Endocrine and oxidative stress characteristics in different anesthetic methods during pneumoperitoneum in dogs

AbstractGeneral anesthesia and pneumoperitoneum are two main components of laparoscopic surgery. The aim of this study was to evaluate the effects of anesthesia on endocrine and oxidative variables during pneumoperitoneum including as follows: triiodothyronine (T3), thyroxin (T4), cortisol, malondialdehyde (MDA), and total antioxidant capacity (TAC). Twenty mixed-breed adult dogs were randomly divided into four groups: propofol and mechanical ventilation (group P-M), propofol and spontaneous ventilation (group P-S), isoflurane and mechanical ventilation (group I-M), isoflurane and spontaneous ventilation (group I-S). The dogs were pre-medicated with acepromazine, morphine, and diazepam respectively. Anesthesia was induced by propofol in all the subjects. After tracheal intubation, anesthesia was maintained in P-M and P-S groups by intravenous propofol and in I-M and I-S groups by isoflurane in oxygen, while the subjects ’ lungs were mechanically ventilated in P-M and I-M groups. Pneumoperitoneum was induced in all subjects and intra-abdominal pressure (IAP) was maintained at 15 mmHg for 40 min. The concentrations of T3, T4, cortisol, MDA, and TAC were measured before and after the induction of anesthesia, 40  min after abdominal insufflation and 2, 4, 6, 12, 24, and 48 h postoperatively. There was no significant difference among four anesthetic groups in the concentrations of T3, T4, cortisol, and TAC during the sampling. Serum MDA level was signific...

ConclusionsThe PCV-VG mode of ventilation limited the peak inspiratory pressure, decreased the driving pressure and increased the dynamic compliance compared to VCV in obese patients undergoing laparoscopic hysterectomy. PCV-VG may be a preferable modality to prevent barotrauma during laparoscopic surgeries in obese patients.ResumoJustificativa e objetivosO objetivo deste estudo foi investigar a eficácia dos modos de ventilação garantida por volume controlado por pressão (PCV-VG) e ventilação controlada por volume (VCV) para manter pressões adequadas nas vias aéreas, ...

[Pelviureteric junction obstruction and crossing vessels: pro "vascular hitch"]. Aktuelle Urol. 2019 Nov 07;: Authors: Zahn K, Younsi NF, Stein R Abstract The vascular hitch procedure for pelviureteric junction obstruction caused by crossing lower-pole vessels is a controversial treatment option. Since this minimally-invasive technique has been introduced in patients with aberrant lower-pole vessels, multiple publications have reported successful short, intermediate and long-term outcomes. Success rates ofโ€Š>โ€Š90โ€Š% are similar to those of Anderson-Hynes pyeloplasty. In general, an ass...

Purpose of review The purpose of this review is to discuss the optimal use of neuromuscular blocking agents (NMBA) during ambulatory surgery, and to provide an update on the routine use of neuromuscular monitoring and the prevention of residual paralysis. Recent findings The number of major surgical procedures performed in ambulatory patients is likely to increase in the coming years, following the development of laparoscopic and thoracoscopic procedures. To successfully complete these procedures, the proper use of NMBA is mandatory. The use of NMBA not only improves intubating conditions but also ventilation. Recent ...

Authors: Yilmaz G, Akca A, Kiyak H, Salihoglu Z Abstract BACKGROUND: Optic nerve sheath diameter (ONSD) measurement with ultrasound has emerged as a simple, non-invasive and reliable surrogate of invasive intracranial pressure (ICP) measurement. Increase in ICP might lead to postoperative nausea and vomiting (PONV) and postoperative headache. Here, we aimed to evaluate the extent of change in ONSD, resulting from pneumoperitoneum (PP) and Trendelenburg (TP) position during the laparoscopic hysterectomy (LH), by using ultrasonographic ONSD measurement. We also aimed to investigate the relation of ONSD with PONV and ...

WeidlerAbstractBilateral gonadectomy was the historical recommendation for patients diagnosed with complete androgen insensitivity syndrome (CAIS) due to the perceived risk of malignancy in the gonads. However, new shared-decision making approaches are allowing patients to explore the option to defer surgery. Here we report two patients who presented with primary amenorrhea to their primary care provider (PCP). After imaging and karyotyping, these patients were d...
