Abstract
Morbid obesity is associated with various pathophysiological changes which affect the outcome of anaesthesia and surgery. So it's challenging to give anaesthesia to such patients. We present a 59-year-old adult morbidly obese, hypertensive, diabetic female with hypothyroidism operated for proximal humerus fracture and now presented with non-union of fracture, requiring percutaneous injection of bone marrow aspirate from the iliac crest to the site of non-union. The patient was extremely anxious and refused to undergo the procedure under local anaesthesia or sedation and demanded anaesthesia. Given her comorbidities general anaesthesia (GA) was avoided and the procedure was accomplished using Ultrasound (USG) guided Transversus abdominis plane (TAP) block and Lateral Femoral Cutaneous Nerve (LFCN) block for the bone marrow aspirate from the iliac crest and Intercostobrachial nerve block (T2) was given to prevent pain while injecting the aspirate into the non-union site. Dexmedetomidine and ketamine were given for deep level sedation and analgesia. TAP block and LFCN block is generally used for post-op analgesia but can be also used for surgical anaesthesia instead of General anaesthesia in specific scenarios. Its perioperative application and its potential use instead of GA have been discussed.
