Randomized Controlled Trial
Anesthesia management with ultrasound-guided thoracic paravertebral block for donor nephrectomy: A prospective randomized study.
To determine the efficacy of ultrasound-guided thoracic paravertebral block intraoperatively and 24 hours postoperatively in patients undergoing donor nephrectomy. ⋯ Continuous thoracic paravertebral block provides good intraoperative stability with a low anesthetic requirement and reduces postoperative morphine consumption for up to 24 hours. Ultrasound guided technique enhanced the safety of TPVB and provides analgesia without major complications.

Randomized Controlled Trial Comparative Study
Preprocedural ultrasound assessment does not improve trainee performance of spinal anesthesia for obstetrical patients: a randomized controlled trial.
This randomized controlled trial was designed to evaluate the efficacy of additional information from preprocedure ultrasound examination to aid anesthesiology trainees performing spinal anesthesia for obstetric patients. ⋯ In this study of junior anesthesia trainees performing obstetrical spinal anesthesia with preprocedure ultrasound and landmark technique or landmark technique only, no significant difference was observed in the number of attempts, duration of spinal placement, subjective ease of spinal placement, or any other measured secondary outcome.

Randomized Controlled Trial
Effect of stellate ganglion block on hemodynamics and stress responses during CO2-pneumoperitoneum in elderly patients.
Elderly patients undergoing elective laparoscopic cholecystectomy (LC) were given right stellate ganglion block (RSGB) to observe its effects on the hemodynamics and stress response during carbon dioxide (CO2)-pneumoperitoneum. ⋯ Right stellate ganglion block can reduce blood catecholamines during CO2-pneumoperitoneum to maintain perioperative hemodynamic stability and prevent adverse cardiovascular events in elderly patients.

Observational Study
Hypocapnia measured by end-tidal carbon dioxide tension during anesthesia is associated with increased 30-day mortality rate.
To evaluate the relationship between intraoperative end-tidal carbon dioxide (etco2) values and clinical outcomes with special attention on 30-day postoperative mortality and secondarily on hospital length of stay (LOS). ⋯ Low etco2 level during anesthesia is associated with an increase in postoperative mortality rate and LOS. These results emphasize the importance of preventing hypocapnia during anesthesia to improve surgical outcomes.

Comparative Study
The effect of second-stage pushing and body mass index on postdural puncture headache.
To explore how pushing during labor and body mass index affect the development of postdural puncture headache in parturients who experienced dural puncture with Tuohy needles. ⋯ Parturients who did not push before delivery and parturients with body mass index ≥50kg/m(2) were less likely to develop postdural puncture headache in a univariate analysis. Similar trends were demonstrated in a multivariate model, but were no longer statistically significant.
