Preventing hypothermia in pediatric neurosurgery in Africa-A randomized controlled non-inferiority trial of insulation versus active warming.

PURPOSE: The objective of this study was to compare the efficacy of a low-cost heat-preserving method in preventing intraoperative hypothermia with that of forced-air warming in a resource-limited setting. METHODS: In this randomized controlled non-inferiority trial, we recruited children younger than 12 years scheduled for cranial neurosurgery in a large East-African hospital. Patients were block-randomized by age to intraoperative warming measures using Hibler's method (intervention) or warm air (comparator). Hibler's group patients were circumferentially wrapped in transparent plastic sheeting (providing a vapor-trap) over a layer of cotton blankets, then laid on an insulating foam mattress. Warm air group patients were treated with forced-air convection via an underlying Snuggle Warm™ Pediatric Full Body mattress. Allocated warming measures were initiated in the operating theatre and discontinued upon anesthesia emergence. Perioperative temperatures were measured using noninvasive forehead probes (SpotOn™). The primary outcome was incidence of hypothermia (core temperature < 36.0° for longer than 5 min). Our null hypothesis was that Hibler's method is inferior in efficacy to the warm air method by a margin exceeding 20%. Among secondary outcomes were duration of hypothermia as proportion of surgical duration, incidence of postoperative shivering and rescue measure requirements. RESULTS: We analyzed data for 77 participants (Hibler's = 38; warm air = 39). There was no significant difference between the Hibler's and warm air arms of the study in the primary outcome of incidence of hypothermia (59.0% vs. 60.5% respectively; OR 1.07; 95% CI 0.43-2.65; p = .890). However, the risk difference (1.55%; 95% CI -0.20 to -0.24) exceeded the 0.2 margin and non-inferiority could not be declared. There was considerable need for rescue measures in both groups (71.1 0% vs. 69.2%; OR 1.09; 95% CI 0.41-2.90; p = .861). There was no statistically significant difference between groups for any prespecified secondary outcome. CONCLUSION: Although perioperative core temperatures were not significantly different, we could not declare an inexpensive heat-preserving method non-inferior to warm air convection in preventing intraoperative hypothermia in children undergoing anesthesia for cranial neurosurgery in a resource-limited setting. The extensive need for rescue measures may have masked important differences. TRIAL REGISTRATION: US National Institutes of Health Clinicaltrials.gov database (ID no. NCT02975817).

Multiorgan inflammatory syndrome associated with SARS-CoV-2 in a child. / Multiorgan inflammatorisk syndrom assosiert med sars-CoV-2 hos et barn.

This case report describes a child with heart failure and incipient multiorgan failure following infection with SARS-CoV-2. This is not COVID-19, but a delayed immune response known as multiorgan inflammatory syndrome. We have treated a number of children with this condition, and similar cases have been reported internationally. Patients can quickly become seriously ill, with high fever, gastrointestinal symptoms and cardiogenic shock.

Evaluation of training program for surgical trauma teams in Botswana.

BACKGROUND: Trauma represents a challenge to healthcare systems worldwide, particularly in low-and middle-income countries. Positive effects can be achieved by improving trauma care at the scene of the accident and throughout hospitalization and rehabilitation. Therefore, we assessed the long-term effects of national implementation of a training program for multidisciplinary trauma teams in a southern African country. METHODS: From 2007 to 2009, an educational program for trauma, "Better and Systematic Team Training," (BEST) was implemented at all government hospitals in Botswana. The effects were assessed through interviews, a structured questionnaire, and physical inspections using the World Health Organization's "Guidelines for Essential Trauma Care." Data on human and physical resources, infrastructure, trauma administrative functions, and quality-improvement activities before and at 2-year follow-up were compared for all 27 government hospitals. RESULTS: A majority of hospitals had formed local trauma organizations; half were performing multidisciplinary trauma simulations and some had organized multidisciplinary trauma teams with alarm criteria. A number of hospitals had developed local trauma guidelines and local trauma registries. More equipment for advanced airway management and stiff cervical collars were available after 2 years. There were also improvements in the skills necessary for airway and breathing management. The most changes were seen in the northern region of Botswana. CONCLUSIONS: Implementation of BEST in Botswana hospitals was associated with several positive changes at 2-year follow-up, particularly for trauma administrative functions and quality-improvement activities. The effects on obtaining technical equipment and skills were moderate and related mostly to airway and breathing management.

Trauma care in Africa: a status report from Botswana, guided by the World Health Organization's "Guidelines for Essential Trauma Care".

BACKGROUND: Trauma represents a significant and increasing challenge to health care systems all over the world. This study aimed to evaluate the trauma care capabilities of Botswana, a middle-income African country, by applying the World Health Organization's Guidelines for Essential Trauma Care. METHODS: All 27 government (16 primary, 9 district, 2 referral) hospitals were surveyed. A questionnaire and checklist, based on "Guidelines for Essential Trauma Care" and locally adapted, were developed as situation analysis tools. The questionnaire assessed local trauma organization, capacity, and the presence of quality improvement activity. The checklist assessed physical availability of equipment and timely availability of trauma-related skills. Information was collected by interviews with hospital administrators, key personnel within trauma care, and through on-site physical inspection. RESULTS: Hospitals in Botswana are reasonably well supplied with human and physical resources for trauma care, although deficiencies were noted. At the primary and district levels, both capacity and equipment for airway/breathing management and vascular access was limited. Trauma administrative functions were largely absent at all levels. No hospital in Botswana had any plans for trauma education, separate from or incorporated into other improvement activities. Team organization was nonexistent, and training activities in the emergency room were limited. CONCLUSIONS: This study draws a picture of trauma care capabilities of an entire African country. Despite good organizational structures, Botswana has room for substantial improvement. Administrative functions, training, and human and physical resources could be improved. By applying the guidelines, this study creates an objective foundation for improved trauma care in Botswana.
