Abstract Background Rapid sequence induction is a well-established anesthetic procedure used in patients with a high risk of gastric aspiration. Suxamethonium has been the drug of choice; however, it carries potential risks and sometimes fatal outcomes. The aim of our study was to compare rocuronium after pretreatment with dexmedetomidine, to suxamethonium in providing excellent intubating conditions in rapid sequence induction in adults. Patients were randomly allocated to one of two groups, of 120 each. Control group (SS), patients received pretreatment with 10 ml 0.9% saline over 10 min and suxamethonium 1mg/kg. Experimental group (DR), received pretreatment with dexmedetomidine 1 μg/kg in 10 ml 0.9% saline over 10 min and rocuronium 0.6 mg/kg. Our primary endpoint was the number of patients who scored “excellent” on intubation conditions score, while secondary outcomes were hemodynamics and adverse events. Results The rate of excellent intubating conditions in the DR group 46% was insignificantly less (P value = 0.548) than that of the SS group 49% (relative risk (RR) of DR compared to SS = 1.04, with a confidence interval (CI) of 0.91–1.48. The percentage of patients with adverse events in the SS group was (30%) nearly more than twofold higher than that of the DR group (11%). A significant difference (P value = 0.016) in the incidence of excellent intubating conditions was higher in the female gender 59% compared to the male gender 38% (adjusted RR = 0.98, with a confidence interval of 0.79–1.1). Conclusion A combination of dexmedetomidine 1μg/kg and standard intubating dose of rocuronium 0.6 mg/kg provided comparable endotracheal intubation conditions to suxamethonium 1 mg/kg during RSI and might be used as an alternative to suxamethonium in situations where suxamethonium is contraindicated.

Background: Manage and deal with the pregnant patient undergoing anesthesia for surgical non-obstructed surgery, assess the effects of non-obstetric surgeries on both fetus and mother during pregnancy, and measures to prevent it. Methods: A review search study was currently managed in PubMed, MEDLINE, Embase, Science gate, Elsevier, Scientific report, Google Scholar, and Cochrane Evidence-Based Medicine Reviews, after obtaining approval from the ethics committee of Tehran University of Medical Sciences. All the reviews identified were restricted to human studies and available in English. Results: Elective surgery ideally should be avoided during pregnancy while emergency surgery should proceed with consideration for the anesthetic implications of the altered physiology of pregnancy. Caution must be taken during anesthetic application and Airway management. Conclusion: Pre-oxygenation is essential and consider the rapid-sequence induction accompanied with cricoid pressure to lower the incidence of aspiration. Lower MAC values of the volatile anesthetic should be used and medications titrated to preferably produce beneficial effects only.

Abstract Background Rapid Sequence Induction (RSI) is used for emergency tracheal intubation to minimise the risk of pulmonary aspiration of stomach contents. Ketamine and propofol are two commonly used induction agents for RSI in trauma patients. Yet, no consensus exists on the optimal induction agent for RSI in the trauma population. The aim of this study was to compare 30-day mortality in trauma patients after emergency intubation prehospitally or within 30 min after arrival in the trauma centre using either ketamine or propofol for RSI. Methods In this investigator-initiated, retrospective study we included adult trauma patients emergently intubated with ketamine or propofol registered in the local trauma registry at Rigshospitalet, a tertiary university hospital that hosts a level-1 trauma centre. The primary outcome was 30-day mortality. Secondary outcomes included hospital and Intensive Care Unit length of stay as well as duration of mechanical ventilation. We analysed outcomes using multivariable logistic regression models adjusting for age, sex, injury severity score, shock (systolic blood pressure < 90 mmHg) and Glasgow Coma Scale score before intubation and present results as odds ratios (ORs) with 95% confidence intervals. Results From January 1st, 2015 through December 31st, 2019 we identified a total of 548 eligible patients. A total of 228 and 320 patients received ketamine and propofol, respectively. The 30-day mortality for patients receiving ketamine and propofol was 20.2% and 22.8% (P = 0.46), respectively. Adjusted OR for 30-day mortality was 0.98 [0.58–1.66], P = 0.93. We found no significant association between type of induction agent and hospital length of stay, Intensive Care Unit length of stay or duration of mechanical ventilation. Conclusions In this study, trauma patients intubated with ketamine did not have a lower 30-day mortality as compared with propofol.

IntroductionThis article forms part of a series that seeks to identify interjurisdictional differences in the scope of paramedic practice and, consequently, differences in patient treatment based on which jurisdiction a patient is geographically located within at the time of their complaint. Methods The current Clinical Practice Guidelines of each Australasian domestic jurisdictional ambulance service (JAS) were accessed during June 2020 and updated in August 2021. Content was extracted and verified by 18 paramedics or managers representing all 10 JASs. ResultsAll JASs use intramuscular adrenaline as a first-line agent for adult anaphylaxis. Beyond this, significant differences exist in all treatments: five services provide nebulised adrenaline; 10 services provide adrenaline infusions (one requires doctor approval; one provides repeat boluses); six services provide nebulised salbutamol; two services provide salbutamol infusions (one requires doctor approval; one provides repeat boluses); five services provide nebulised ipratropium bromide; eight services provide corticosteroids (two restricted to intensive care paramedics (ICPs)); five services provide antihistamines for non-anaphylactic or post-anaphylactic reactions; four services provide glucagon (one requires doctor approval); magnesium is infused by ICPs in two services; 10 services allow unassisted intubation in anaphylactic arrest; one service allows ICPs to provide sedation-facilitated intubation or ketamine-only breathing intubation; eight services allow rapid sequence induction (two restricted to specialist roles). ConclusionThe JASs in Australasia have each created unique treatment clinical practice guidelines that are heterogeneous in their treatments and scopes of practice. A review of the evidence underlying each intervention is appropriate to determining best practice.

Objective: Comparison of post-operative pain between nalbuphine and tramadol in total intravenous anesthesia for dilation and evacuation. Methodology: This randomized controlled trial was conducted at Fatima Memorial Medical and Dental College and Hospital, Lahore during June 2019 to September 2020. We randomly enrolled in Two Groups-A, who received intravenous injection tramadol 1.5 mg/kg after rapid sequence induction with propofol2mg/kg, succinylcholine 1-1.5mg/kg followed by LMA insertion and Group-B those receiving nalbuphine0.1mg/kg after rapid sequence induction with propofol2mg/kg, succinylcholine 1-1.5mg/kg followed by LMA insertion. Consultant anesthetist administered these drugs and evaluated pain score after 30 mins of surgery done with the help of VAS. Results: Comparison of mean pain score in both groups shows 2.28+1.13 pain on VAS in Group-A and 1.07+0.82 in Group-B, p value was 0.0001 showing a significant difference. (Table 1) Conclusion: Post-operative pain is significantly lower in nalbuphinewhen compared with tramadol in total intravenous anesthesia for dilation and evacuation. Keywords: Dilation and evacuation, postoperative pain, nalbuphine, tramadol

Background: Severe coronavirus disease 2019 (COVID-19) can induce acute respiratory distress, which is characterized by tachypnea, hypoxia, and dyspnea. Intubation and mechanical ventilation are strategic treatments for COVID-19 distress or hypoxia. Methods: We searched PubMed, Embase, and Scopus databases to identify relevant randomized control trials, observational studies, and case series published from April 1, 2021. Results: 24 studies were included in this review. Studies had been conducted in the USA, China, Spain, South Korea, Italy, Iran, and Brazil. Most patients had been intubated in the intensive care unit. Rapid sequence induction had been mostly used for intubation. ROX index can be utilized as the predictor of the necessity of intubation in COVID-19 patients. According to the studies, the rate of intubation was 5 to 88%. It was revealed that 1.4 - 44.5% of patients might be extubated. Yet obesity and age (elderly) are the only risk factors of delayed or difficult extubation. Discussion and Conclusions: Acute respiratory distress in COVID-19 patients could require endotracheal intubation and mechanical ventilation. Severe respiratory distress, loss of consciousness, and hypoxia had been the most important reasons for intubation. Also, increased levels of C-reactive protein (CRP), ferritin, d-dimer, and lipase in combination with hypoxia are correlated with intubation. Old age, diabetes mellitus, respiratory rate, increased level of CRP, bicarbonate level, and oxygen saturation are the most valuable predictors of the need for mechanical ventilation. ICU admission mortality following intubation was found to be 15 to 36%. Awake-prone positioning in comparison with high-flow nasal oxygen therapy did not reduce the risk of intubation and mechanical ventilation. There was no association between intubation timing and mortality of the infected patients. Noninvasive ventilation may have survival benefits.
