Dermot J Kelly, Sinéad M Farrell
More than 26 million Americans suffer with cataracts, and with 3.6 million cataract extractions performed annually in the United States, it is the most common surgical procedure. The integrity of the delicate structures of the eye that mediate vision is dependent on the intraocular pressure (IOP). Yet, IOP acts to compress the vessels within the globe-akin to a Starling resistor-and is a key component that determines the ocular perfusion pressure, defined as the difference between arterial pressure and IOP...

BACKGROUNDS AND OBJECTIVE: Some studies have shown that deeper anesthesia is more effective on postoperative analgesia and reduces the need for sedative drugs. This study sought to investigate the effect of depth of anesthesia on postoperative pain in laparoscopic cholecystectomy. MATERIALS AND METHODS: In this double-blind clinical trial, 60 patients undergoing laparoscopic cholecystectomy were randomly divided into two groups: low bispectral index (L-BIS=35-44) and high bispectral index (H-BIS=45-55)...

BACKGROUND: Laparoscopic radical prostatectomy induces hemodynamic changes that have been supposed due to autonomic nervous system activity. The aim of this study is to measure the sympathetic and vagal modulation on hemodynamic response to steep Trendelenburg and pneumoperitoneum for laparoscopic surgery. METHODS: Autonomic nervous system modulation was assessed noninvasively through heart rate variability and arterial pressure variability analysis in patients undergoing elective laparoscopic radical prostatectomy and in awake volunteers during head-down tilt...

BACKGROUND: GABA (γ-aminobutyric acid) is the primary inhibitory neurotransmitter in the CNS and well-known target for general anesthetics. In addition, the dysregulation of GABA could be involved in the etiology of MDD. In this study, we aimed to determine whether MDD has any effect on anesthetic requirement measured by bispectral index (BIS). METHODS: This study was designed as a prospective, observational study, registered ANZCTR (ACTRN12616001295437), with institutional review board approval and written informed consent...

PURPOSE: Intraocular pressure (IOP) increases in patients in a steep Trendelenburg position during robotic-assisted laparoscopic radical prostatectomy (RALP). We hypothesized that a steep Trendelenburg position during RALP, an unusual systemic condition involving a transiently increased IOP, may induce ocular pathology that can be detected by detailed evaluations long after the surgery. This study aims to explore ocular structural and functional parameters in patients before and in the long term after the surgery...

REVIEW
Marron Wong, Stephanie Morris, Karen Wang, Khara Simpson
In this review, we examine the evidence behind non-opioid medication alternatives, peripheral nerve blocks, surgical techniques, and postoperative recovery protocols that can help minimize and effectively treat postoperative pain after minimally invasive gynecologic surgery (MIGS). Due to the depth and heterogeneity of the data, a narrative review was performed of reported interventions. A comprehensive review was performed of Pubmed, EMBASE, and the Cochrane Database with a focus on randomized controlled trials (RCT)...

BACKGROUND: We aim to investigate whether intraoperative use of methylprednisolone could affect the duration of rocuronium-induced neuromuscular blockade. METHODS: A double blind, randomized, placebo-controlled trial was conducted. A total of 136 patients underwent gynecologic laparoscopic surgery were randomly divided into 3 groups: pregroup, receiving intravenous injection of methylprednisolone (40 mg) 30 minutes before induction of anesthesia; postgroup, receiving intravenous injection of methylprednisolone (40 mg) immediately after induction of anesthesia and intubation; and control group, receiving intravenous injection of normal saline...

OBJECTIVE: In laparoscopic adnexal surgery the conventional method of removing a mass from the abdominal cavity in Finland is through a 10-mm-wide lateral abdominal port. The larger the lateral trocar, the greater the risk of pain, complications and delayed recovery. Here, we assumed that adnexal mass removal through a 10-mm umbilical port together with 5-mm side trocars would decrease the postoperative need of analgesics when compared with removal through a 10-mm lateral abdominal port...

Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml(-1) mixed with 0.5 ml of fentanyl 50 μg ml(-1). Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery...

BACKGROUND: The effect of positive end-expiratory pressure (PEEP) has been studied in detail after induction of general anesthesia especially in obese individuals. However, sparse information can be gathered from the literature regarding its effect when applied at the time of induction and the time of onset of its effect. Thus, this study was planned to assess the effect of PEEP when applied for a single minute in morbidly obese patients. MATERIALS AND METHODS: This was a randomized prospective study comprising seven morbidly obese patients (body mass index ≥40 kg/m(2))...
