An 88-year-old woman presented with acute airway obstruction caused by a large retrothyroid bleed following anterior neck trauma. Her airway was secured in the operating theatre with an awake nasal flexible optical bronchoscope tracheal intubation using an Intubating Laryngeal Mask Airway tracheal tube. Haemostasis was achieved following surgical ligation and the patient was transferred to the critical care unit. Postoperatively, a large leak around the tracheal tube was noted and a decision was made to change to an orotracheal tube with a subglottic drainage port. Our exchange technique required two experienced operators. The first operator used videolaryngoscopy with a hyperangulated blade to establish an optimal view of the larynx. The second operator placed an airway exchange catheter through the existing nasal tracheal tube to ensure airway control. The trachea was then intubated orally using a flexible optical bronchoscope observed under direct vision using the videolaryngoscope. The technique combined several simple and well-documented approaches, but importantly, the airway remained secure and visible throughout the procedure. © 2019 Association of Anaesthetists.A 33-year-old multiparous term parturient requested an epidural for labour analgesia. An accidental dural puncture was noted at the time of epidural needle insertion and an intrathecal catheter was placed. The intrathecal catheter was removed 10 h later and was noted to be intact. The following day, there was a significant leak of clear fluid from the catheter insertion site. Cerebrospinal fluid was detected using beta-trace protein testing. The patient remained asymptomatic and we deduced the cause could be a cutaneous fistula. Similar published reports have suggested the causes of similar presentations could include leakage of interstitial oedema, local anaesthetic or cerebrospinal fluid. It is important to consider the diagnosis of clear fluid leakage following an accidental dural puncture and the management of a cerebrospinal fluid-cutaneous fistula in the absence of neurological symptoms. © 2019 Association of Anaesthetists.We describe the treatment of chemotherapy-induced peripheral neuropathy in the upper limb of a patient via ultrasound-guided pulsed radiofrequency of the brachial plexus. Merestinib cost A 54-year-old female, who underwent chemotherapy and mastectomy for left-sided breast cancer, presented to the pain clinic describing continuous and severe shock-like pain in the posterolateral aspect of the left upper limb, above the elbow. A diagnosis of chemotherapy-induced peripheral neuropathy was made. Pain management with multi-modal analgesia was not fully effective and pulsed radiofrequency was offered as an alternative. Ultrasonography of the supraclavicular region was used to identify the brachial plexus, followed by pulsed radiofrequency using an insulated-tip needle that produced paraesthesia in the affected area. Onset of pain relief occurred one week post-procedure and lasted approximately 10 weeks. An estimated 80% decrease in pain intensity was reported by the patient. We propose that pulsed radiofrequency can be offered as a pain management alternative in certain presentations of chemotherapy-induced peripheral neuropathy. © 2019 Association of Anaesthetists.We describe the successful resuscitation of a 23-year-old previously healthy man who had drowned. After prolonged submersion, hypothermia, severe hypernatraemia, a prolonged time to return of spontaneous circulation was possible using a combination of extracorporal life support and early continuous veno-venous haemofiltration. This combination of clinical circumstances is rarely associated with positive outcomes, but this case demonstrates the utility of extracorporeal life support and haemofiltration in patients drowned in saltwater. © 2019 Association of Anaesthetists.This report presents an obstetric patient with no significant past medical history who underwent spinal anaesthesia for a category-three caesarean section. On examination, she had asymmetrical scapular alignment and a mild scoliosis of the lumbar spine with no functional limitation. Postoperatively the patient developed neuropathic pain symptoms in the right leg which failed to resolve with conventional analgesia. Cervical and lumbar spine magnetic resonance imaging was performed resulting in a diagnosis of a low-lying tethered spinal cord terminating at the level of L5 and congenital fusion of the C7/T1 vertebrae. A tethered spinal cord is a rare condition, which in this case had been completely asymptomatic. However, we suggest that the patient displayed musculoskeletal signs not previously widely reported, which could have indicated the presence of a potential underlying neural tube defect. Based on the imaging findings and the presence of Sprengel's deformity, the patient was diagnosed with Klippel-Feil syndrome. © 2019 Association of Anaesthetists.An 18-year-old man underwent surgery for correction of idiopathic scoliosis. Due to the requirement for intra-operative spinal cord monitoring, propofol and remifentanil total intravenous anaesthesia was chosen as the anaesthetic technique. Clonidine was given intra-operatively as part of his analgesic regimen. No long-acting opioids were administered. There was delayed emergence after switching off total intravenous anaesthesia and he remained sedated with a bispectral index of approximately 60 for 90 min. The common causes of delayed emergence were excluded. Shortly after administering naloxone, there was an increase in bispectral index and emergence from anaesthesia. We describe the successful use of naloxone to reverse the sedation effects of clonidine. © 2019 Association of Anaesthetists.The use of ultrasound in regional anaesthesia has expanded our understanding of regional anaesthesia techniques and allowed for the development of novel strategies to achieve blockade of the trunk. Several alternatives to paravertebral block have recently been proposed, but none of these new techniques have yet been shown to provide surgical anaesthesia equivalent to a paravertebral block. This case report describes the successful use of the mid-point transverse process to pleura (MTP) block as the sole anaesthetic technique for a patient undergoing breast surgery. © 2019 Association of Anaesthetists.
