This study compares surgeon's satisfaction of operating conditions and patient's satisfaction following laparoscopic gynecological surgeries in two groups of patients, half of whom will receive deep neuromuscular blockade and the other half, moderate neuromuscular blockade.
Deep neuromuscular blockade in anesthesia has been shown to improve operating conditions in retroperitoneal surgeries, while there is minimal evidence regarding this method in laparoscopic gynecological procedures.The advantage of improving surgical conditions with a deep neuromuscular blockade in laparoscopic surgery may however lead to a delayed neuromuscular recovery and hence a delay in turnover of patients.
Rocuronium will be used for muscle relaxation in order to achieve the necessary depth of neuromuscular blockade. Sugammadex is a modified cyclodextrin that forms complexes with rocuronium, reducing free plasma concentrations of rocuronium and reversing its neuromuscular blocking action from any depth.
The use of rocuronium will therefore aid in achieving a deep neuromuscular blockade which the investigators postulate will improve surgical conditions and the reversal with sugammadex will ensure a rapid recovery thereafter.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| deep neuromuscular blockade | Experimental | Rocuronium will be administered to achieve PTC 1-2 throughout surgery. |
|
| moderate neuromuscular blockade | Active Comparator | Rocuronium will be administered to achieve TOFC 2 throughout surgery |
|

|---|---|---|---|---|
| Deep neuromuscular blockade | Drug | Deep neuromuscular blockade attained during surgery using Rocuronium 0.6mg/kg at induction of anesthesia with intermittent boluses of 0.15 - 0.2 mg/kg to maintain a Post Tetanic Count (PTC) of 1-2 throughout surgery.

| Measure | Description | Time Frame |
|---|---|---|
| Deep block versus Moderate block: Impact on surgical satisfaction | The surgeon will be required to score the quality of operating conditions every 15 minutes from 1st visualisation of peritoneal cavity until the removal of laparoscopes at the end of surgery. | Every 15 minutes from first laparoscopic view till the removal of laparoscopes at the end of surgery or up to 8 hours from 1st score. |
| Measure | Description | Time Frame |
|---|---|---|
| Deep block versus Moderate block: Patient satisfaction score | A blinded recovery nurse will administer Patient Satisfaction Questionaire | Post Anesthetic Recovery Score done at half hour from time of arrival at PACU and patient deemed fit for discharge up to 2 hours from time of arrival at PACU |
| Deep block versus Moderate block: Pain score |
