Observational study on the accuracy and speed of ultrasound guided transversus abdominis plane block with two different monitor positions

Abstract

Aim of the study is to analyse the accuracy and speed of ultrasound guided transversus abdominis plane block with two different monitor positions. Materials and Methods: Prospective observational study was conducted after institutional hospital ethics committee. Twenty four male patients posted for open inguinal hernia repair posted under spinal anaesthesia were selected and divided randomly into two groups and at the end of surgery USG TAP block was given. Group I -USG monitor was kept in line, whereas in Group II -USG monitor was kept in perpendicular to the participant. Twelve anaesthetists who had performed more than 20 procedure were selected and they performed one procedure in each group. History of back pain and neck pain was elicited and any discomfort during procedure was recorded. Accuracy of USG image was recorded. Time taken for the procedure was recorded for both groups. Result: Twelve anaesthetists were selected for this prospective study. Time taken to perform USG TAP in Group I vs Group II was (69.08 ± 8.19 s vs 80.16 ± 4.84s). Difference was statistically significant (p<0.001). Needle placement was significantly more accurate when anaesthetists had the monitor in front of them than to the side (Score was 15 vs 24). Out of 12 anaesthetists, 4 had history of neck pain previously and one was taking treatment for the same. When performed in Group I they had no discomfort but when performed in Group II, anaesthetists with positive history had discomfort during the procedure. Conclusion: It was concluded that the performance of USG TAP block was comfortable and more accurate and the procedure time was shorter, if the monitor was kept in line of the sight of the operator.

“…When MAP >80 mmHg, anesthetic drugs shall be added according to the intraoperative conditions; when MAP <60 mmHg, ephedrine shall be given appropriately to raise blood pressure. Inhalation of sevoflurane was stopped when the arthroscopy was completed and the wound was sutured [ 19 ]. Laryngeal mask removal criteria are as follows: the patient being awake; no obvious edema in head, neck, or upper limbs; spontaneous breathing tidal volume > 5 ml/kg, swallowing reflex recovery, and spontaneous lifting time > 5 s. Patients with HR < 50 times/min were given atropine symptomatic treatmentas needed.…”
