Summary

This study will be held to assess the effect of minimal dose muscle relaxant on postoperative pulmonary function. The time to extubation in minutes will be the primary outcome as a clinical indicator of the return of muscle power. The extubation time will be defined as the time from injecting the muscle relaxant reversing agent given when regain the train of four (TOF) ratio to 0.9 till removal of endotracheal tube.

Intraoperative surgical conditions will be assessed in the form of surgeon satisfaction and the need for more muscle relaxant boluses. Postoperative complications as desaturation (peripheral oxygen saturation (Spo2) less than 90%), the need for re-intubation or ventilation support will be recorded. Patient lung will be assessed using ultrasound-based lung aeration score. Also, the diaphragmatic and intercostal muscle function will be assessed in the early postoperative period. Immediate postoperative pulmonary function tests will be evaluated using simple spirometer. Patients will be followed up for 28 days for detection of pulmonary complications.

Conditions

  • Muscle Relaxant

Interventions

DRUG

Atracurium Besylate regular dose

Intubating dose of muscle relaxant will be atracurium 0.5 mg/kg Maintenance doses of muscle relaxant will be given throughout the intraoperative period to maintain the Train-of-four values continuously less than 2

DRUG

Atracurium Besylate minial dose

atracurium boluses of muscle relaxant given only upon complain of the surgeon and after a bolus dose of propofol 0.5 mg/kg. When required, 20% of the initial dose of muscle relaxant will be provided as a bolus to achieve this goal
