Ultrasound Subcostal Approach Transversus Abdominis Plane Block in Morbidly Obese Patient

Abstract

As general population of obese patients in Malaysia rapidly increases, more obese patients are requiring anaesthesia for various operative procedures. Obesity is associated with anatomical and physiological differences and co-morbidities that influence on the choices of anaesthesia care. A surgical case with general anaesthesia is used as a basis of discussion. A 37-year-old female, history of untreated hypertension and gastrooesophageal reflux disease (GORD), BMI of 41 admitted for laparoscopic cholecystectomy for symptomatic cholelithiasis under general anaesthesia. She presented with pain at the upper right abdomen and associated with bloated abdomen, nausea and vomiting after intake of meals. General anaesthesia and right ultrasound-guided transversus abdominis plane (TAP) block for abdominal wall blocks via subcostal approach was performed. Operation was removal gallstones in the common bile duct via laparoscopic approach. Post operation patient was extubated successfully. She was prescribed paracetamol 1g 4 hourly and started on fentanyl patient-controlled analgesia (PCA) for next 2 days. In this case report, there is the description of the application of TAP block which when used in obese abdominal surgical procedure, can provide excellent postoperative pain relief, early mobilization and recovery.
