High-grade renal trauma in children and adolescents can be successfully managed non-operatively

BACKGROUND

This paper reviews our experience with management of renal injuries in children and adolescents with a focus on the outcome of non-operative management (NOM).

METHODS

Retrospective review of the clinical characteristics, injury grade (I-III, low grade and IV and V high grade), management and outcomes of children ≤ 18 years old with renal trauma presenting to a major trauma centre in South Africa between December 2012 and October 2020.

RESULTS

Sixty-one children with a renal injury were identified with a median age of 13 (range 0-18) years. Forty-five were boys; blunt and penetrating mechanisms of trauma were sustained by 55 (90%) and six (10%) children, respectively. The median American Association for the Surgery of Trauma (AAST) grade of renal injury was 3 (range 1-5): this included eight (13%) with grade I, six (10%) with grade II, 17 (28%) with grade III, 20 (46%) with grade IV and 10 (16%) with grade V injuries. Forty children (66%) were successfully managed non-operatively and 21 required a laparotomy; of these six (28%) required nephrectomy. The overall renal salvage rate was 55/61 (90%). Children who required laparotomy were significantly more likely to have sustained a penetrating mechanism of injury (24% vs 2%) and have greater length of hospital stay (median 9 vs 3 days) compared to children managed non-operatively (p < 0.05). Children who underwent a nephrectomy had a significantly greater length of hospital stay (median 9 vs 4 days, p = 0.03); however, their demographics, outcomes developed complications. Two children (3%) died; one managed non-operatively and one with a laparotomy.

CONCLUSION

Paediatric renal trauma can be successfully managed non-operatively in over two-thirds of cases in this middle-income country. High grade of renal injury does not absolutely predict need for surgery or nephrectomy and can be managed non-operatively.

Management of penetrating thoracic trauma with retained knife blade: 15-year experience from a major trauma centre in South Africa

INTRODUCTION

This study reviews our experience with the management a retained knife in the setting of thoracic stab wounds.

METHODS

A retrospective study was conducted at a major trauma in South Africa over a 15-year period from January 2004 to December 2018.

RESULTS

There were 40 patients, of whom 37 were males (93%). Median age was 24 years; 78% of cases (31 of 40) were a retained knife and 23% (9 of 40) were a retained blade. The locations of the stab wounds were 19 (48%) anterior and 21 (53%) posterior. Plain x-ray was performed in 85% (34) of patients and computed tomography angiography was performed in 85% (34). Six patients had haemodynamic instability and were expedited to the operating room without further imaging. Three of these had cardiac tamponade and three a massive haemothorax. Simple extraction and wound exploration were performed in 58% (23 of 40) of cases and the remaining 43% (17 of 40) required operative exploration and extraction. The operative approach was anterolateral thoracotomy in nine cases, posterolateral thoracotomy in four and median sternotomy in three cases. One patient required extraction and concurrent vertebral laminectomy due to cord compression. Twelve patients (30%) experienced complications (nine wound sepsis and three hospital-acquired pneumonia). There was one mortality (3%). The median length of hospital stay was 6 days.

CONCLUSION

Uncontrolled extraction of a retained thoracic knife outside the operating room must be avoided. An unstable patient should proceed directly for operative exploration. For stable patients, cross-sectional imaging will allow for planned extraction in operating room.

The correlation between full moon and admission volume for penetrating injuries at a major trauma centre in South Africa

BACKGROUND

The possible effect of full moon on admission volume of trauma centres is a well-mentioned phenomenon that has been perpetuated worldwide. We aimed to review the correlation between full moon and admission volume and to interrogate any possible relationship on admission for penetrating trauma.

METHODS

A retrospective study from 2012 to 2018 at Pietermaritzburg Metropolitan Trauma Service (PMTS), South Africa.

RESULTS

A total of 8 722 patients were admitted. Eighty-three per cent (7 242/8 722) were male and the mean age was 29 years. The total number of days during the study period was 1 953, 66 of which were 'full moon' (FM) days and 1 887 were 'non-full moon' (NFM) days. There was no significant difference between gender or age distribution. The mean number of admissions per day on FM days compared with NFM days was not significant (4.1 vs 4.5, p = 0.583). A total of 3 332 patients with penetrating trauma were admitted. This constituted 42% (113/271) of admission on FM days and 38% (3 219) on NFM days, which is not statistically significant (p = 0.229). Subgroup analysis did not demonstrate any significant difference between the number of stab wounds - 28% (77/113) vs 25% (2 124/3 219) - or gunshot wounds - 13% (16/113) vs 12% (990/3 219) - between FM and NFM days.

CONCLUSION

The correlation between full moon and trauma admission is unfound in our setting. The perpetuating notion that 'it must be full moon tonight' is likely to be an urban myth with no scientific evidence for such a claim.
