Closed-wound negative pressure therapy dressing after loop ostomy closure: a retrospective comparative study.

Closed-wound negative pressure wound therapy (NPWT) dressings were recently introduced with the purpose to reduce incisional surgical site infections (iSSI) in high-risk wounds. The aim of this study was to compare iSSI rates in patients after ostomy closure with and without additional application of a closed-wound NPWT dressing. Single-center retrospective analysis of consecutive patients undergoing ileo- or colostomy closure over an 8-year period (January 2013-January 2021). Intradermal non-purse string technique with absorbable sutures were used in all patients. Since November 2018, all patients (study group) received a NPWT device for a maximum of 5 days postoperatively (PICO, SMITH AND NEPHEW). Primary outcome was iSSI rate within 30 days of surgery. SSI was defined in accordance with the Center of Disease Control (CDC) classification and included superficial and deep incisional SSI. Data was retrieved from the institutional enhanced recovery after surgery (ERAS) database, with standardized complication assessment by trained abstractors. In total, 85 patients (25%) in the study group were comparable with 252 (75%) patients in the control group regarding demographics (age, gender, body mass index, ASA score), ostomy type and anastomotic technique (all p > 0.05), but not wound contamination class (class III: 5% vs 0%, p < 0.001). Median time to NPWT removal was 4 (IQR 3-5) days. Incisional SSI were observed in 4 patients (4.7%) in the study group and in 27 patients (10.7%) in the control group (p = 0.097). These preliminary results suggest a potential benefit of systematic application of the NPWT device after loop ostomy closure. A randomized controlled study is needed.

[Pediatrics. The PAT: a simple and rapid tool for the assessment of the severely ill or injured child]. / Pédiatrie. 2. Le TEP: outil de triage recommandé pour l'évaluation de l'enfant gravement malade ou accidenté.

The Pediatric Assessment Triangle (PAT) has become the cornerstone for the assessment and treatment of a critically ill or injured infant/young child. Now incorporated to the PALS course, it can be taught to all levels of health care providers in charge of severly-ill children. The PAT is a rapid and simple observational tool suitable for pediatric assessment regardless of complaint or underlying diagnosis. It can be introduced in every emergency department, especially those having relatively infrequent encounters with very sick children. Implementation of such a tool needs formal theoritical and practical education skills, rapid availability of experienced pediatric seniors and spaces specifically intented for children.

[Acute respiratory distress syndrome in children]. / Le syndrome de détresse respiratoire aiguë (SDRA) chez l'enfant.

The acute respiratory distress syndrome (ARDS) encountered in a child may be either due to a primary lung infection or may be secondary to a systemic inflammatory response of varying origin. Therapy is based on: 1) the mechanical ventilation strategy aimed at maintaining the functional residual capacity by alveolar recruitment using positive end expiratory pressure and to limit secondary pulmonary lesions by using small tidal volumes, 2) prone positioning as soon as sufficient stability is achieved; 3) optimizing tissue oxygen delivery by cardiac support; 4) correction of any other organ dysfunction. If this conventional approach is not sufficient experimental therapies may be tempted given the vital risk. For instance inhaled nitric oxide and high frequency oscillation ventilation may be a valuable support. Newer techniques, such as partial liquid ventilation, are being developed and could become useful therapeutic options. After the acute phase a close medical follow-up is mandatory. Because of the possibility of a chronic respiratory insufficiency with negative consequences on the right ventricular function, these patients may need long term oxygen therapy and diuretics. Cardiac echography helps orientation in maintaining or discontinuing this long term therapy by estimating the arterial pulmonary pressure.
