His medical history included coronary artery disease and end-stage chronic kidney disease requiring haemodialysis via an arteriovenous (AV) fistula on his right arm. He was transferred to our centre with new onset heart failure and was found to have a left ventricular ejection fraction of 22% on transthoracic echo. Percutaneous coronary intervention was deemed too high risk to undertake without LVAD support. During a protracted recovery, on day 46, he required a replacement central venous catheter (CVC) and dialysis catheter. The left internal jugular vein was chosen due to the presence of existing vascular access devices elsewhere. An 8.5 Fr, 20 cm quad-lumen CVC (Multicath 4expert, Vygon, Aachen, Germany) and a 13.5 Fr, 20 cm dual lumen dialysis catheter (Hemo-cath, Nikkiso Co Ltd, Tokyo, Japan) were sited at a depth of 18 cm and 17 cm respectively, with the dialysis catheter placed proximally.</p><p>Blood gas analysis from the distal lumen of the new CVC showed a pO<sub>2</sub> of 10.8 kPa (F<sub>I</sub>O<sub>2</sub> of 0.28). A contemporaneous arterial line sample indicated an arterial pO<sub>2</sub> of 10.5 kPa. A sample from the distal lumen of the dialysis catheter indicated a more reassuring pO<sub>2</sub> of 4.24 kPa. Repeat CVC samples showed a pO<sub>2</sub> of 10 kPa from the distal lumen whilst samples taken from proximal CVC lumens indicated a pO<sub>2</sub> of 4.62 kPa, consistent with venous results. Because of these results, we were concerned that the CVC had punctured the left carotid artery. Neither line was transduced at this stage and a computed tomography (CT) angiogram was arranged urgently, which confirmed an appropriate position for both lines (Fig. 1).</p><p>This case highlights the difficulty of interpreting blood gas samples taken from a CVC in a patient with an AV fistula. The presence of a high pO<sub>2</sub> cannot be interpreted accurately because of abnormal flow of arterial blood from the fistula. However, results compatible with venous samples were taken from the proximal lumens of the CVC which complicated the interpretation of results. Although rare, cases of patients with AV fistulae in whom CVC location is unclear due to unexpected blood gas analysis data have been previously reported [<span>1, 2</span>]. It is well established that the central veins demonstrate laminar flow and that laminae vary in their oxygenation, indicating that mixing of content between the laminae does not necessarily occur [<span>3</span>]. It seems most likely in our case that the distal CVC lumen was situated sufficiently close to the fistula to allow aspiration from an arterial, well-oxygenated stream of blood.</p><p>As per Association of Anaesthetists guidance [<span>4</span>], pressure transduction","PeriodicalId":72186,"journal":{"name":"Anaesthesia reports","volume":"11 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://associationofanaesthetists-publications.onlinelibrary.wiley.com/doi/epdf/10.1002/anr3.12264","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138449403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, sugammadex can also bind to other molecules [<span>2</span>]. Here, we report a failure of sugammadex antagonism of neuromuscular block with rocuronium in a patient who was taking exogenous steroid hormones.</p><p>A 60-year-old man, scheduled for a robot-assisted nephrectomy, disclosed an ongoing use of steroids related to his bodybuilding practice. Self-medication included testosterone (750–1000 mg per week intramuscularly) and trestolone acetate (300 mg per week intramuscularly). Trestolone acetate is a selective androgen receptor modulator and a nandrolone derivative, 10 times more potent than testosterone (Fig. 1). Preoperative testing revealed a free testosterone blood level of 5540 pmol.l<sup>−1</sup> (reference value, 170–660 pmol.l<sup>−1</sup>) and total testosterone (sex hormone binding globulin, SHBG) of 134 nmol.l<sup>−1</sup> (reference value, 6.1–27.1 nmol.l<sup>−1</sup>).

After five more minutes, TOFr reached 52%. Due to this unusually slow reversal, an interaction between sugammadex and steroid hormones was suspected, and we supplemented the neuromuscular block antagonism with intravenous neostigmine 2.5 mg and glycopyrrolate 0.5 mg.

Our case suggests the potential for pharmacological interactions that may reduce the efficacy of sugammadex in antagonising aminosteroid NMBAs.

Here, we present the case of a 14-year-old girl who developed a severe post-operative acute dystonic reaction which included oculogyric crisis. We believe that ondansetron was the most likely cause, although propofol may have been a synergistic or alternative causative agent. The patient had no significant past medical history and had previously undergone two uneventful general anaesthetics which included both ondansetron and propofol. The prolonged duration and severity of the reaction and failure to fully respond to specific treatments resulted in the need for tracheal intubation and transfer to a paediatric intensive care unit. She subsequently recovered uneventfully with no ongoing neurological sequalae. Ondansetron-induced dystonic reactions are rare and unpredictable and can occur in patients who have previously received the drug without complication.
