简要总结
Central neuraxialblocks (combined spinal epidural blocks) are one of the preferred techniques foranaesthetising patients posted for orthopaedic surgeries for fracture femur fixation. Positioning these patients for neuraxial blockadehowever is rendered very difficult due to the pain of fracture. Suboptimal positioning sometimes leads to prolongedduration and in some cases lead to block failure as well. It alsocauses severe pain and discomfort to the patients which may result in haemodynamicdistubances including tachycardia and hypertension.
Femoral nerve block has been shown to be an effectivemethod of analgesia for spinal positioning in patients with fractured femoral shaftand proximal femur fractures. Several drugsincluding opioids have also been employed for this purpose and had been comparedwith femoral nerve block.but use of opioids has disadvantages of causing drowsinessand respiratory depression. Paracetamol is a nonopioid analgesic and is one of thecommonly used analgesic agent that had been used in various acute pain conditionsincluding postoperative pain .Intravenous paracetamol is the formulation which ispreferred in the perioperative period due to its increased bioavailability and isalmost safe in all age groups and is easilyaccessible. The main advantage of paracetamol is that it is easilyadministrable as compared to blocks.In this study we like to compare the efficacyof femoral nerve block and intravenous paracetamol given in the preoperative period,in improving conditions of positioning required for cental neuraxial block.
Eventhough paracetamol has been studied as an analgesic in intraoperative and postoperativeperiod, its usefulness in the preoperative period for the purpose of providing analgesiafor patient positioning for central neuraxial block in patients with femur fracturehas not been studied. Intravenousparacetamol if it is found to be effective in providing adequate analgesia and providingoptimal conditions for patient positioningduring performance of central neuraxial block can be used routinely for this purposepreoperatively in patients with fracture femur posted for surgery

结局指标
主要结局
Comparison of analgesic efficacy of femoral nerve block versus intravenous paracetamol during positioning for central neuraxial block in patients with femur fractures
时间窗: VAS scores will be assessed during patient positioning for central neuraxial blockage
between group P(intravenous paracetamol) and group F( femoral nerve blockage ) using visual analogue pain Scale (VAS score).
时间窗: VAS scores will be assessed during patient positioning for central neuraxial blockage
次要结局
- Comparison of hemodynamic parameters(pulse rate and blood pressure)during the positioning of the patient in both groups.(During patient positioning for central neuraxial blockage)
- Comparison of the quality of patient position in likerts scale as perceived by the anaesthesiologist performing the central neuraxial block between both the groups.(During patient positioning for central neuraxial blockage)
- Comparison of the total time taken for performance of the block in both the groups.(Time taken for central neuraxial block will be compared)
- Comparison of the rescue fentanyl dose used during the procedure to alleviate the pain in both the groups.(if patient still has VAS score greater than 4 during positioning even after intravenous paracetamol(group P) or femoral nerve block(group F))
