Background: In emergency surgeries requiring endotracheal intubation, the time to effect of neuromuscular blocking drugs is a crucial time to avoid hypoxia and aspiration into the lungs. Various strategies have been undertaken to shorten this time. All these methods have positive results but some are associated with side effects. The effectiveness of a muscle relaxant can either be assessed using the train of four or intubating conditions on the Goldberg scale. In this study, we investigated the...

Abstract Critical care is a young specialty in Kenya. From its humble beginnings in the 1960s to present day Kenya, the bulk of this service has largely been provided by anaesthetists. We provide a detailed account of the growth and development of this specialty in our country, the attempts made by our people to grow this service within our borders and the vital role our international partners have played throughout this process. We also share a selection of our successes over the years, the cha...

Background: The manufacturer Ambu® recommends that the AuraOnce™ laryngeal mask be removed once the patient is fully awake. Studies have shown benefit in removal of the laryngeal mask airway while a patient is deeply anaesthetized. Current evidence is inconclusive, as to which approach is preferable and safer in adults. Methods: one hundred and sixteen adult patients were randomly assigned to two groups of 58. For the deep arm; The AuraOnceTM laryngeal mask was removed after attaining an end tid...

Background: Propofol is administered as intermittent boluses to achieve deep sedation to facilitate oesophagogastroduodenoscopy. Target controlled infusion (TCI) can be employed for this purpose. Methods: 176 adults were randomly allocated into two groups of 88 patients. Control group: Received an initial bolus of propofol 1mg/kg, with repeat boluses of 0.25mg/kg. Intervention group: Received an initial target effect-site concentration of 4mcg/ml, followed by maintenance target effect-site conce...

Background: Spinal anaesthesia is an effective regional anaesthesia technique, which is preferred in almost 86% of caesarean sections in the United States and United Kingdom. Eighty percent of caesarean sections done at the Aga Khan University hospital are under spinal anaesthesia. Shivering is a common complication of spinal anaesthesia, it occurs in 40%-64% of patients after neuraxial anaesthesia. Shivering may cause maternal and fetal hypoxemia, maternal discomfort and a problem to the anaest...

Background: The use of drugs to attenuate the haemodynamic response to laryngoscopy and endotracheal intubation is the standard of care during elective surgery. Current evidence is conflicting concerning the best agent and optimal dose for this purpose. In the majority of cases, fentanyl is widely utilized to attenuate haemodynamic responses. Ketamine, an established available drug, has been scarcely studied in this regard at low doses and against varying doses of other common agents. Objective:...

Background: Laryngeal mask airways (LMAs) are widely used in anaesthesia and are considered to be generally safe. Postop- erative sore throat (POST) is a frequent complication following LMA use and can be very distressing to patients. The use of an LMA cuff pressure of between 30 and 32cm of H20 in alleviating post-operative sore throat has not been investigated. Objective: To compare the occurrence of POST between the intervention group in which LMA cuff pressures were adjusted to 30-32cm of H2...

Background: Remifentanil and dexmedetomidine are common agents used in general anaesthesia, monitored anaesthesia care and critical care. When combined with inhaled or intravenous anaesthetic agents intra-operatively, they provide analgesia, lower general anaesthetic requirements and provide sedation and analgesia in the peri-operative period if indicated. Pharmacodynamically, they cause hypotension and bradycardia which are reversible if well managed. Past studies of these drugs have shown a si...

Background: There is increasing evidence that the incidence of postoperative residual paresis after using neuromuscular blockers ranges from 24 to 50% in post anaesthesia care unit (PACU) and is associated with postoperative complications such as critical respiratory events as evidenced by hypoxia, hypoventilation and upper airway obstruction. Quantitative neuromuscular monitoring (such as the assessment of Train of four (TOF) ratio) and reversal of neuromuscular blockers has been shown to reduc...

Background: Preoperative anxiety is a common perioperative complication seen in approximately 11-80% of adults undergoing surgery. One of the goals of the preanaesthesia clinic is to allay anxiety. A preanaesthesia clinic evaluation has been shown to reduce anxiety however current studies on anxiety and the preanaesthesia clinic have not quantified this reduction. Objective: To determine the reduction in anxiety in patients evaluated in the clinic versus those evaluated in the ward. Methods: Fif...
