The purpose of this case report is to educate fellow anesthesiologists of a complicated differential diagnosis for sudden cardiovascular collapse after spinal anesthesia. We report a case where anaphylaxis occurred while under spinal anesthesia and resulted in difficult resuscitation. A 58-year-old woman undergoing bilateral knee replacements under spinal anesthesia experienced sudden seizure and cardiovascular collapse from acute anaphylactic shock while administering a cephalosporin. ⋯ Anaphylactic shock under spinal anesthesia is an acute and life-threatening complication, worsened by the spinal-induced sympathectomy, and aggressive resuscitation is warranted. Despite the presence of overlapping symptoms of differential diagnoses, rapid identification of the cause of cardiovascular collapse is crucial given that resuscitation treatment modalities may conflict. Timing of antibiotic administration should be adjusted for spinal anesthesia cases to allow time to detect possible anaphylaxis.

Ultrasound-guided Pecs block can provide perioperative analgesia for breast surgery. A single-injection technique (COMBIPECS) combines both Pecs 1 and Pecs 2 blocks in a single needle pass. ⋯ The block was administered before the surgery after induction of general anesthesia. The patients needed minimal intraoperative analgesics and remained pain free in the postoperative period up to 24 hours after surgery.

There are limited data regarding emergent, non-operating room, intubations performed by all levels of anesthesia residents. This study was a large retrospective review of all non-operating room emergent intubations performed at a single tertiary medical center. The study evaluated the rate of difficult intubations by level of resident training, compared success rates for direct versus video laryngoscopy and evaluated the rate and success of rescue video laryngoscopy following failed direct laryngoscopy. ⋯ During emergent, non-operating room intubations, senior level residents used fewer attempts at intubations with direct laryngoscopy. Successful intubation was improved by beginning residents when video laryngoscopy was utilized. Complications were not affected by the presence of the attending anesthesiologist.

Propofol is a short-acting, intravenous sedative-hypnotic agent that is widely used for the induction and maintenance of general anesthesia and sedation. An uncommon adverse effect of propofol is green discoloration of the urine, which has been reported not only under general anesthesia but also with sedation. Although it is assumed that the phenolic derivatives of propofol can cause green discoloration of the urine, the actual origin remains unknown. The aim of this report was to identify the origin of the green discoloration of the urine using liquid chromatography-mass spectrometry (LC-MS). ⋯ We experienced a case of a patient with green discoloration of the urine after general anesthesia using propofol. Although LC-MS analysis showed 2 unique peaks in the green urine at 490 and 590 nm, obvious causes were not revealed.

Cockayne syndrome is a kind of progeria with autosomal chromosome recessiveness described first by Cockayne in 1936. Patients with this syndrome were characterized by retarded growth, cerebral atrophy, and mental retardation. We experienced an anesthetic management of a patient with Cockayne syndrome, who underwent dental treatment twice. ⋯ The values of bispectral index showed a sharp fall to 1 digit and suppression ratio more than 40, while hemodynamics was stable during induction of anesthesia with sevoflurane 8%. We should pay attention to anesthetic depth in the central nervous system in patients with Cockayne syndrome. Titration of anesthetics should be performed by the information from electroencephalography.
