NCT ID: NCT04850404 Not yet recruiting - Nerve Block Clinical Trials

Effect of the Sheath of Rectus Abdominis Block Combined With the Transverse Plane

Start date: July 31, 2021
Phase: N/A
Study type: Interventional

The situation of demand for surgical conditions is quite high when lymph node resection involved in the surgery type, especially abdominal aortic lymph node dissection, and commonly, the surgeons complained about the interference from the intestine which pushed the investigators to increase the level of neuromuscular blockade close to deep NMB. To avoid the application of deep NMB and promote good surgical conditions for laparoscopic gynecological surgery with lymph nodes resection, the investigators explored other preoperative ways to cooperate with surgeons more harmoniously. It's well known that epidural anesthesia and epidural anesthesia combined with spinal anesthesia have the effect of muscle relaxation which has been applied in clinical practice widely. One study indicated that the Transverse Abdominal Plane (TAP) block could change muscle thickness and achieve the effect of muscle relaxation. It leads investigators to a hypothesis that the sheath of rectus abdominis block combined with transverse abdominal plane block may suppress the signal transmission of abdominal nerve, and may be beneficial to improve surgical conditions.

NCT ID: NCT03170661 Completed - Surgical Conditions Clinical Trials

Effect of Deep Versus Moderate Neuromuscular Block During Sevoflurane Anesthesia on Intraoperative Surgical Conditions.

BLISS4
Start date: June 14, 2017
Phase: Phase 4
Study type: Interventional

A deep neuromuscular block (NMB) is often associated with improved surgical conditions especially in laparoscopic surgery. We previously showed that deep NMB is superior to a moderate NMB under propofol anesthesia. However, this may not apply to sevoflurane anesthesia and sevoflurane by itself produces some degree of muscle relaxation. We therefore plan to investigate the effect of deep NMB on surgical conditions under sevoflurane anesthesia maintenance.

NCT ID: NCT02553629 Recruiting - Surgical Conditions Clinical Trials

Effect of Deep Neuromuscular Block on Surgical Conditions in Morbidly Obese Patients

BLISS3
Start date: September 2015
Phase: Phase 4
Study type: Interventional

This is a randomized control trial (RCT) that studies the surgical conditions during moderate and deep neuromuscular blockade in 100 morbidly obese patients receiving elective laparoscopic surgery for bariatric surgery.

NCT ID: NCT02079337 Completed - Clinical trials for Neuromuscular Blockade

Validation of Subjective Rating Scales Used to Assess Surgical Conditions in Abdominal Surgery

Start date: November 2013
Phase: Phase 4
Study type: Interventional

Use of neuromuscular blockade (NMB) may improve the surgical work space in patients scheduled for laparoscopic surgical cases (e.g. hysterectomy, ovarian cystectomy, myomectomy). Clinical studies investigating this question often use a numerical or verbal rating scale for subjective evaluation of the surgical workspace. However, no good subjective rating scale have been developed or validated. Neither have possible inter-individual differences in use of such subjective scales been described. Purpose: The aim of this study is to validate different subjective rating scales to determine which scale is most useful among surgeons.

NCT ID: NCT01748643 Completed - Obesity Clinical Trials

CURES: The Effect of Deep Curarisation and Reversal With Sugammadex on Surgical Conditions and Perioperative Morbidity

CURES
Start date: April 2013
Phase: Phase 4
Study type: Interventional

The purpose of this study is to investigate if a deep neuromuscular block with a continuous infusion of rocuronium titrated to a post-tetanic count (PTC) of 1-2 responses combined with reversal of neuromuscular blockade with sugammadex results in improved surgical conditions for the surgeon and/or improved post-operative respiratory function for the patients as compared to a standard technique with an intubation dose of rocuronium and top-ups as needed to maintain a neuromuscular blockade with a TOF count of 1-2 and reversal of neuromuscular blockade with neostigmine/glycopyrrolate. Furthermore, we want to investigate the effect of pneumoperitoneum, and NMB with rocuronium and reversal with sugammadex or neostigmine/glycopyrolate on cerebral tissue oxygenation.
