Abstract Background Delirium is an important postoperative complication. Recent research suggested that 5-hydroxytryptamine 3 (5-HT3) receptor antagonists may have clinical effect in the treatment and prevention of delirium. We investigated the association between 5-HT3 receptor antagonists and the occurrence of postoperative delirium (POD). Methods Retrospectively, the electronic medical records were reviewed in patients aged ≥ 65 years who underwent orthopedic lower limb surgery under regional anesthesia (spinal or combined spinal-epidural anesthesia) and administered intravenous 0.075 mg palonosetron or 0.3 mg ramosetron prior to the end of surgery between July 2012 and September 2015. POD incidence and anesthesia-, surgery-, and patient-related factors were evaluated. To investigate the association between 5-HT3 receptor antagonists and the occurrence of POD, multivariable logistic regression analysis was performed. Results Of the 855 patients included, 710 (83%) were administered 5-HT3 receptor antagonists. POD was confirmed in 46 (5.4%) patients. 5-HT3 receptor antagonists reduced the POD incidence by 63% (odds ratio [OR] 0.37; 95% confidence interval [CI], 0.15–0.94; P = 0.04). Moreover, the POD incidence decreased by 72% (OR 0.28, 95% CI 0.10–0.77, P = 0.01) when palonosetron was administered. Other identified risk factors for POD were emergency surgery, older age, hip surgery, lower body mass index, and intraoperative propofol sedation. Conclusion 5-HT3 receptor antagonists may be related with a significantly reduced risk for POD in older patients undergoing orthopedic lower limb surgery. Notably, palonosetron was more effective for POD prevention.

Propofol and dexmedetomidine are the two most popular intravenous sedatives during anesthesia. However, data comparing the effects of these two sedatives during spinal anesthesia on postoperative recovery are still insufficient. We retrospectively analyzed the medical records of patients aged ≥65 years who underwent orthopedic surgery under spinal anesthesia between March 2012 and February 2017. The patients were allocated into two groups according to the intraoperative sedatives: the propofol group and dexmedetomidine group. We analyzed the incidence of postoperative delirium, analgesic requirement, and rescue anti-emetic treatment. A total of 1045 patients were included in the analysis. After propensity score matching with the propofol group, the dexmedetomidine group showed a lower incidence of postoperative delirium (odds ratio, 0.19; 95% CI, 0.07–0.56; p = 0.011). Postoperative analgesic and anti-emetic requirement were not significantly different between the two groups (p = 0.156 and 0.245, respectively). Multivariate logistic regression analysis revealed that intraoperative sedation, age, preoperative albumin level, and hip surgery were significantly associated with the incidence of postoperative delirium. This study showed that intraoperative dexmedetomidine sedation under spinal anesthesia during lower limb surgery is associated with a lower incidence of postoperative delirium compared with propofol sedation.

Drug Errors

Drug errors are very common in medical field especially in anaesthesia where it’s the game of drugs. Here, we are presenting a case in which accidentally we injected lignocaine with adrenaline in place of heavy bupivacaine. Patient was of geriatric age group and posted for lower limb surgery under combined spinal epidural anaesthesia after placement of epidural catheter lumber puncture was done and 3ml of lignocaine with adrenaline was injected. After this patient develop complete sensory, motor blockade with hypotension. Level of block was up to T12 level patient was monitored for signs and symptoms of ransient neurologic syndrome (TNS) and anterior spinal artery syndrome for 24 hours. After 24 hours patient develop no complications and posted for surgery under general anaesthesia.so we have to be very careful about the labelling of drugs.

We would like to present the first report of severe acute dystonic reaction after a single administration of metoclopramide during cesarean section under combined spinal-epidural anesthesia.  During elective cesarean section, a 30-year-old female vomited four times and was treated with 10mg intravenous metoclopramide and 8mg intravenous ondansetron.  Nausea subsided with the antiemetic treatment, but two minutes later, patient had rapid eye blinking, uncontrollable head movement, and became unresponsive.  Bolus of 50mg intravenous diphenhydramine resolved the acute dystonic symptoms within seconds.  Patient was again oriented times three, with no recollection of symptoms, and remained symptom free for the rest of admission.
