Use of Sugammadex in "Cannot Intubate, Cannot Ventilate" Scenarios: A Systematic Review of Case Reports.

After an induction dose of rocuronium, sugammadex in a dose of 16 mg.kg-1 has been shown to provide early reversal of the neuromuscular blockade. However, the use of sugammadex to rescue a "cannot intubate, cannot ventilate" (CICV) scenario remains controversial. The aim of this systematic review was to discuss case reports describing the use of sugammadex as a rescue reversal in CICV scenarios and analyze the influencing factors potentially shaping the outcome of such reversal. The study has been registered on International Prospective Register of Systematic Reviews (PROSPERO) (CRD42024514255). We conducted a systematic review of the literature using PubMed, Medline, and Embase. Records were included if they were case reports or case series published in peer-reviewed journals, describing the administration of sugammadex as a rescue reversal in CICV scenarios, and including clinical outcomes and details of the management. Sources were last searched on November 30, 2023. The articles selected were initially screened based on their titles and abstracts, and then complete articles were examined to determine their eligibility and compliance with the inclusion criteria. Two independent authors evaluated the quality of the individual studies using the Joanna Briggs Institute Critical Appraisal Checklist for Case Reports. Eight articles were included in our review. In all patients, CICV scenarios were declared minutes following induction. In 6/8 cases (75%), adequate spontaneous ventilation was restored after the administration of sugammadex. In the remaining 2 cases, sugammadex administration resulted in an obstructed pattern of breathing, and surgical airway was the successful rescue technique. There was wide variability in the sugammadex dose with a median (range) of 14 (5-16) mg.kg-1 and median timing (range) from rocuronium administration of 6 (2-10) minutes. This case-report-based review is susceptible to reporting bias and may not encompass all pertinent data and adverse events. Also, cases with both favorable and unfavorable outcomes may have not been published, and the heterogeneity of cases limits the ability to draw definitive conclusions. In summary, although these case reports suggest that sugammadex might be helpful in CICV scenarios, further research is needed to confirm its effectiveness. However, due to the rare occurrence of CICV events, gathering sufficient data for conclusive evidence may be challenging.

Opioid-free versus opioid-based anesthesia in major spine surgery: a prospective, randomized, controlled clinical trial.

BACKGROUND: Major spine surgery is associated with severe postoperative pain and increased opioid consumption. Opioid-free anesthesia (OFA) is thought to provide adequate intraoperative analgesia with reduced postoperative opioid consumption. The aim of this study is to compare the impact of intraoperative OFA approach to the conventional opioid-based anesthesia (OBA) on postoperative pain, opioid consumption, and related side effects in patients undergoing multilevel spinal fusion surgery. METHODS: Forty-eight patients undergoing elective major spine surgery were randomly allocated to either receive intraoperative dexmedetomidine and lidocaine (OFA group) or fentanyl during induction and intraoperative remifentanil (OBA group). All patients received intraoperative sevoflurane, propofol, rocuronium, ketamine, dexamethasone, ondansetron and postoperative paracetamol and patient-controlled analgesia device set to deliver intravenous morphine for 48 hours after surgery. Postoperative pain was measured using numerical rating scale. Opioid side effects were documented, when present. RESULTS: OFA group required less morphine in the first 24 hours post-surgery (17.28±12.25 mg versus 27.96±19.75 mg, P<0.05). The incidence of postoperative nausea and vomiting (PONV) was significantly lower in the OFA group. More patients in the OFA group required antihypertensive medications compared to patients in the OBA group (P<0.05). In the post anesthesia care unit, OFA patients had a significantly longer stay than OBA patients (114.1±49.33 min versus 89.96±30.71 min, P<0.05). CONCLUSIONS: OFA can be an alternative to OBA in patients undergoing multilevel spine fusion surgery. OFA reduces opioids consumption in the first 24 hours and PONV.

Adaptive leadership in crisis: a healthcare system's resilience journey.

BACKGROUND: Amid the complexities of a healthcare system facing economic collapse, pandemic challenges, a devastating human-made disaster, and critical staffing shortages, effective leadership becomes paramount. This article explores the adaptive leadership approach in the face of unprecedented challenges, drawing from the experiences of a healthcare system in Lebanon. METHODS: Anchored in Maslow's hierarchy of needs and guided by the adaptive leadership framework, leaders addressed challenges resulting from the economic crisis, compounded by the COVID-19 pandemic and a catastrophic explosion in Beirut, which tested the resilience of the healthcare system. RESULTS: Challenges ranged from resource shortages and financial strain to the critical staffing upheaval and psychological impact on healthcare workers. Prioritising physiological, safety, belongingness, self-esteem and self-actualisation needs, leaders implemented innovative strategies, including volunteer mobilisation, recruitment plans, makeshift clinics and psychological support. Transparent communication, self-esteem recognition and fostering resilience emerged as crucial components. CONCLUSION: The article provides insights into the practical application of adaptive leadership and Maslow's hierarchy of needs in navigating multifaceted crises within a healthcare setting. It underscores the significance of fostering resilience, prioritising the well-being of healthcare professionals and leveraging innovative solutions to ensure the continued delivery of high-quality care amid unprecedented challenges.

Ocular surface complications in children undergoing general anaesthesia: A prospective observational study.

OBJECTIVE: Ophthalmic complications frequently occur after procedures requiring general anaesthesia, but their incidence is widely variable and not well reported in the paediatric population. The aim was to identify the incidence and possible risk factors of postoperative ocular surface complications in a tertiary care centre. METHODS AND ANALYSIS: This is a prospective study for paediatric patients undergoing general anaesthesia. An ophthalmologist performed the ocular examination after surgery. Parameters assessed were tear breakup time, punctate epithelial erosions and corneal abrasions. Multivariate logistic regression model was used to assess risk factors. RESULTS: A total of 108 paediatric patients were recruited, 36.1% showed abnormal corneal finding: 32 (29.6%) had decreased tear breakup time, three (2.7%) had punctate epithelial erosions, three (2.7%) had both punctate epithelial erosions and decreased tear breakup time and one (0.9%) was found to have a unilateral corneal abrasion postoperatively. A higher rate of corneal complications was noted with younger age, prolonged surgery and surgery in the head and neck region. CONCLUSION: The rate of postoperative corneal abnormalities in children undergoing general anaesthesia was 36.1%, associated with younger age, prolonged surgery and surgery in the head and neck region.

The effect of the addition of nefopam to intraoperative ketoprofen and acetaminophen on postoperative morphine requirements after laparoscopic cholecystectomy: a randomized controlled trial.

BACKGROUND: Few studies investigated the use of nefopam for pain control after laparoscopic cholecystectomy in the context of multimodal analgesia. The aim of this study was to evaluate the effect of adding nefopam to ketoprofen and acetaminophen given before the end of laparoscopic cholecystectomy. METHODS: In this double-blind, controlled study, 90 patients undergoing laparoscopic cholecystectomy during sevoflurane-dexmedetomidine-based anesthesia were randomized to receive either ketoprofen and acetaminophen or nefopam, ketoprofen, and acetaminophen for postoperative pain control before the end of surgery. The primary outcome was total morphine consumption in the Postanesthesia Care Unit (PACU). RESULTS: PACU morphine consumption was significantly lower in the experimental group compared to the control group (0.9±1.8 mg vs. 2.3±2.4 mg, respectively; P=0.004, Cohen's d=0.63). In the experimental group, a smaller proportion of patients received morphine in PACU (24% vs. 60%, respectively; P=0.001), morphine during the first 24 hours after surgery (47% vs. 77%, respectively; P=0.004), and acetaminophen on the floor (76% vs. 93%, respectively; P=0.039) compared with the control group. The average pain score during PACU stay was also significantly lower in the experimental group (1.7±2.0 vs. 2.7±2.0, P=0.01). Median time to first morphine requirement (44.0 minutes, 95% CI [(31.96 to, 52.21)] was shorter in the control group than in the experimental group (higher than the 90 minutes-last time point taken in PACU). CONCLUSIONS: Adding nefopam to ketoprofen and acetaminophen before the end of laparoscopic cholecystectomy provides a reduction in morphine consumption with superior analgesia in PACU.

Harlequin syndrome during peripheral cardiopulmonary bypass in a patient with an obstructing tracheal schwannoma: A case report.

Surgical resection of obstructive tracheal tumors can be challenging to cardiothoracic surgeons and anesthesiologists. It is often difficult in these cases to maintain oxygenation by face mask ventilation during induction of general anesthesia. Also, the extent and location of these tracheal tumors can preclude conventional induction of general anesthesia and subsequent successful endotracheal intubation. Peripheral cardiopulmonary bypass (CPB) under local anesthesia and mild intravenous sedation may be safe to support the patient until securing a definitive airway. We describe a case of a 19-year-old female with a tracheal schwannoma, who developed differential hypoxemia (Harlequin, or North-South, syndrome) after institution of awake peripheral femorofemoral venoarterial (VA) partial CBP.

Sedation as an alternative anesthetic technique for frail patients in transurethral resection of the prostate.

Background: Transurethral resection of the prostate (TURP) under Monitored Anesthesia Care MAC/Sedation (macTURP), as compared with TURP under general (genTURP) or spinal (spTURP) anesthesia, is a safer and infrequently used technique reserved for high-risk patients. Objectives: The aim of this study is to compare 30-day postoperative outcomes of TURP using the three types of anesthesia techniques. Design and methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent TURP between 2008 and 2019. Demographics, lab values, medical history, and 30-day outcomes were compared. Univariate and multivariate regression models for postoperative complications were constructed. A propensity score-matched analysis was then performed for genTURP and macTURP and for spTURP and macTURP as a sensitivity analysis. Results: A total of 53,182 patients underwent TURP. Older patients (>80) with diabetes requiring insulin (7.9%), leukocytosis (7.4%), history of chronic obstructive pulmonary disease (COPD) (7.8%), dyspnea (7.2%), and of ASA > 2 (58.8%) were more likely to undergo macTURP as compared with genTURP (p < 0.013). SpTURP showed lower rates of urinary tract infection (UTI) [odds ratio (OR) = 0.869] as compared with genTURP (p = 0.049), whereas macTURP showed higher rates of major adverse cardiovascular events (OR = 2.179) as compared with genTURP (p = 0.005). All other postoperative complications showed similar rates between the three procedures. The propensity-matched cohorts demonstrated that no differences in postoperative complication rates were noted between macTURP and genTURP and between macTURP and spTURP. Conclusion: MacTURP was found to be feasible with a good safety profile as compared with genTURP and spTURP. MacTURP could be used in elderly, frail, and co-morbid patients with a similar safety profile as compared with more invasive anesthetic techniques.

Respiratory Adverse Events After LMA® Mask Removal in Children: A Randomized Trial Comparing Propofol to Sevoflurane.

BACKGROUND: The removal of the laryngeal mask airway (LMA®) in children may be associated with respiratory adverse events. The rate of occurrence of these adverse events may be influenced by the type of anesthesia. Studies comparing total intravenous anesthesia (TIVA) with propofol and sevoflurane are limited with conflicting data whether propofol is associated with a lower incidence of respiratory events upon removal of LMA as compared to induction and maintenance with sevoflurane. We hypothesized that TIVA with propofol is superior to sevoflurane in providing optimal conditions and improved patient's safety during emergence. METHODS: In this prospective, randomized, double-blind clinical trial, children aged 6 months to 7 years old were enrolled in 1 of 2 groups: the TIVA group and the sevoflurane group. In both groups, patients were mechanically ventilated. At the end of the procedure, LMAs were removed when patients were physiologically and neurologically recovered to a degree to permit a safe, natural airway. The primary aim of this study was to compare the occurrence of at least 1 respiratory adverse event, the prevalence of individual respiratory adverse events, and the airway hyperreactivity score following emergence from anesthesia between the 2 groups. Secondary outcomes included ease of LMA insertion, quality of anesthesia during the maintenance phase, hemodynamic stability, time to LMA removal, and incidence of emergence agitation. RESULTS: Children receiving TIVA with propofol had a significantly lower incidence (10.8.% vs 36.2%; relative risk, 0.29; 95% CI [0.14-0.64]; P = .001) and lower severity ( P = .01) of respiratory adverse outcomes compared to the patients receiving inhalational anesthesia with sevoflurane. There were no statistically significant differences in secondary outcomes between the 2 groups, except for emergence agitation that occurred more frequently in patients receiving sevoflurane ( P < .001). CONCLUSIONS: Propofol induction and maintenance exerted a protective effect on healthy children with minimal risk factors for developing perioperative respiratory complications, as compared to sevoflurane.

Reduction of Nonoperative Time Using the Induction Room, Parallel Processing, and Sugammadex: A Randomized Clinical Trial.

BACKGROUND: An important variable in the operating room is the nonoperative time (NOT), the time between skin closure on a previous case and skin incision on the following case. Mismanagement of NOT can result in significant financial losses and delays in the operating room (OR) schedule, which can negatively impact efficiency and patient, surgeon, and staff satisfaction. NOT includes general anesthesia induction time (IT), emergence time (ET), and turnover time (TOT), and can be calculated by adding the 3 components. OR efficiency can be increased by applying parallel processing for general anesthesia induction and OR cleaning and reversal of neuromuscular blockade with sugammadex to reduce the 3 components of NOT without compromising patient safety. METHODS: This is a prospective, randomized study of 111 patients 18 to 75 years of age, American Society of Anesthesiologists (ASA) I-III, undergoing surgery requiring general anesthesia and muscle relaxation. Patients were randomly assigned to the control group (traditional linear processing for induction of anesthesia and OR cleaning and neuromuscular blockade reversal with neostigmine/glycopyrrolate) and the active group (parallel processing for induction of anesthesia and OR cleaning and neuromuscular blockade reversal with sugammadex). The primary outcome measured is the difference in the NOT. The secondary outcomes are surgeon and patient satisfaction. RESULTS: NOT was significantly shorter in patients who underwent the parallel processing strategy and received sugammadex compared to the patients in the control group (25.0 [18.0-44.0] vs 48.0 [40.0-64.5] minutes; Cliff' delta = 0.57; P < .001). After excluding the cases in the experimental group that were put into sleep in the OR (ie, the first case of the room), IT, ET, TOT, and NOT were further reduced and remained statistically significantly lower than the control group. Satisfaction scores from surgeons were significantly higher in the active group than in the control group (P < .001). There was no significant difference in the satisfaction scores of patients between the 2 groups. CONCLUSIONS: Our study showed that interventions, such as parallel processing during induction of anesthesia and room cleaning instead of linear processing and the use of the faster-acting sugammadex instead of the combination of neostigmine and glycopyrrolate for the reversal of rocuronium-induced neuromuscular blockade, resulted in shorter IT, ET, TOT, and therefore NOT, in addition to higher surgeon's satisfaction.

Automated versus conventional perioperative glycemic control in adult diabetic patients undergoing open heart surgery.

BACKGROUND: Intraoperative glycemic variability is associated with increased risks of mortality and morbidity and an increased incidence of hyperglycemia after cardiac surgery. Accordingly, clinicians tend to use a tight glucose control to maintain perioperative blood glucose levels and therefore the need to develop a less laborious automated glucose control system is important especially in diabetic patients at a higher risk of developing complications. METHODS: Patients, aged between 40 and 75 years old, undergoing open heart surgery were randomized to either an automated protocol (experimental) or to the conventional technique at our institution (control). RESULTS: We showed that the percentage of patients maintained between 7.8-10 mmol.l-1 was not statistically different between the two groups, however, through an additional analysis, we showed that the proportion of patients whose glucose levels maintained between a safety level of 6.7-10 mmol.l-1 was significantly higher in the experimental group compared to control group, 14 (26.7%) vs 5 (17.2%) P = 0.025. In addition, the percentage of patients who had at least one intraoperative hyperglycemic event was significantly higher in the control group compared to the experimental group, 17 (58.6%) vs 5 (16.7%), P < 0.001 with no hypoglycemic events in the experimental group compared to two events in the control group. We also showed that longer surgeries can benefit more from using the automated glucose control system, particularly surgeries lasting more than 210 min. CONCLUSION: We concluded that the automated glucose control pump in diabetic patients undergoing open heart surgeries maintained most of the patients within a predefined glucose range with a very low incidence of hyperglycemic events and no incidence of hypoglycemic events.

Predictors of postoperative pain, opioid consumption, and functionality after arthroscopic shoulder surgery: A prospective observational study.

PURPOSE: This study aims to identify predictors of postoperative pain and opioid consumption after shoulder surgery to help optimize postoperative pain protocols. STUDY DESIGN: Observational cohort study. METHODS: One thirty-four patients undergoing arthroscopic shoulder repair were included. Variables related to the patient, surgery and anesthesia were collected and correlated with postoperative pain intensity, analgesic consumption, and functionality up to 1-month post-surgery. We used mixed-effect linear models to estimate the association of gender, interscalene block (ISB), preoperative shoulder pain, non-steroidal anti-inflammatory drugs (NSAIDs) consumption before surgery, and type of surgery with each of the following outcomes: postoperative pain scores, opioid consumption, and functionality. We further analyzed the data for pain scores and opioid consumption per body weight using the multiple linear regression analysis to demonstrate the aforementioned associations specifically at 1 h, 6 h, 12 h, 24 h, 72 h, 1 week and 1 month after surgery. RESULTS: Omitting the ISB was associated with higher postoperative pain and cumulative opioid consumption over the first 24 h after surgery. Rotator cuff repair and stabilization surgeries were found to be predictive of higher postoperative pain at 24 h, 72 h, and 1 week and lower functionality at 1 week after surgery. Preoperative shoulder pain and NSAIDs consumption were also predictive of postoperative pain and cumulative opioid consumption. CONCLUSION: Omitting a single shot ISB is a strong predictor of postoperative pain and opioid consumption in the early postoperative phase, beyond which the type of surgery, particularly rotator cuff repair and stabilization surgery, emerges as the most important predictor of postoperative pain and functionality.

Establishing a High-Quality Congenital Cardiac Surgery Program in a Developing Country: Lessons Learned.

Background: Developing countries are profoundly affected by the burden of congenital heart disease (CHD) because of limited resources, poverty, cost, and inefficient governance. The outcome of pediatric cardiac surgery in developing countries is suboptimal, and the availability of sustainable programs is minimal. Aim: This study describes the establishment of a high quality in-situ pediatric cardiac surgery program in Lebanon, a limited resource country. Methods: We enrolled all patients operated for CHD at the Children's Heart Center at the American University of Beirut between January 2014 and December 2018. Financial information was obtained. We established a partnership between the state, private University hospital, and philanthropic organizations to support the program. Results: In 5 years, 856 consecutive patients underwent 993 surgical procedures. Neonates and infants constituted 22.5 and 22.6% of our cohort, respectively. Most patients (82.6%) underwent one cardiac procedure. Our results were similar to those of the Society of Thoracic Surgeons (STS) harvest and to the expected mortalities in RACHS-1 scores with an overall mortality of 2.8%. The government (Public) covered 43% of the hospital bill, the Philanthropic organizations covered 30%, and the Private hospital provided a 25% discount. The parents' out-of-pocket contribution included another 2%. The average cost per patient, including neonates, was $19,800. Conclusion: High standard pediatric cardiac surgery programs can be achieved in limited-resource countries, with outcome measures comparable to developed countries. We established a viable financial model through a tripartite partnership between Public, Private, and Philanthropy (3P system) to provide high caliber care to children with CHD.

Propofol use in children: updates and controversies.

Advantages of propofol use in children may include less airway complications, less emergence agitation, and less postoperative behavioral changes. However, needle phobia and the complexity of total intravenous anesthesia set-up, as well as the pharmacokinetic and pharmacodynamic restrictions may limit the wide use of propofol-based anesthesia in the form of total intravenous anesthesia. Furthermore, pediatric infusion models and monitoring techniques are not fully validated yet. The choice of anesthesia type in children seems to be the result of a complex interplay between many factors related to the patient and the provider as well as logistic and operational factors that contribute to the decision-making process. Propofol has earned its place as a valuable choice in pediatric anesthesia. In addition, propofol and inhalation anesthesia should not be looked at as mutually exclusive; a combination of both may sometimes be the best approach to complex clinical dilemmas.

Dexmedetomidine for Improved Quality of Emergence From General Anesthesia: A Dose-Finding Study.

BACKGROUND: Dexmedetomidine provides smooth and hemodynamically stable emergence at the expense of hypotension, delayed recovery, and sedation. We investigated the optimal dose of dexmedetomidine for prevention of cough, agitation, hypertension, tachycardia, and shivering, with minimal side effects. METHODS: In this prospective, randomized, double-blind trial, 216 adult patients were randomly assigned to dexmedetomidine 1 µg/kg (D 1), 0.5 µg/kg (D 0.5), 0.25 µg/kg (D 0.25), or control (C). During emergence, cough, agitation, hemodynamic parameters, shivering, time to extubation, and sedation scores were recorded. RESULTS: A total of 190 patients were analyzed. The respective incidences for the groups D 1, D 0.5, and D 0.25 versus group C were 48%, 64%, and 64% vs 84% for cough-corrected P < .003 between groups D 1 and C; 33%, 34%, and 33% vs 72% for agitation-corrected P < .003 between group C and each of the study groups; and 4%, 2%, and 7% vs 22% for shivering-corrected P = .03 and corrected P = .009 between groups D 1 and D 0.5 versus group C, respectively. The percent increase from baseline blood pressure on extubation for the 3 treatment groups was significantly lower than group C. Percent increase in heart rate was lower than control in groups D 1 and D 0.5 but not in group D 0.25. Time to extubation and sedation scores were comparable. However, more hypotension was recorded during the emergence phase in the 3 treatment groups versus group C. CONCLUSIONS: D 1 at the end of surgery provides the best quality of emergence from general anesthesia including the control of cough, agitation, hypertension, tachycardia, and shivering. D 0.5 also controls emergence phenomena but is less effective in controlling cough. The 3 doses do not delay extubation. However, they cause dose-dependent hypotension.

The Effect of Intraoperative Dexmedetomidine Versus Morphine on Postoperative Morphine Requirements After Laparoscopic Bariatric Surgery.

BACKGROUND: Dexmedetomidine is an α2 receptor agonist with sedative and analgesic properties. During bariatric surgery, its use may reduce postoperative opioid requirements, reduce their side effects, and improve quality of recovery. The aim of this prospective randomized controlled trial was to compare the effect of dexmedetomidine bolus and infusion versus morphine bolus given prior to the end of laparoscopic bariatric surgery. METHODS: Sixty morbidly obese patients (BMI > 40 kg m-2) aged 18 to 60 years, undergoing laparoscopic sleeve gastrectomy, received morphine sulfate (bolus 0.08 mg kg-1 followed by a saline infusion) (group M, n = 30) or dexmedetomidine (loading dose of 1 µg kg-1 followed by 0.5 µg kg-1 h-1) (group D, n = 30) 30 min before the end of surgery. Data collected included morphine consumption in the post-anesthesia care unit (PACU) (primary outcome) and at 24 h, pain intensity, nausea, heart rate, blood pressure, vomiting, sedation, and quality of recovery. RESULTS: There was no significant difference in morphine consumption in the PACU (group D 12.2 ± 5.44 mg, group M 13.28 ± 6.64 mg, P = 0.54) or at 24 h (group D 40.67 ± 24.78 mg, group M 43.28 ± 27.79 mg, P = 0.75); when accounting for intraoperative morphine given group M had significantly higher morphine consumption when compared to group D (23.48 ± 6.22 mg vs. 12.22 ± 5.54 mg, respectively, P < 0.01). Group D patients had more cardiovascular stability. CONCLUSIONS: Dexmedetomidine given prior to end of laparoscopic sleeve gastrectomy provides the same level of postoperative analgesia as morphine with better hemodynamic profile.

Bilateral biochemically silent pheochromocytoma, not silent after all.

Pheochromocytoma is a sympathetic paraganglioma originating from the chromaffin cells. They are bilateral in 10% of cases and occur as a part of a MEN 2A or 2B syndromes. This is a case of bilateral asymptomatic pheochromocytomas diagnosed incidentally on imaging in a woman being investigated for secondary infertility. Laboratory tests were negative. Whole body FDG scan showed avid uptake of the tracer by both adrenal masses, but none in the thyroid. Hypertensive crisis occurred during right adrenalectomy on an unprepared patient in spite of clamping the adrenal vein, which raises the need for alpha-adrenergic blockade for patients undergoing adrenalectomy.
