Uterine rupture during extradural blockade

Unilateral Extradural Blockade In

Sir,—The hypothesis advanced by Narang and Linter [1] concerning the cause of unilateral extradural blockade is intriguing. However, I must take exception to their mathematics. Using the data from their table I, I have calculated the percentage of unsatisfactory blocks at each S—EDS (skin— extradural space distance) (table I). Spearmans rank correlation remains the same, but the authors' statem...

Uterine-vesicular rupture during trial of labor.

Uterine Rupture

Occult or incomplete rupture refers to a surgical scar separating but the visceral peritoneum staying intact. It is usually asymptomatic and does not require emergency surgery. Complete rupture can be: Traumatic: A motor vehicle accident. Incorrect use of oxytocic agent. A poorly conducted attempt at operative vaginal delivery (typically breech extraction with an incompletely dilated cervix). (...

Fentanyl and bupivacaine mixtures for extradural blockade.

In a prospective double-blind study, single dose lumbar extradural blockade was instituted in 80 healthy male patients undergoing lower abdominal surgery. Patients were assigned randomly to one of four groups. Each group received treatment with 0.5% bupivacaine 20 ml containing adrenaline 1:200 000. To this solution was added fentanyl 0, 50, 100 or 200 micrograms. The time to regression of anal...
