We propose a multi-pinhole fluorescent x-ray computed tomography (mp-FXCT) technique for preclinical molecular imaging that can provide the complete data necessary to produce 3-D tomographic images during anaesthesia. In this method, multiple projections are simultaneously acquired through a multi-pinhole collimator with a 2-D detector and full-field volumetric beam to accelerate the data acquisition process and enhance the signal-to-noise ratios of the projections. We constructed a 15-pinhole mp-FXCT imaging system at beamline ARNE-7A at KEK and performed preliminary experiments to investigate its imaging properties using physical phantoms and a non-radioactive I imaging agent...

OBJECTIVE: A local anaesthetic with fast onset, short and reliable duration of anaesthesia may be preferable for day care urological surgeries. Low dose lignocaine is believed to act faster and to have a shorter duration of action than low dose bupivacaine. Use of lignocaine for spinal anesthesia is discouraged now a days because of rare reports of transient neurological symptoms. The purpose of this study was to compare effectiveness and safety of low dose of lignocaine + butorphanol against low dose of bupivacaine for day care urological surgeries...

BACKGROUND: Pain is considered as being one cause of post-operative emergence agitation (EA) from sevoflurane anaesthesia. The purpose of this study was to investigate the pure effect of post-operative pain on EA after sevoflurane anaesthesia in preschool children undergoing excision of scalp nevi. METHODS: Forty-four children, 1-7 years old, undergoing scalp nevus excision were enrolled. Patients were randomly assigned to two groups: the remifentanil group received single intravenous injection of short-acting synthetic opioid, remifentanil 1 μg/kg just before the scalp incision, and the block group received scalp nerve block with 0...

Botulinum intramuscular injections are increasingly being used in the management of hypertonic musculature. Historically, injections were administered under general anaesthesia (GA), which has service and economic implications. Our delivery changed to outpatient conscious injections to improve service efficiency. A retrospective analysis of all patient injections from January 2010 to December 2015 analysed cost-benefit and efficiency of service remodelling. 472 patients were administered injections, 298 in theatre under GA and 174 without GA...

INTRODUCTION: Postoperative delirium can be a serious consequence of major surgery, associated with longer hospital stays, readmission, cognitive and functional deterioration and mortality. Delirium is an acute, reversible disorder characterised by fluctuating course, inattention, disorganised thinking and altered level of consciousness. Delirium occurring in the hours immediately following anaesthesia and delirium occurring in the postoperative period of 1-5 days have been described as distinct clinical entities...

INTRODUCTION: Single-incision laparoscopic cholecystectomy (SILC) is widely used as a treatment option for gallbladder disease. However, obesity has been considered a relative contraindication to this approach due to more advanced technical difficulties. The aim of this report was to review our experience with SILC to evaluate the impact of body mass index (BMI) on the surgical outcome. PATIENTS AND METHODS: Between May 2009 and February 2013, 237 patients underwent SILC at our institute...

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: Caesarean scar pregnancy (CSP) is a late serious complication of caesarean section. The incidence of CSP has increased worldwide in recent years. Early diagnosis and prompt therapy are crucial to avoid catastrophic complications. There are various strategies for CSP treatment, but there is no consensus on the best management for CSP. Dilation and curettage (D&C) and hysteroscopy are common and effective treatments with their advantages and disadvantages. No in-depth study of the clinical effects of hysteroscopic management of CSP after D&C treatment failure has been conducted...

BACKGROUND: A malignant hyperthermia (MH) crisis is a potentially fatal complication in anesthesia and intensive care units (ICU). Rapid administration and adequate dosage of dantrolene is the only known effective pharmacological and causal treatment of an MH crisis. International anesthesiology societies recommend an initial dose of 2.0-2.5 mg/kg body weight (BW). The necessary total dosage should be titrated up to 10 mg/kg BW depending on the effectiveness. OBJECTIVE: The goal of this study was an analysis of the stocking situation of dantrolene in Germany...

INTRODUCTION: Effective control of sympathetic response to pneumoperitoneum is vital to avoid morbidity in patients undergoing laparoscopic surgeries. This control must be achieved without any side effects of the drugs being used as well as ensuring a raid recovery from anaesthesia in order to maximise operation theatre utility. AIM: To study the effectiveness of dexmedetomidine in attenuating the haemodynamic response to pneumoperitoneum during laparoscopic cholecystectomy (using only the maintenance dose) with that of propofol and compare time to extubation, haemodynamics on extubation, sedation score after extubation and any incidence of side effects between the two study drug...

BACKGROUND: The incidence of post-discharge nausea and vomiting (PDNV) after ambulatory anaesthesia using total intravenous anaesthesia with a risk-stratified anti-emetic approach is not well documented in the literature. In this study, we outline such an approach. The goal was to achieve an acceptably low rate of PDNV both immediately and the day after surgery. METHODS: With ethics committee approval, adult patients undergoing outpatient surgery received a Propofol-based general anaesthetic plus standardised PONV-prophylaxis corresponding to their Apfel risk-score (0-4); ondansetron (risk-score 2), additional dexamethasone (risk-score 3), and additional droperidol (risk-score 4)...

BACKGROUND: Thoracic surgery requires the effective collapse of the non-ventilated lung. In the majority of cases, we accomplished, accelerated lung collapse using a double-lumen tube (DLT). We hypothesized that using the two-minute disconnection technique with a DLT would improve lung collapse during subsequent one-lung ventilation. METHODS: Fifty patients undergoing thoracoscopic surgery with physical classification I or II according to the American Society of Anesthesiologists were randomly divided into two groups for respiratory management of one-lung ventilation (OLV)...

We evaluated whether pre-emptive analgesia with a pre-operative ultrasound-guided infraclavicular brachial plexus block resulted in better postoperative analgesia than an identical block performed postoperatively. Fifty-two patients undergoing fixation of a fractured radius were included. All patients received general anaesthesia with remifentanil and propofol. Patients were randomly allocated into two groups: a pre-operative block or a postoperative block with 0.5 ml.kg(-1) ropivacaine 0.75%. After surgery, all patients received regular paracetamol plus opioids for breakthrough pain...
