PURPOSE: Minor hand surgeries can be done under field sterility in procedure rooms. Surgeons are still sceptical about the usage of wide awake local anaesthesia no tourniquet (WALANT) technique. They perceive that patients can tolerate tourniquet for a brief period while they perform minor surgeries under local anaesthesia (LA). We compared the perceived comfort experienced by patients during minor hand surgeries with WALANT and LA/tourniquet. We investigated the difference in preoperative preparation time, operating time and blood loss between the two groups...

BACKGROUND: Ultrasound-guided lumbar plexus blocks usually require confirmatory neurostimulation. A simpler alternative is to inject local anaesthetic inside the posteromedial quadrant of the psoas muscle under ultrasound guidance. OBJECTIVE: We hypothesised that both techniques would result in similar total anaesthesia time, defined as the sum of performance and onset time. DESIGN: A randomised, observer-blinded, equivalence trial (equivalence margin = 7...

Volatile agents are widely used to anaesthetise laboratory non-human primates as they allow a rapid induction and recovery as well as an easy adjustment of the anaesthesia plan. Desflurane is currently the volatile agent with the lowest solubility in blood, and hence enables the most rapid onset of anaesthesia and most rapid recovery. This study aimed to investigate the suitability of desflurane for maintenance of general anaesthesia in rhesus macaques undergoing elective experimental neurosurgery. Fourteen primates (five males and nine females) were sedated with ketamine (10 mg kg(-1)) and anaesthesia was induced with propofol (usually 8 mg kg(-1) IV)...

BACKGROUND: Developmental dysplasia of the hip (DDH) diagnosed in older postnatal children can be effectively treated by closed reduction (CR) alone. However, no prospective or comparative trial to explore the differential effectiveness of CR between non-walking and walking postnatal children has yet been reported. This study investigated the clinical and radiologic outcomes of CR in the age range of interest (12-18 months old) via a prospective trial and compared these results with those of a younger age group who also underwent CR...

Edwards' syndrome also known as trisomy 18 is a congenital disorder associated with cardiovascular issues including ventricular septal defect (VSD), atrial septal defect (ASD) and patent duct arteriosus (PDA). An emergency colostomy was performed on a neonate born with an imperforate anus. Pre-operative transthoracic echocardiography showed presence of VSD, a patent foramen ovale (PFO) or ASD. Even though the baby had a good general condition and optimal peripheral oxygen saturation (SpO2), during positive pressure ventilation, she suffered severe hypoxia (50% SpO2)...

Objective Although robotic thyroidectomy (RoT) is a minimally invasive surgery, percutaneous tunneling causes moderate to severe pain immediately postoperatively. We evaluated the efficacy of ketamine for postoperative pain management in patients following RoT. Methods Sixty-four patients scheduled for RoT were randomly divided into two groups. In the ketamine group (n = 32), ketamine was infused from induction of anaesthesia until the end of the procedure (0.15-mg/kg bolus with continuous infusion at 2 µg/kg/min)...

BACKGROUND: Cardiac output (CO) is an important haemodynamic parameter to monitor in patients during surgery. However, the majority of the techniques for measuring CO have a limited application in veterinary practice due to their invasive approach and associated complexity and risks. Transoesophageal echocardiography (TEE) is a technique used to monitor cardiac function in human patients during surgical procedures and allows CO to be measured non-invasively. This prospective clinical study aimed to compare the transoesophageal echocardiography using a transgastric view of the left ventricular outflow tract (LVOT) and the thermodilution (TD) technique for the assessment of CO during mean arterial pressure of 65-80 mmHg (normotension) and <65 mmHg (hypotension) in dogs undergoing elective surgery...

Background: Postoperative secondary hyperalgesia arises from central sensitization due to pain pathways facilitation and/or acute opioid exposure. The latter is also known as opioid-induced hyperalgesia (OIH). Remifentanil, a potent μ-opioid agonist, reportedly induces postoperative hyperalgesia and increases postoperative pain scores and opioid consumption. The pathophysiology underlying secondary hyperalgesia involves N-methyl-D-aspartate (NMDA)-mediated pain pathways. In this study, we investigated whether perioperatively infusing low-dose buprenorphine, an opioid with anti-NMDA activity, in patients receiving remifentanil infusion prevents postoperative secondary hyperalgesia...

BACKGROUND: Intravenous regional anaesthesia (IVRA) and hindfoot four-point nerve block anaesthesia (NBA) are recommended for local anaesthesia (LA) in the distal limb of dairy cows. Two studies were conducted to compare the efficacy, time until onset and stress responses to IVRA and NBA in dairy cows. In the first cross-over designed study, eight healthy unsedated German Holstein cows, restrained in lateral recumbency (LR) on a surgical tipping table, were treated with IVRA and NBA using procaine 2% as a local anaesthetic...

Objective: Several reports have shown the negligible adverse effects of low-dose remifentanil on the autonomic nervous system. We propose that the administration of low-dose remifentanil would be beneficial without adverse respiratory and hemodynamic effects. This study aimed to examine the effects of low-dose remifentanil on postoperative pain relief and heart rate variability (HRV) after surgery. Methods: In total, 20 patients, who underwent breast cancer surgery, were analysed for HRV in the post-anaesthesia care unit (PACU)...

Objective: Volatile anaesthetics can inhibit the bronchociliary clearence in a dose- and time-dependend way. Moreover, they can have potential mutagenic/carcinogenic effects under chronic exposure. A genotoxicity test -micronuclei assay- was carried out in nasal epithelial cells to analyze the genotoxic effect of sevoflurane in adult patients undergoing general anesthesia. Methods: In this study, micronucleus (MN) assay was conducted using nasal epithelial cells of 37 adult patients (age, 18-65 years) who underwent elective, minor, short surgical procedures under general anaesthesia with sevoflurane...

Volatile anaesthetic agents are a potential occupational health hazard to theatre and recovery staff. Operating theatres and anaesthetic rooms are required to be equipped with scavenging systems, but recovery units often are not. We compared exhaled, spectrophotometric sevoflurane and desflurane concentrations 15 cm from the mouth ('patient breathing zone') and 91 cm laterally to the patient ('nurse work zone') in 120 patients after tracheal extubation who were consecutively allocated to either ISO-Gard mask oxygen/scavenging or standard oxygen mask, 0 min, 10 min and 20 min after arrival in the theatre recovery unit...

Premise and Objective: Elective laparoscopic cholecystectomy (LC) has low risk for post-operative infectious complications; still most clinicians use persistent post-operative prophylactic antibiotics out of habit, tradition, or simply as defensive practice due to evolving medicolegal implications of a large number of surgeries being showcased as daycare or next day discharge procedures. This randomised prospective trial was done to test the need for such prophylaxis in cases of elective LC in a rural/semi-urban setting...

T Sivakumar, R A Amizhthu
Conventional open thyroidectomy is often associated with post-operative complications including nerve damage, voice disturbances, paraesthesias, adhesions and prominent scarring. Several endoscopic surgical techniques have been reported as alternatives to conventional thyroidectomy. Natural orifice transluminal endoscopic surgery is a promising approach which leaves no scar, produces few complications and affords faster discharge from care. Several studies have explored its utility in total thyroidectomy in patients with benign or malignant thyroid disease...

Accurate measurement of intraocular pressure (IOP) is essential in paediatric glaucoma management. Children require serial measurements and examination under anaesthesia (EUA). Most anaesthetic agents reduce IOP, and the ideal time to measure IOP under anaesthesia is questionable. STUDY PURPOSE: To determine the effect of sevoflurane induction, followed by intravenous ketamine infusion on IOP, in children undergoing EUA for glaucoma or suspected glaucoma, and to establish the earliest time point at which reliable, repeatable IOP measurements can be obtained under anaesthesia...
