Evaluation of the adequacy of general anesthesia in cesarean section by auditory evoked potential index: an observational study.
One of the hazards of general anesthesia for cesarean section (C/S) is the risk of intraoperative awareness with or without recall of the event. We examined the relationship between auditory evoked potential index (AAI), end-tidal isoflurane concentration and hemodynamic parameters to evaluate the adequacy of our routine general anesthetic technique in C/S. ⋯ Our current general anesthetic technique appears to provide an inadequate depth of anesthesia, especially before uterine closure as a milestone. Also, we found a moderate correlation between AAI and end-tidal isoflurane concentration and, to a lesser extent, with heart rate and mean blood pressure during isoflurane-N2O anesthesia for C/S.

Case ReportsIntrapleural misplacement of a thoracic epidural catheter in an anesthetized patient.
Thoracic epidural analgesia provides adequate postoperative pain relief and favorable outcomes in major operations. However, a small number of devastating complications have been reported. Here we present a case of asymptomatic but potentially life-threatening intrapleural insertion of a thoracic epidural catheter intended for postoperative analgesia. ⋯ After right thoracotomy, the epidural catheter was found in the right pleural cavity and was instantly removed. The patient underwent the operation smoothly and was discharged 10 days later without any sequelae. We recommend practitioners estimate the depth from the skin to the epidural space by computed tomography scan before operation and perform the placement of thoracic epidural catheter while the patient is awake to avoid accidental intrapleural misplacement.

Factors associated with vomiting in orthopedic patients receiving patient-controlled epidural analgesia.
Although patient-controlled epidural analgesia (PCEA) can effectively relieve postoperative pain in orthopedic patients, some adverse effects are still troublesome. We conducted this study to survey the possible risk factors related to vomiting induced by PCEA. ⋯ Our study demonstrated the risk factor associated with vomiting for orthopedic patients receiving PCEA was female sex. Other demographic variables and factors related to surgery or anesthesia did not have an influence on vomiting.

Randomized Controlled Trial Comparative StudyHemodynamic responses to tracheal intubation with the Glidescope videolaryngoscope: a comparison of oral and nasal routes.
Although there have been numerous favorable reports on the uses of the GlideScope videolaryngoscope (GSVL) in oral and nasal intubations, no study has compared the hemodynamic responses to oral and nasal intubations with the GSVL in a single clinical trial. The purpose of this randomized clinical study was to determine whether there was a clinically relevant difference between the hemodynamic responses to oral and nasal intubations with the GSVL. ⋯ In anesthetized adult patients, oral and nasal intubations with the GSVL can result in a similar pressor response. However, the tachycardic response to nasal intubation using a GSVL is smaller and of shorter duration than that to oral intubation using a GSVL.
