Relationship Between Central Obesity and Spread of Spinal Anesthesia in Female Patients.
Central obesity may be related to the spread of spinal anesthesia in female patients. Fifty-seven female patients undergoing spinal anesthesia were allocated to either the central obesity or noncentral obesity group. ⋯ Multiple linear regression analyses showed that maximal sensory blockade was related to central obesity (P = .004). Central obesity is related to a more extensive spread of spinal anesthesia in female patients.

In the Beginning-There Is the Introduction-and Your Study Hypothesis.
Writing a manuscript for a medical journal is very akin to writing a newspaper article-albeit a scholarly one. Like any journalist, you have a story to tell. You need to tell your story in a way that is easy to follow and makes a compelling case to the reader. ⋯ Therefore, in most clinical and basic science studies and manuscripts, the alternative hypothesis is stated, not the null hypothesis. Also, in the Introduction, the alternative hypothesis is typically stated in the direction of interest, or the expected direction. However, when assessing the association of interest, researchers typically look in both directions (ie, favoring 1 group or the other) by conducting a 2-tailed statistical test because the true direction of the effect is typically not known, and either direction would be important to report.

Comparative StudySevoflurane Posttreatment Attenuates Lung Injury Induced by Oleic Acid in Dogs.
In animal models, both sevoflurane and propofol protect against acute lung injury (ALI), especially when administered prior to ALI onset. We hypothesized that when compared to propofol, sevoflurane administration after the onset of acute respiratory distress syndrome would mitigate oleic acid (OA)-induced ALI in dogs. ⋯ When compared with propofol, sevoflurane attenuates OA-induced lung damage. However, despite this effect on lung histology and inflammation, sevoflurane worsened oxygenation in OA-induced ALI, possibly via inhibition of hypoxic pulmonary vasoconstriction.

Topical Ropivacaine in Prevention of Post-Tonsillectomy Pain in Adults.
Post-tonsillectomy pain is 1 of the most intense postoperative pain conditions. However, optimal and sufficient postoperative analgesic treatment remains unclear. We investigated the effect of topical ropivacaine for post-tonsillectomy pain in 160 adult outpatient surgery patients over 2 postoperative weeks. ⋯ Topical ropivacaine failed to reduce pain intensity during the first postoperative week. We observed no major adverse effects.
