[The model of the Niguarda Hospital Trauma Team in Milan]. / Il modello organizzativo del Trauma Team dell'Ospedale Niguarda di Milano.

The aim of this work was to describe the model and clinical results obtained by the Niguarda Trauma Team referral center for major trauma, in Milan. The Trauma Team is organized as a trauma service, where general surgeons, anesthesiologists, orthopedic surgeons and neurosurgeons work on a 24 hour rotation. When not in duty in the rotations, specialists work in their specific elective activities. The director of the Trauma Team has the responsibility for discussion and application of protocols, clinical assistance, quality assessment and training. The results of 1334 consecutive cases of major trauma during a 51 month period were reviewed using the trauma registry. 39% overtriage, which increased over the years, and 1.12% undertriage were recorded. Mortality of patients with injury severity scores > 15 was 21%, with a progressive decrease over the years. Blunt trauma accounted for 91.75% and were road-related in most cases. Skeletal injuries were the most frequent findings, but brain and thoraco-abdominal injuries were associated with a higher risk of death. 1476 surgical procedures (16.93% general surgery and 111 interventional angiographic studies) were performed. Quality assessment revealed a significant decrease in preventable deaths within the first 72 hours, after excluding patients admitted in extremis. The results presented in this study demonstrate the possibility of realising a model of organized trauma care in an emergency department in Italy, with patient outcomes comparable to those obtained in Trauma Center in other countries.

[Liver trauma: experience in the management of 252 cases]. / I traumi epatici: esperienza di trattamento di 252 casi.

The treatment of liver traumas has evolved considerably over recent decades with the possibility of non-operative management and arteriographic embolisation for selected patients in haemodynamically stable conditions. The aim of the study was to compare two periods with different approaches to the management of blunt or penetrating liver injuries. From January 1989 to October 2004, 252 patients were admitted to the emergency surgery department of Niguarda Hospital in Milan for liver traumas. Hepatic lesions accounted for 66% of abdominal lesions due to trauma and were classified according to the Organ Injury Scaling system. Abdominal ultrasound and CT scans were used to investigate the injuries. The study consisted of two periods: during the first period (1989-1993) surgery was the only treatment for trauma-induced hepatic lesions of any grade. Damage control surgery was employed for unstable patients undergoing laparotomy. From 1994 on, grade 1-2 injuries in patients with haemodynamically stable conditions were treated by non-operative management and grade 3 injuries by embolisation. In this second period only unstable patients with active bleeding or haemoperitoneum >500 ml with grade 3-5 injuries underwent laparotomy. The overall mortality for liver traumas was 27% (68/252) and was intraoperative in 97% of cases (66/68). Deaths were due to liver haemorrhage in 30 cases and to bleeding from extrahepatic or extra-abdominal injuries in the other 38 cases. Liver trauma was therefore directly responsible for mortality in as many as 12% of cases (30/252). The present study analysed two periods characterised by different approaches to the management of liver trauma. In the first period, laparotomy was the only choice, whereas subsequently non-operative management came to play an important role in haemodynamically stable patients and proved to be a safe method in selected cases. Major liver resections are seldom indicated in liver injuries. Damage control surgery has been practised since the first period and, before any surgical manoeuvres are performed, still represents a valuable tool to guarantee haemodynamic stability, which is the crucial factor for the outcome of liver resections for trauma.
