RESUMO
This work focuses on a real-life patient transportation problem derived from emergency medical services (EMS), whereby providing ambulatory service for emergency requests during disaster situations. Transportation of patients in congested traffic compounds already time sensitive treatment. An urgent situation is defined as individuals with major or minor injuries requiring EMS assistance simultaneously. Patients are either (1) slightly injured and treated on site or (2) are seriously injured and require transfer to points of care (PoCs). This paper will discuss enhancing the response-time of EMS providers by improving the ambulance routing problem (ARP). A genetic based algorithm is proposed to efficiently guide the ARP while simultaneously solving two scenarios.

INTRODUCTION: Subarachnoid morphine is widely used for pain relief in enhanced recovery program after cesarean section in spite of its side effects. However, the role of TAP block is still controversial. The aim of our study was to compare the impact of these analgesic techniques (subarachnoid morphine and TAP block) on enhanced recovery after cesarean section. MATERIALS AND METHODS: In this randomized controlled trial, we included patients scheduled for cesarean delivery under spinal anesthesia. Patients were randomized in two groups. Group I: received spinal anesthesia with 100µg of subarachnoid morphine. Group II: received spinal anesthesia without subarachnoid morphine followed by an ultrasound-guided TAP block. We assessed the time required for mobilization, for re-establishment of gastrointestinal transit and for breast-feeding. RESULTS: TAP block allowed earlier postoperative mobilization. Time required for getting up was significantly lower in group II (9.4h versus 6.9h; P=0.024) as well as time required for walking (12.4h versus 7.4h; P=0.001). TAP block allowed earlier re-establishment of gastrointestinal transit (11.2h in group I versus 8.1h in group II; P<0.001). CONCLUSIONS: TAP block seems to be suitable with enhanced recovery programs.
