Intrathecal morphine analgesia and low-dose dopamine for oliguria in severe maternal pulmonary hypertension. A case report.

Maternal pulmonary hypertension can be life threatening, and many problems and complications can occur during labor and delivery as well as postpartum. A case of severe maternal pulmonary hypertension was monitored with a pulmonary artery catheter. Intrathecal morphine was administered for labor analgesia, and low-dose dopamine was utilized for maternal oliguria. Neither the morphine nor the dopamine resulted in adverse maternal hemodynamic effects. Both analgesia and resolution of the oliguria were accomplished.

Ultrasonographic guidance for central venous access during pregnancy.

Real-time ultrasonographic imaging of vascular and anatomic neck structures allows easy visualization of the right internal jugular vein and carotid artery. Application of this technology during pregnancy may reduce potential complications encountered with central venous monitoring and will be especially useful in cases of difficult anatomy.

Sleep spindles in the human hippocampus: normal or epileptic activity?

Spindles of 12-14 Hz were recorded in the hippocampus of 13 epileptics during sleep. This activity was more prominent in patients in whom the hippocampal region was not the site of the primary focus and in whom the electrical activity was normal during wakefulness. Spindles were more numerous during stage 2 non-rapid-eye-movement sleep, especially in patients who had seizures in this stage. It is postulated that this activity is either a normal activity of human brain or an evoked response of the hippocampus to an epileptic afferent discharge. In either case, hippocampal spindles may contribute to the triggering of nocturnal seizures.

[The pertinence of microscopic analysis of the urine as a diagnostic test for asymptomatic bacteriuria in pregnancy].

The genito-urinary tract is the most frequent site of infection during pregnancy. Asymptomatic bacteriuria is found in 2 to 12% of the obstetrical population. The importance of its detection is underlined by the fact that 20 to 40% of untreated cases will present acute pyelonephritis. Our study's first aim was determining the incidence of asymptomatic bacteriuria in our population. Our results show an incidence of 3.9%. Second, routine mandatory prenatal laboratory examinations include urinalysis and urine culture. Considering the fact that we already do a routine culture, we questioned the pertinence of the microscopic part of urinalysis for screening asymptomatic bacteriuria. Our study has shown that no amount of erythrocytes, leucocytes, bacteria, pus or combination thereof has sufficient sensitivity and/or specificity to be used for screening. We thus conclude that in our context of budget restrictions, the microscopic analysis of urine should be abandoned as a routine test. The biochemical part of urinalysis could be done easily with dipsticks at a lower cost. Urine culture remains the gold standard for detection of asymptomatic bacteriuria.
