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.

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.

To determine whether having preoperative airway photographs will change the preanesthetic airway plan. ⋯ Our findings suggest that the addition of dynamic airway photographs to preoperative airway reports affects airway management plans among a variety of anesthesia care providers. In general, dynamic airway photographs can aid preoperative airway management planning.

Obese parturients both greatly benefit from neuraxial techniques, and may represent a technical challenge to obstetric anesthesiologists. Several studies address the topic of obesity and neuraxial analgesia in general, but few offer well described definitions or rates of "difficulty" and "failure" of labor epidural analgesia. Providing those definitions, we hypothesized that increasing body mass index (BMI) is associated with negative outcomes in both categories and increased time needed for epidural placement. ⋯ Obesity is associated with increasing technical difficulty and failure of neuraxial analgesia for labor. Practitioners should consider allotting extra time for obese parturients in order to manage potential problems.

Case Reports
Monitoring of the intraoperative analgesia by pupillometry during laparoscopic splenectomy for splenic hydatid cyst.
Echinococcosis causes a hydatid cyst, a worldwide disease. Human beings are intermediate hosts, but dogs complete the life cycle of the cestode. The most common presentation sites are the liver and lungs. ⋯ This is regulated by the autonomous sympathetic system. It appears to be more sensitive and reliable than using simple variations in heart rate and blood pressure. It is an easy and safe to use method that might allow a reduction in postoperative analgesic requirements.
