Background: We aimed to evaluate the evolution and implementation of the massive transfusion protocol (MTP) in an urban level 1 trauma centre. Most data on this topic comes from trauma centres with high exposure to life-threatening haemorrhage. This study examines the effect of the introduction of an MTP in an Australian level 1 trauma centre. Methods: A retrospective study of prospectively collected data was performed over a 14-year period. Three groups of trauma patients, who received more than 10 units of packed red blood cells (PRBC), were compared: a pre-MTP group (2002–2006), an MTP-I group (2006–2010) and an MTP-II group (2010–2016) when the protocol was updated. Key outcomes were mortality, complications and number of blood products transfused. Results: A total of 168 patients were included: 54 pre-MTP patients were compared to 47 MTP-I and 67 MTP-II patients. In the MTP-II group, fewer units of PRBC and platelets were administered within the first 24 h: 17 versus 14 (P = 0.01) and 12 versus 8 (P < 0.001), respectively. Less infections were noted in the MTP-I group: 51.9% versus 31.9% (P = 0.04). No significant differences were found regarding mortality, ventilator days, intensive care unit and total hospital lengths of stay. Conclusion: Introduction of an MTP-II in our level 1 civilian trauma centre significantly reduced the amount of PRBC and platelets used during damage control resuscitation. Introduction of the MTP did not directly impact survival or the incidence of complications. Nevertheless, this study reflects the complexity of real-life medical care in a level 1 civilian trauma centre.

Background and purpose — Anterior knee pain is common after tibial nailing. Its origin is poorly understood. Injury of the infrapatellar nerve is a possible cause. In this randomized controlled trial we compared changes in knee pain after an infrapatellar nerve block with lidocaine or placebo in patients with persistent knee pain after tibial nailing. Patients and methods — Patients with chronic knee pain after tibial nailing were randomized to an infrapatellar nerve block with 5 ml 2% lidocaine or placebo (sodium chloride 0.9%), after which they performed 8 daily activities. Before and after these activities, pain was recorded using a numeric rating scale (NRS; 0–10). Primary endpoint was the change in pain during kneeling after the infrapatellar nerve block. Secondary outcomes were changes in pain after the nerve block during the other activities. Results — 34 patients (age 18–62 years) were equally randomized. A significant reduction of the NRS for kneeling pain with an infrapatellar nerve block with lidocaine was found compared with placebo (–4.5 [range –10 to –1] versus –1 [–9 to 2]; p = 0.002). There were no differences between the treatments for the NRS values for pain during other activities. Interpretation — Compared with placebo, an infrapatellar nerve block with lidocaine was more effective in reducing pain during kneeling in patients with chronic knee pain after tibial nailing. Our findings support the contention that kneeling pain after tibial nailing is a peripheral nerve-related problem.
