A review of the complications encountered in a quaternary trauma intensive care unit in South Africa

Background: Due to the invasive nature required for support and multiple therapeutic interventions, critically ill patients are at high risk of complications unrelated to their underlying illness or injury. This audit aimed to describe the spectrum of complications in a trauma intensive care unit, to identify potential remedial interventions to improve quality of care and reduce morbidityMethods: Complications in the Trauma Intensive Care Unit at Inkosi Albert Luthuli Central Hospital are documented prospectively on a specific proforma. A 12-month audit was performed between 2012­2013. Complications were divided into septic and non-septic adverse events and the relationship to injury severity, time of onset and outcome were analysed.Results: Of 283 patients admitted during the study period, 77 (32.5%) suffered a total of 161 adverse events. Ninety-seven (60.2%) complications were sepsis-related and 64 (39.2%) were unrelated to sespis. Ventilator-associated pneumonia was the commonest septic event (38.1%) and extubation-related events the most frequent non-septic complication (45.3%). The number of complications ranged from one in the majority of patients (49.4%) to 6 (3.9%) in 3 patients. There was no significant difference in mortality between those with (24.7%) or without (17.4%) complications (p = 0.22) however, those with complications had a significantly longer length of ICU stay (p < 0.001).Conclusion: Complications are common in the critically injured who necessitate admission to an intensive care unit. The vast majority arise from infective causes, especially ventilator-associated pneumonia. Adverse events related to the endotracheal tube are the commonest non-infective events. The identification of these adverse events should prompt interventions aimed at reducing the incidence

Intra-abdominal injury identified by CTA in stable blunt polytrauma patients

Background: Patients with multiple injuries are a challenge to evaluate and to exclude abdominal injury, especially those who are intubated and sedated. Ultrasound is a screening tool and peritoneal lavage is unreliable. The aim of the study was to determine the incidence of intra-abdominal injury and describe the subsequent management after CT "panscan" in patients sustaining blunt trauma with injuries both above the thoracic and below the pelvic diaphragm. Methods: In a retrospective analysis anonymised patient data were extracted from a prospective ethics approved database of patients admitted to the level I Trauma Unit at Inkosi Albert Luthuli Central Hospital for the period from April 2007 to March 2011. Blunt polytrauma patients, aged 2 years and older with injuries above the diaphragm and below the pelvic floor were included, provided they were investigated by a full-body trauma Computed Tomography contrast study. Descriptive statistics were employed for all variables of interest, with counts/frequencies and associated percentages being reported. Results: Of 284 patients with injuries above the thoracic and below the pelvic diaphragm, 87 (30.6%) had intra-abdominal injury and 197 (69.4%) had no intra-abdominal injuries. Of those 87 patients, 54 (62.1%) were treated non-operatively and 33 (37.9%) were treated surgically with regard to their abdominal injuries. Twenty (22.9%) patients died, 4 due to intra-abdominal injuries and 16 due to of extra-abdominal injuries. Nine (45%) of the twenty patients who died were treated operatively for intra-abdominal injuries and the remaining 11 (55%) were treated non-operatively.Conclusion: Around thirty percent of patients with injuries above the thoracic and below the pelvic diaphragm had concomitant intra-abdominal injuries. Of those with abdominal injury, just over half required laparotomy. For haemodynamically stable patients CT scanning identified those who require surgical intervention and those who may be managed non-operatively, therefore liberal CT-scanning is advisable for this patient group

Elevated International Normalised Ratios Correlate with Severity of Injury and Outcome

Background. Haemorrhagic shock is the leading cause of preventable early deaths from trauma. Acute coagulopathy on admission to a trauma unit is associated with worse outcomes. The relationship of haemorrhage to early mortality remains consistent regardless of mechanism of injury. Haemorrhage and haemorrhagic shock are increasingly amenable to interventions that result in reductions in morbidity and mortality.Objectives. To assess the prevalence of coagulopathy in patients admitted to the level 1 trauma unit at Inkosi Albert Luthuli Central Hospital; Durban; South Africa; and correlate it with in-hospital mortality.Methods. A retrospective analysis of the first 1 000 patients admitted to the trauma unit during the years 2007 - 2011 was performed. The admission international normalised ratios (INRs) were correlated with Injury Severity Scores (ISSs) and in-hospital mortality. A multivariable Poisson model with robust standard errors was used to assess the relationship between coagulopathy and mortality after adjustment for the confounding influence of age and gender. The data were analysed using the R statistics program. Results.Of the 1 000 patients; 752 were male. There were 261 admissions directly from the scene and 739 inter-hospital transfers (non scene). The mean INRs among survivors for all; scene and non-scene patients were 1.33; 1.30 and 1.34; respectively; and those among non-survivors 1.92; 2.01 and 1.88; respectively (p0.001). The overall prevalence of coagulopathy was 48.7%; 46.9% in scene patients and 49.2% in non-scene patients. The mortality rate of scene patients with abnormal INR levels was 41.1% (adjusted relative risk (aRR) 3.59; 95% confidence interval (CI) 2.11 - 6.44; p0.001) v. 25.1% for non-scene patients (aRR 1.67; 95% CI 1.15 - 2.05; p
