Open-heart surgery is the leading cause of neuronal injury in the perioperative state, with some patients complicating with cerebrovascular accidents and delirium. Neurological fallout places an immense burden on the psychological well-being of the person affected, their family, and the healthcare system. Several randomised control trials (RCTs) have attempted to identify therapeutic and interventional strategies that reduce the morbidity and mortality rate in patients that experience perioperative neurological complications. However, there is still no consensus on the best strategy that yields improved patient outcomes, such that standardised neuroprotection protocols do not exist in a significant number of anaesthesia departments. This review aims to discuss contemporary evidence for preventing and managing risk factors for neuronal injury, mechanisms of injury, and neuroprotection interventions that lead to improved patient outcomes. Furthermore, a summary of existing RCTs and large observational studies are examined to determine which strategies are supported by science and which lack definitive evidence. We have established that the overall evidence for pharmacological neuroprotection is weak. Most neuroprotective strategies are based on animal studies, which cannot be fully extrapolated to the human population, and there is still no consensus on the optimal neuroprotective strategies for patients undergoing cardiac surgery. Large multicenter studies using universal standardised neurological fallout definitions are still required to evaluate the beneficial effects of the existing neuroprotective techniques.

Background: Orofacial clefts (OFCs) are the commonest congenital anomalies of the head and neck. Their aetiology is multifactorial, and prevalence has a geographical variation. This study sought to describe OFC cases that presented for surgery. Objectives: The study aimed to describe the preoperative characteristics, concomitant congenital anomalies and perioperative outcomes of children presenting for cleft repair surgery over a 5-year period at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH). Methods: A retrospective descriptive record review for children under the age of 14 years who presented for cleft repair surgery at Charlotte Maxeke Johannesburg Academic Hospital (CMJAH) during a 5-year period, from 1 January 2014 to 31 December 2018. Descriptive and comparative statistics were used to report the results. Results: A total of 175 records were included in the study. The median (IQR) age was 11 (6—27) months, with a predominance of males 98 (56%). Most of the children had cleft lip and palate (CLP) 71(41%). The prevalence of concomitant congenital anomalies was 22%, emanating mostly from head and neck congenital anomalies. Nine syndromes were identified in 15 children with syndromic clefts. Twenty-nine percent of children were underweight for age. There were 25 anaesthetic related complications, commonly airway related. Six children with complex multiple congenital anomalies were admitted in the intensive care unit postoperatively. No mortalities were recorded. Conclusion: Majority of children with orofacial clefts underwent cleft repair surgery without serious complications and intensive care unit admission. Only six children were diagnosed with significant anomalies needing intensive care management.

Background and purpose of the study: Intrathecal morphine (ITM) provides optimal postoperative analgesia in patients who are scheduled for total knee and hip operation with spinal anaesthesia. However, the ideal dose at which maximal analgesic effect occurs with minimal side effects is not known. This study aimed to describe the use of two doses of ITM and side effect profile in patients undergoing elective hip and knee arthroplasty. Methods: This was a prospective, descriptive, and contextual study conducted on patients who had total hip and knee replacement at Chris Hani Baragwanath Academic Hospital from 1 September to 30 November 2020. The sample size consisted of 66 patients who were 18 years and older, American Society of Anaesthesiology (ASA) classification 1–3, patients who had received either 100 mcg or 150 mcg ITM dose under spinal anaesthesia and sent to the ward postoperatively. Visual Analogue Scale (VAS) score was used to assess pain in the first 24 h, consumption of rescue analgesia and reported side effects were documented. Results: There was no relationship between age, weight, ASA classification or type of surgery and VAS score classification groups. Patients who received 100 mcg ITM had a higher median VAS pain score 2 (1–5) compared to those who received 150 mcg ITM 1 (0–2), p = 0.01. The need for rescue analgesia between the two groups was marginally less in the 150 mcg ITM group (p = 0.098). There was no difference in the rate of side effects between the 100 mcg ITM group [12 (41%)] and the 150 mcg ITM group [17 (59%)], p = 0.92. Rescue analgesia was marginally different between groups, p = 0.09. There were no real differences in the VAS pain scores between the total knee and total hip surgeries. None of the patients experienced clinically significant respiratory depression. Conclusion: The 150 mcg ITM dose provided good analgesic effects with longer duration of action and comparable side effect profile to the 100 mcg ITM dose. This dose was not associated with development of respiratory depression and can therefore be administered safely to patients who are discharged to the ward postoperatively in a resource constraint environment.

Anaesthesiologists regularly request and administer blood components to their patients, a potentially life-saving intervention. All anaesthesiologists must be familiar with the indications and appropriate use of blood and blood components and their alternatives, but close liaison with haematologists and their local haematology blood sciences laboratory is encouraged. In the last decade, there have been considerable changes in approaches to optimal use of blood components, together with the use of alternative products, with a need to update previous guidelines and adapt them for anaesthesiologists working throughout the hospital system.

Background: Neonates undergoing surgery are at greater risk of requiring packed red blood cell transfusion. Pediatric transfusion practices vary widely between countries and institutions, especially in the management of neonates.Aims: The aim of this study was to describe the use of intraoperative blood product transfusion during neonatal surgery in current clinical practice at our institution.Methods: A retrospective contextual, descriptive, and comparative study was conducted at Chris Hani Baragwanath Academic Hospital. A total of 1078 anesthetic records of neonates who underwent surgery from January 1, 2015 to December 31, 2019 were reviewed. Descriptive and inferential statistics were used to analyze the data.Results: Blood products were transfused during 374 (34.7%) neonatal surgeries. Packed red blood cells, platelet concentrate, and fresh frozen plasma were administered during 327 (30.3%), 133 (12.3%), and 85 (7.9%) of the total 1078 surgeries, respectively. The median (interquartile range) volume of packed red blood cells, fresh frozen plasma, platelets, and clear fluid administered was 15 (10–21.8) mL/kg, 12.3 (10–23.5) mL/kg, 13.6 (10–20.5) mL/kg, and 19 (9.1–28.8) mL/kg, respectively. Very low weight, low preoperative hemoglobin, long total anesthetic time, emergency surgery, and major surgery were independently associated with blood product transfusion. Gestational age at birth, blood product transfusion, emergency surgery, and major surgery were independently associated with the composite adverse outcomes. The median preoperative hemoglobin was 11.8 g/dL.Conclusions: Intraoperative blood product transfusion occurred at a much higher rate with a high median pre‐transfusion hemoglobin compared to other studies.
