BACKGROUND: In mammals, homeostasis and survival are dependent on effective trans-membrane movement of ions and enzyme function, which are labile to extreme acid-base changes, but operate efficiently within a narrow regulated pH range. Research in patients demonstrating a pH shifts outside the narrow regulated range decreased the cardiac output and systemic vascular resistance and altered the oxygen binding to haemoglobin. These cardiopulmonary observations may be applicable to the risks associated with anaesthesia and performance of wildlife ungulates on game farms...

INTRODUCTION: Percutaneous Nephrolithotomy (PCNL) is the treatment modality used for the extraction of large renal stones, or multiple calculi or stones resistant to shock wave lithotripsy. The General Anaesthesia (GA) is the standard modality for PCNL. However, few studies conclude that Spinal Anaesthesia (SA) can be an alternative method of anaesthesia with similar incidence of complications. AIM: In our study we evaluated the feasibility of spinal anaesthesia in terms of intraoperative and postoperative results in patients undergoing PCNL...

We wished to evaluate whether inhibition of the systemic inflammatory response by a single pre-operative dose of methylprednisolone reduced markers of early endothelial damage after fast-track total knee arthroplasty. We randomly allocated 70 patients undergoing elective unilateral total knee arthroplasty (1:1) to receive either pre-operative intravenous methylprednisolone 125 mg (methylprednisolone group) or isotonic saline (control group). All procedures were performed under spinal anaesthesia without a tourniquet, using a standardised multimodal analgesic regime...

BACKGROUND: Unintentional perioperative hypothermia causes serious adverse effects to surgical patients. Thermal suit (T-Balance(®) ) is an option for passive warming perioperatively. We hypothesized that the thermal suit will not maintain normothermia more efficiently than conventional cotton clothes when also other preventive procedures against unintentional hypothermia are used. METHODS: One hundred patients were recruited to this prospective, randomized trial...

: The anaesthetic management of patients with myopathies is challenging. Considering the low incidence and heterogeneity of these disorders, most anaesthetists are unfamiliar with key symptoms, associated co-morbidities and implications for anaesthesia. The pre-anaesthetic assessment aims at the detection of potentially undiagnosed myopathic patients and, in case of known or suspected muscular disease, on the quantification of disease progression. Ancillary testing (e.g. echocardiography, ECG, lung function testing etc...

BACKGROUND: Lignocaine is a local anaesthetic agent, which is also commonly used as a perioperative analgesic adjunct to accelerate rehabilitation and enhance recovery after surgery. Lignocaine's systemic effects on intraoperative haemodynamics and volatile anaesthetic requirements are not well explored. Therefore, we evaluated the effects of intravenous lignocaine on intraoperative volatile agent requirements and haemodynamics in patients undergoing major abdominal surgery. METHODS: We performed an analysis of 76 participants who underwent elective open radical retropubic prostatectomy...

BACKGROUND: Colorectal surgery leads to morbidity during recovery including pain and fatigue. Intravenous (IV) lignocaine (IVL) has both analgesic and anti-inflammatory effects that may improve post-operative pain and recovery. The aim of this review is to compare the effectiveness of IVL to other perioperative analgesia regimens for reducing pain and opioid consumption following colorectal surgery. METHODS: Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement, a literature search was conducted to identify randomized clinical trials that compared IVL with IV placebo or epidural anaesthesia in open or laparoscopic colorectal surgery...

Chronic postsurgical pain (CPSP) is a common and debilitating complication of major surgery. We undertook a pilot study at three hospitals to assess the feasibility of a proposed large multicentre placebo-controlled randomised trial of intravenous perioperative ketamine to reduce the incidence of CPSP. Ketamine, 0.5 mg/kg pre-incision, 0.25 mg/kg/hour intraoperatively and 0.1 mg/kg/hour for 24 hours, or placebo, was administered to 80 patients, recruited over a 15-month period, undergoing abdominal or thoracic surgery under general anaesthesia...
