Operating room discharge after deep neuromuscular block reversed with sugammadex compared with shallow block reversed with neostigmine: a randomized controlled trial.

OBJECTIVE: To determine if reversing a deep or moderate block with sugammadex, compared with a shallow block reversed with neostigmine, reduces the time to operating room discharge after surgery and the time spent in the postanesthesia care unit. DESIGN: A randomized controlled trial. SETTING: Monocentric study performed from February 2011 until May 2012. PATIENTS: One hundred consenting women with American Society of Anesthesiologists grade I or II were randomized into 2 groups. INTERVENTION: Laparoscopic hysterectomy was performed under desflurane general anesthesia. For the neostigmine (N) group, 0.45 mg · kg-1 rocuronium was followed by spontaneous recovery. A 5-mg rescue bolus was administered only if surgical evaluation was unacceptable. At the end of surgery, 50 µg · kg-1 neostigmine with glycopyrrolate was administered. For the sugammadex (S) group, a higher intubating rocuronium dose (0.6 mg · kg-1) was followed by 5-mg boluses each time the train-of-four count exceeded 2. Sugammadex (2-4 mg · kg-1) was administered to reverse the block. All patients were extubated after obtaining a train-of-four ratio of 0.9. MEASUREMENTS: The duration between the end of surgery and operating room discharge and the time spent in the postanesthesia care unit. MAIN RESULTS: The time till operating room discharge was shorter and more predictable in group S (9.15±4.28 minutes vs 13.87±11.43 minutes in group N; P=.005). The maximal duration in group S was 22 minutes, compared with 72 minutes in group N. The time spent in the postanesthesia care unit was not significantly different (group S: 47.75±31.77 minutes and group N: 53.43±40.57 minutes; P=.543). CONCLUSION: Maintaining a deep neuromuscular block during laparoscopic hysterectomy reversed at the end of the procedure with sugammadex enabled a faster and more predictable time till operating room discharge than did the classical combination of a shallower block reversed with neostigmine.

Ovarian tissue cryopreservation followed by controlled ovarian stimulation and pick-up of mature oocytes does not impair the number or quality of retrieved oocytes.

BACKGROUND: The objective of this study was to evaluate the feasibility of fertility preservation in cancer patients by combined bilateral ovarian cortex cryopreservation and embryo freezing. METHODS: This was a cohort-controlled study in a university hospital center. Sixteen patients with a recent cancer diagnosis were included in the study. They all consented to fertility preservation by a combined technique: ovarian tissue cryopreservation (OTC) followed by ovarian stimulation for in vitro fertilization (IVF) and embryo freezing. The control group included 100 women of the same age undergoing IVF for male factor infertility. RESULTS: The mean number of metaphase II oocytes was 8.3 per patient (±7.7) and was not statistically different from the control group (8.1 ± 5.6). The mean number of good quality embryos obtained was not statistically different in the 2 groups (4.2 versus 4.4). CONCLUSION: OTC before embryo freezing does not impair the number or quality of cryopreserved embryos, but increases fertility preservation potential.

Deep neuromuscular block improves surgical conditions during laparoscopic hysterectomy: a randomised controlled trial.

BACKGROUND: The benefit of inducing deep neuromuscular block to improve laparoscopic surgical conditions is controversial. OBJECTIVE: The goal of this study was to determine the depth of neuromuscular block needed to guarantee excellent operating conditions during laparoscopic hysterectomy. DESIGN: A randomised controlled trial. SETTING: A single-centre study performed between February 2011 and May 2012. PATIENTS: One hundred and two women of ASA physical status 1 or 2 gave consent to participate and were allocated randomly to one of two groups. INTERVENTION: Under desflurane general anaesthesia, patients in Group S (shallow block), neuromuscular blockade was induced by administration of rocuronium 0.45 mg  kg-1 followed by spontaneous recovery or a rescue bolus dose of 5  mg if surgical conditions were unacceptable. In Group D (deep block), neuromuscular block was induced by administration of rocuronium 0.6 mg  kg-1 and maintained by bolus doses of 5  mg if the train-of-four count exceeded two, using adductor pollicis electromyography. MAIN OUTCOME MEASURES: With a stable pneumoperitoneum (13 mmHg), the surgeon scored the quality of the surgical field every 10  min as excellent (1), good but not optimal (2), poor but acceptable (3) or unacceptable (4). The groups were compared using the Cochran-Armitage trend test. The level of neuromuscular blockade was recorded each time the surgical field score exceeded 1. RESULTS: For groups S and D, respectively, the maximum surgical field scores were 1 in 21 and 34 patients, 2 in 11 and 11 patients, 3 in 4 and 5 patients and 4 in 14 and 0 patients. A trend towards higher scores was demonstrated in group S (P < 0.001). Surgical field scores of 2, 3 and 4 occurred only when the train-of-four count was at least 1, 2 and 3, respectively. CONCLUSION: Inducing deep neuromuscular block (train-of-four count <1) significantly improved surgical field scores and made it possible to completely prevent unacceptable surgical conditions.

Laparoscopic repair of post-cesarean section uterine scar defects diagnosed in nonpregnant women.

Herein we describe laparoscopic repair of uterine scar defects after cesarean section and pregnancy outcomes in a series of 13 patients. Defects and the residual anterior uterine wall were evaluated using ultrasound and magnetic resonance imaging (MRI). Patients' clinical symptoms were recorded. Pregnancy outcomes were investigated after laparoscopic surgical repair. Intervention included laparoscopic repair of the defect, including excision of fibrotic tissue and laparoscopic closure of the anterior uterine wall. The defect was completely corrected using this technique in all 13 patients. Four patients became pregnant spontaneously, 3 delivered via cesarean section between 38 and 39 weeks, and 1 is currently pregnant. Evaluation of uterine scar defects after cesarean section can be performed using ultrasound and MRI, and the defect can be repaired via laparoscopy, with reproducible postoperative anatomic and functional outcomes.
