Patients With Acute Hip Fractures Will Receive Either the PENG Block or no Block Respectively. (PENGBlock)
Evaluation of the PENG Block vs Placebo for Preoperative Pain Control in Hip Fractures in the Elderly - a Double-blinded Randomised Controlled Trial
Hip fracture pain is often severe and traditionally managed by systemic opioids which have increased risk of side effects in frail elderly patients. Inadequately controlled pain may lead to delirium which increases mortality and morbidity. The overall aim of this RCT is to investigate the potential for improved pain relief accomplished by the addition of the PENG block to current standard practice of pre-operative analgesia (systemic morphine), compared to the control group, which involves no block (operator will still go through the motion as if performing a block) plus standard pre-operative analgesia.
The investigator hypothesize that the addition of a single shot PENG block at the side of hip fracture in addition to traditional systemic morphine provides good preoperative pain relief on movement and reduces the need for breakthrough opioid requirements. The investigator hypothesize that the interventional group dynamic pain score assessed at 30 minutes after the block compared to control group dynamic pain score at 30 minutes after the "block" will be at least a 3 point difference between the 2 groups .

Detaljert beskrivelse
Specific Aim1: To determine difference in pain scores on movement (dynamic pain scores) in patients who receive the PENG block in the intervention group compared to no block in the control group at 30 minutes after performance of the block.
Specific Aim2: To determine if there is any difference in pain at rest between the intervention group and the control group, and if so, the magnitude of the difference in pain scores.
