Summary Background Severe head injury is known to be a major cause of early mortalities and morbidities. Patients' long-term outcome after acute care, however, has not been widely studied. We aim to review the outcome of severely head-injured patients after discharge from acute care at a designated trauma center in Hong Kong. Materials and methods This is a retrospective study of prospectively collected data of patients admitted with severe head injuries between 2004 and 2008. Patients' functional status post-discharge was assessed using the Extended Glasgow Outcome Score (GOSE). Results Of a total of 1565 trauma patients, 116 had severe head injuries and 41 of them survived acute hospital care. Upon the last follow-up, 23 (56.1%) of the acute-care survivors had improvements in their GOSE, six (11.8%) experienced deteriorations, and 12 (23.5%) did not exhibit any change. The greatest improvement was observed in patients with GOSE of 5 and 6 upon discharge, but two of the 16 patients with GOSE 2 or 3 also had a good recovery. On logistic regression analysis, old age and prolonged acute hospital stay were found to be independent predictors of poor functional outcome after a mean follow-up duration of 42 months. Conclusion Multidisciplinary neurorehabilitation service is an important component of comprehensive trauma care. Despite significant early mortalities, a proportion of severely head-injured patients who survive acute care may achieve good long-term functional recovery.

Background To review currently available evidence on the use of adjuvant therapy to reduce the formation of postoperative intra-abdominal adhesions. Methods A search on Pubmed and the Cochrane library was undertaken using the keywords “abdominal”, “adhesion”, “postoperative”, “prevention” and “reduction”. Only randomised controlled trials, prospective non-randomised controlled studies and review articles published in the English language between 1990 and 2006 were included. Results Two prospective non-randomised controlled studies and 18 randomised controlled trials were included in this review. Adjuvant therapies reviewed included pharmacological agents (streptokinase, recombinant tissue plasminogen activator, vitamin E antioxidant molecules), and mechanical barriers (hyaluronic acid barriers, oxidised regenerated cellulose barriers, nanofibrous barriers and collagen foils). Hyaluronate/carboxymethylcellulose-based bioresorbable membrane (Seprafilm) appeared to be the most efficacious in reducing adhesion formation as well as decreasing the incidence of adhesion obstruction requiring reoperation in clinical studies. Drawbacks to the use of Seprafilm include high cost and complications such as haemorrhage and poor wound healing. Conclusions Only a limited number of adjuvant treatment methods are currently available for the reduction of postoperative adhesions. Seprafilm has been proven to be the efficacious method to reduce adhesions. Investigations into the novel therapies are showing promising results in experimental studies and clinical studies before their wider application.
