anonymized, independent voting before reaching consensus for all eight statements. After the first round, seven statements reached consensus, including the corresponding grading for level of evidence. The statement which did not achieve consensus was revised with supporting literature and after the second round of survey, all eight statements and level of evidence reached consensus, completing the Delphi process. These eight statements covered themes to (1) encourage the identification of sarcopenia, (2) guide preoperative, and (3) postoperative management of sarcopenia. CONCLUSION: With the varying approaches in perioperative management, poor understanding of and identification of sarcopenia can result in suboptimal management of sarcopenia in surgical patients. Given the abundance of evidence linking beneficial impact on recovery and postoperative complications with prudent management of sarcopenia, it is imperative and urgent to achieve awareness and consensus.

Background Over the past decade, telemedicine has experienced significant growth due to technological advancement, and the coronavirus disease 2019 (COVID-19) pandemic further accelerated its adoption. However, the field of anesthesiology has been slow in integrating and embracing telemedicine compared to other medical specialties. Methods We conducted an observational pilot feasibility study at a tertiary hospital in Singapore to assess the viability of a telemedicine hybrid protocol for preoperative anesthetic assessment. The study included patients aged 21 to 65 years, classified as American Society of Anesthesiology (ASA) physical status class 1 or 2, with a body mass index (BMI) below 35 kg/m2, who were capable of managing video conferencing. The patients selected were scheduled for low-risk surgeries. The primary objective was to evaluate the medical and technical feasibility of our telemedicine hybrid protocol, while the secondary objectives included assessing patient satisfaction and obtaining feedback from relevant stakeholders. Results From November 2021 to April 2022, a total of 116 patients were recruited, with 96 patients completing the study. No technical difficulties, surgical case cancellations, or incidents of unanticipated difficult airways were reported. The majority of survey respondents (88%) expressed satisfaction with the video consultation and indicated a preference for it over physical consultations for future preoperative anesthesia evaluations. Conclusion Based on our findings, a telemedicine hybrid protocol for preoperative anesthetic assessment demonstrated both technical and medical feasibility while yielding high patient satisfaction. Future research could focus on expanding the protocol to encompass more complex surgeries and include patients with higher ASA status.
RESUMEN
BACKGROUND: The Erector Spinae Plane (ESP) block is a recent development in the field of regional anaesthesia and has been increasingly explored for abdominal surgeries to reduce opioid use and improve pain control. Colorectal cancer is the commonest cancer in multi-ethnic Singapore and requires surgery for curative treatment. ESP is a promising alternative in colorectal surgeries, but few studies have evaluated its efficacy in such surgeries. Therefore, this study aims to evaluate the use of ESP blocks in laparoscopic colorectal surgeries to establish its safety and efficacy in this field. METHODS: A prospective two-armed interventional cohort study comparing T8-T10 ESP blocks with conventional multimodal intravenous analgesia for laparoscopic colectomies was conducted in a single institution in Singapore. The decision for doing an ESP block versus conventional multimodal intravenous analgesia was made by a consensus between the attending surgeon and anesthesiologist. Outcomes measured were total intra-operative opioid consumption, post-operative pain control and patient outcome. Post-operative pain control was measured by pain score, analgesia use, and amount of opioids consumed. Patient outcome was determined by presence of ileus. RESULTS: A total of 146 patients were included, of which 30 patients received an ESP block. Overall, the ESP group had a significantly lower median opioid usage both intra-operatively and post-operatively (p = 0.031). Fewer patients required patient-controlled analgesia and rescue analgesia post-operatively for pain control (p < 0.001) amongst the ESP group. Pain scores were similar and post-operative ileus was absent in both groups. Multivariate analysis found that the ESP block had an independent effect on reducing intra-opioid consumption (p = 0.014). Multivariate analysis of post-operative opioid use and pain scores did not yield statistically significant results. CONCLUSIONS: The ESP block was an effective alternative regional anaesthesia for colorectal surgery that reduced intra-operative and post-operative opioid use while attaining satisfactory pain control.

Von Hippel-Lindau (VHL) syndrome is a rare autosomal dominant disease with incomplete penetrance and variable expression. The features of cerebellar and spinal tumors, pheochromocytomas, and increased intracranial pressure complicate the anesthetic management of such patients. This report describes the anesthetic management of a parturient with VHL disease and highlights the importance of proper surveillance, vigilant management, and individualized treatment plans from a multidisciplinary team.
RESUMEN
Modern diets are largely heat-processed and as a result contain high levels of advanced glycation end products (AGEs). Dietary advanced glycation end products (dAGEs) are known to contribute to increased oxidant stress and inflammation, which are linked to the recent epidemics of diabetes and cardiovascular disease. This report significantly expands the available dAGE database, validates the dAGE testing methodology, compares cooking procedures and inhibitory agents on new dAGE formation, and introduces practical approaches for reducing dAGE consumption in daily life. Based on the findings, dry heat promotes new dAGE formation by >10- to 100-fold above the uncooked state across food categories. Animal-derived foods that are high in fat and protein are generally AGE-rich and prone to new AGE formation during cooking. In contrast, carbohydrate-rich foods such as vegetables, fruits, whole grains, and milk contain relatively few AGEs, even after cooking. The formation of new dAGEs during cooking was prevented by the AGE inhibitory compound aminoguanidine and significantly reduced by cooking with moist heat, using shorter cooking times, cooking at lower temperatures, and by use of acidic ingredients such as lemon juice or vinegar. The new dAGE database provides a valuable instrument for estimating dAGE intake and for guiding food choices to reduce dAGE intake.

CONTEXT: Increased oxidant stress and inflammation (OS/infl) are linked to both aging-related diseases and advanced glycation end products (AGEs). Whereas AGE receptor-1 (AGER1) reduces OS/infl in animals, this has not been assessed in normal humans. OBJECTIVE: The objectives of the study were to determine whether AGER1 correlates with AGEs and OS/infl and a reduction of dietary AGEs (dAGEs) lowers OS/infl in healthy adults and chronic kidney disease (CKD-3) patients. DESIGN: This study was cross-sectional with 2-yr follow-up studies of healthy adults and CKD-3 patients, a subset of which received a reduced AGE or regular diet. SETTING: The study was conducted at general community and renal clinics. PARTICIPANTS: Participants included 325 healthy adults (18-45 and >60 yr old) and 66 CKD-3 patients. INTERVENTION: An isocaloric low-AGE (30-50% reduction) or regular diet was given to 40 healthy subjects for 4 months and to nine CKD-3 patients for 4 wk. MAIN OUTCOME: Relationships between age, dAGEs, serum AGEs, peripheral mononuclear cell AGE-receptors, and OS/Infl before and after reduction of dAGE intake were measured. RESULTS: AGEs, oxidant stress, receptor for AGE, and TNFalpha were reduced in normal and CKD-3 patients after the low-AGE diet, independently of age. AGER1 levels in CKD-3 patients on the low-AGE diet resembled 18- to 45-yr-old normal subjects. Dietary, serum, and urine AGEs correlated positively with peripheral mononuclear cell AGER1 levels in healthy participants. AGER1 was suppressed in CKD-3 subjects, whereas receptor for AGE and TNFalpha were increased. CONCLUSIONS: Reduction of AGEs in normal diets may lower oxidant stress/inflammation and restore levels of AGER1, an antioxidant, in healthy and aging subjects and CKD-3 patients. AGE intake has implications for health outcomes and costs and warrants further testing.
