Regional intraarticular delivery of local anaesthetics is effective in treating postoperative pain following total knee or hip replacement. Recent research efforts have been only partially successful in achieving sustained release of the analgesic agent, in part due to limited understanding of the biological environment into which these formulations are administered. This study aimed to detail the composition and properties of postoperative periarticular fluid (PO-PAF). PO-PAF was collected from 8 patients and the composition and physicochemical properties determined...

The direct anti-proliferative and pro-apoptotic effects of local anesthetics have been well documented in various cancers. However, whether local anesthetics affect cancer metastasis and their underlying molecular mechanisms are not well understood. In this work, we show that ropivacaine at the clinically relevant concentration significantly inhibits esophageal cancer cell migration. Interestingly, ropivacaine at the same concentration does not display inhibitory effects on esophageal cancer cell growth and survival...

If the use of natural opiates, such as opium, is more than millennial, the history of synthetic opioids begins after 1950, with the development of the so-called 'modern' anaesthetic techniques. In 1962, in Belgium, the use of fentanyl, the first synthetic opioid for use in anaesthesia, is described. Subsequently, the use of opioids at high doses during surgery became common. However, over the last twenty years, many studies have questioned this practice, highlighting the many unknowns as the side effects of these molecules...

Heterotopic heart transplants were introduced in 1974. The technique allows the patient's native heart to be preserved in situ, alongside the transplanted heterotopic donor heart (Newcomb et al., 2004). We present the case of a nulliparous woman who underwent heterotopic heart transplant in infancy, and subsequent explantation of the donor heart eleven years later, when her native heart function recovered. In adulthood the patient attended pre-pregnancy counselling and was awaiting cardiac magnetic resonance imaging when she presented pregnant at 6 weeks-of-gestation...

The aim of the study was to find out what perioperative risk factors predicted complications in patients having reconstructions with radial forearm free flaps (RFFF). We organised a retrospective study of 169 patients (mean (range) age 54 (22-86) years, 100 of whom were female) who had oral and maxillofacial tumours resected, and reconstructed with RFFF, from January 2011-December 2016. We recorded predictive variables, subdivided into: personal and clinical (sex, age, weight, coexisting conditions, history of smoking, radiotherapy, and primary lesions); haemodynamic (perioperative concentrations of haemoglobin and albumin, blood loss, blood transfusion, urinary output (ml), and rate (ml/kg/hour), and infusion rates for crystalloids and colloids (ml/kg/hour, and volumes given intraoperatively and postoperatively for 24hours); and anaesthetic and surgical (American Society of Anesthesiologists(ASA) grade, visual analogue pain score (VAS), and duration of tourniquet and operation)...

The anaesthesiological management of patients scheduled for cardiac surgery has been refined distinctively over the last decade due to different reasons. The continuing growth of the elderly patient population and the increasing number of combined cardiac surgery procedures in octogenarians on the one hand are one aspect. The rapid development of minimally invasive cardiac surgery and the enhancements in mechanical, artificial heart assist devices on the other hand can be seen as additional decisive factors...

BACKGROUND: Percutaneous Achilles tenotomy (PAT) is performed during the final phase of casting with Ponseti method. Several settings have been proposed as venues for this procedure, however it is increasingly being performed in theatre under a general anaesthetic (GA). General anaesthesia, however, is expensive and not without risks. The purpose of the present study was to compare results of outpatient releases to theatre releases, and assess current practising trends among orthopaedic surgeons...

BACKGROUND: Childbirth may cause the most severe pain some women experience in their lifetime. Epidural analgesia is an effective form of pain relief during labour and is considered to be the reference standard. Traditionally epidural analgesia has been delivered as a continuous infusion via a catheter in the epidural space, with or without the ability for the patient to supplement the analgesia received by activating a programmable pump to deliver additional top-up doses, known as patient-controlled epidural analgesia (PCEA)...

Spinal anaesthesia with local anaesthetics has limited duration. Different additives have been used to prolong spinal anaesthesia. The aim of this study was to determine the efficacy of adding dexamethasone to bupivacaine in spinal anaesthesia specially whether it would prolong the duration of sensory block/ surgical analgesia and post-operative analgesia/pain free period or not. This randomized, prospective, double-blind, clinical study was conducted in the Department of Anaesthesia, Analgesia and Critical Care of Combined Military Hospital, Chittagong from October 2016 to August 2017...

Eclampsia is a common problem in pregnancy in Bangladesh. It is a severe form of preeclampsia which affects 5 to 7% of pregnancies is a significant cause of maternal & neonatal morbidity & mortality. Pre-eclampsia when complicated with generalized tonic-clonic convulsions and/or coma is called eclampsia. The term eclampsia is derived from a Greek word, meaning "like a flash of lightening". It may occur quite abruptly, without any warning manifestations. Eclampsia is a major cause of maternal mortality & morbidity as well as foetal loss worldwide, particularly in the third world...

We evaluated the utility of noninvasive stroke volume variation (SVV) as a functional haemodynamic predictor for fluid responsiveness under different ventilation modes [assist control (A/C), synchronized intermittent mandatory ventilation (SIMV), and continuous positive airway pressure (CPAP)] in 45 anaesthetized dogs, using an electrical velocimetry device. Receiver operating curve analysis confirmed the best predictive value during SVVA /C (12.5% of cut-off value; 75% sensitivity and 86% specificity) followed by SVVSIMV (13...

INTRODUCTION: Achilles tendinopathy (AT) is a cause of pain and disability affecting both athletes and sedentary individuals. More than 150 000 people in the UK every year suffer from AT.While there is much preclinical work on the use of stem cells in tendon pathology, there is a scarcity of clinical data looking at the use of mesenchymal stem cells to treat tendon disease and there does not appear to be any studies of the use of autologous cultured mesenchymal stem cells (MSCs) for AT...

The majority of surgeons leave internal stents following laparoscopic pyeloplasty, which necessitates a second anaesthetic for removal. A novel technique of placing external nephro-ureteric stents, thus obviating a second procedure for retrieval, is shown in this video bank. As demonstrated in the video, a Kirschner wire (K-wire) is used to thread the stent in place. Although, there are few reports of using externalised stents in laparoscopic pyeloplasty, it is believed that this technique has not been previously described...

BACKGROUND AND OBJECTIVES: Infiltration of surgical wound with local anaesthetics attenuate postoperative pain. However, side effects can also occur. Somatostatin (SST) and its analogues like octreotide reportedly reduce peripheral sensitisation. The current study evaluates peripherally mediated antinociceptive effect of SST in a rat model of postoperative pain. This was compared with bupivacaine and morphine under identical experimental conditions. DESIGN: Randomised vehicle-controlled blind study...

BACKGROUND: Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) may complicate a patient's postoperative recovery in several ways. Monitoring of processed electroencephalogram (EEG) or evoked potential (EP) indices may prevent or minimize POD and POCD, probably through optimization of anaesthetic doses. OBJECTIVES: To assess whether the use of processed EEG or auditory evoked potential (AEP) indices (bispectral index (BIS), narcotrend index, cerebral state index, state entropy and response entropy, patient state index, index of consciousness, A-line autoregressive index, and auditory evoked potentials (AEP index)) as guides to anaesthetic delivery can reduce the risk of POD and POCD in non-cardiac surgical or non-neurosurgical adult patients undergoing general anaesthesia compared with standard practice where only clinical signs are used...

INTRODUCTION: The emergence of hyaluronic acid dermal fillers with lidocaine has transformed the minimally invasive treatment of wrinkles, lines and folds of the face. Patients can be treated quickly, painlessly and without the need for large doses of lidocaine. Therefore, it is important to scientifically evaluate the merits of lidocaine-containing products over those without. METHODS: The two products, with (UJU) and without lidocaine (UJ), were randomly injected into nasolabial folds of 75 healthy volunteers with varying skin types in a split face study, age ranging 26-60 years...

BACKGROUND: While opioids are the mainstay for post-operative analgesia after lower segment caesarean section, they are associated with various untoward effects. Ultrasound guided transversus abdominis plane (TAP) block has been postulated to provide effective analgesia for caesarean section. We evaluated the analgesic efficacy of this block for post caesarean analgesia in a randomised controlled trial. METHODS: One hundred thirty-nine mothers undergoing caesarean delivery were randomised to receive TAP block with either 20 ml 0...
