Successful lipid rescue of local anesthetic systemic toxicity following peribulbar block

Local anesthesia is commonly used to perform cataract surgery. We present a case in which local anesthesia systemic toxicity, which occurred after peribulbar block. It is a life-threatening complication if it is not recognized early and appropriately resuscitated can be fatal. This case report attempts to highlight the need for trained personnel, with suitable monitoring and recent guidelines in the management of local anesthesia systemic toxicity surgery under a regional technique

Anesthesia for cesarean delivery in a patient with large anterior mediastinal tumor presenting as intrathoracic airway compression

Anterior mediastinal mass is a rare pathology that presents considerable anesthetic challenges due to cardiopulmonary compromise. We present a case that was referred to us in the third trimester of pregnancy with severe breathlessness and orthopnea. An elective cesarean delivery was performed under combined spinal epidural anesthesia with a favorable outcome. We discuss the perioperative considerations in these patients with a review of the literature

Is intraoperative endoscopy safe in a child with Kasai procedure?

We report a case of venous air embolism which occurred during intraoperative endoscopy in a five-year-old boy who had undergone Kasai procedure in his infancy. The child had a cardiac arrest during the procedure from which he could not be resuscitated. The awareness about this complication would allow rapid diagnosis, which is vital to provide specific treatment and prevent fatal outcome

Ultrasound guided interscalene block is a safe technique in neck breathers

Regional anaesthesia is challenging in surgical patients with anatomical abnormalities. Patients who have undergone total laryngectomy have a permanent tracheostomy, and these individuals are termed as neck breathers. These patients have distorted anatomy due to radiation and chemotherapy. We are report the successful management of a neck breather with distorted neck anatomy for surgery of the arm with an ultrasound guided interscalene block

Effects of intravenous dexmedetomidine on hyperbaric bupivacaine spinal anesthesia: A randomized study

Background and Objectives: The present study was designed to evaluate the effect of intravenous dexmedetomidine on spinal anesthesia with 0.5% of hyperbaric bupivacaine. Materials and Methods: One hundred American Society of Anesthesiologists (ASA) physical status I/II patients undergoing elective surgeries under spinal anesthesia were randomized into two groups of 50 each. Immediately after subarachnoid block with 3 ml of 0.5% hyperbaric bupivacaine, patients in group D received a loading dose of 1 μg/kg of dexmedetomidine intravenously by infusion pump over 10 min followed by a maintenance dose of 0.5 μg/kg/h till the end of surgery, whereas patients in group C received an equivalent quantity of normal saline. Results: The time taken for regression of motor blockade to modified Bromage scale 0 was significantly prolonged in group D (220.7 ± 16.5 min) compared to group C (131 ± 10.5 min) (P < 0.001). The level of sensory block was higher in group D (T 6.88 ± 1.1) than group C (T 7.66 ± 0.8) (P < 0.001). The duration for two-dermatomal regression of sensory blockade (137.4 ± 10.9 min vs. 102.8 ± 14.8 min) and the duration of sensory block (269.8 ± 20.7 min vs. 169.2 ± 12.1 min) were significantly prolonged in group D compared to group C (P < 0.001). Intraoperative Ramsay sedation scores were higher in group D (4.4 ± 0.7) compared to group C (2 ± 0.1) (P < 0.001). Higher proportion of patients in group D had bradycardia (33% vs. 4%) (P < 0.001), as compared to group C. The 24-h mean analgesic requirement was less and the time to first request for postoperative analgesic was prolonged in group D than in group C (P < 0.001). Conclusion: Intravenous dexmedetomidine significantly prolongs the duration of sensory and motor block of bupivacaine spinal anesthesia. The incidence of bradycardia is significantly higher when intravenous dexmedetomidine is used as an adjuvant to bupivacaine spinal anesthesia. Dexmedetomidine provides excellent intraoperative sedation and postoperative analgesia
