Comparison of intrathecal levobupivacaine with and without fentanyl in combined spinal epidural for labor analgesia.

BACKGROUND: The initiation of epidural infusion immediately after intrathecal (IT) injection to prolong labor analgesia has gained increasing popularity. The effect of additional intrathecal fentanyl on levobupivacaine for labor analgesia has not been fully investigated. We wished to determine if addition of IT fentanyl to IT levobupivacaine in combined spinal epidural (CSE) could prolong obstetric analgesia when epidural infusion is initiated promptly. MATERIAL/METHODS: In this randomized controlled trial, 40 nulliparous parturients in labor were recruited to receive either IT 2.5 mg levobupivacaine (L) or IT 2.5 mg levobupivacaine + 25 microg fentanyl (LF). A 10 ml/h epidural infusion of 0.125% levobupivacaine and 2 microg/ml fentanyl was immediately started. The proportion of parturients who delivered without breakthrough pain and the duration of analgesia were analyzed with the x2 test and Kaplan-Meier technique (using a log-rank test), respectively. Sensory block, motor block, pain scores, and post-block side effects were also evaluated. RESULTS: The percentage of parturients with "successful" blocks, i.e. parturients not requiring further analgesic supplementation, was significantly higher in LF (87.5% vs. 44%, p<0.05). The duration of analgesia was also significantly longer in group LF (mean 530 min +/- SE65 vs. 361 +/- 66, p<0.05). CONCLUSIONS: The addition of 25 microg intrathecal fentanyl to 2.5 mg levobupivacaine as part of CSE for labor analgesia decreased the incidence of labor breakthrough pain and resulted in a longer duration of labor pain relief. This may decrease the need for supplemental labor pain relief and the anesthetists' workload in the delivery suite.

Effects of epidural analgesia using ropivacaine on the mother and the newborn during labor.

OBJECTIVE: To evaluate the effects of epidural analgesia using 0.2% Ropivacaine on the mother, newborn and during labor. METHODS: This study was conducted at the Zeynep Kamil Obstetric, Gynecology, and Pediatric Research and Training Hospital in Istanbul, Turkey, between July 2003 and April 2004. Eighty pregnant women of 37-41 weeks' gestation were enrolled in the study. Forty cases received epidural analgesia (group 1) and the control group composed 40 cases (group 2). Duration of labor, systolic and diastolic blood pressures at initial, 15th, 30th, 45th and 60th minutes, and number of breathing per minute, pulse rates, fetal heart rates and presence of motor block were recorded. Blood gas assessments from the umbilical cord, 1st and 5th minute Apgar scores were noted following the delivery. Way of delivery, adverse effects and complications of the epidural analgesia were recorded. RESULTS: Mean age of the cases was 24.79 +/- 4.72 years. Duration between full cervical dilation and delivery (phase 2) was significantly longer in group 1 (p<0.01). Sixty minutes systolic arterial pressure was significantly lower in group 1 (p<0.05). In group 1, diastolic arterial pressures at 15th, 45th, 60th minutes (p<0.01) and 30th minute (p<0.05) were significantly lower when compared to the initial values. No significant differences were recorded in terms of breathing rates, umbilical cord CO2, O2, pH levels and Apgar scores between the 2 groups. The most common adverse effect of epidural analgesia was sedation (59%). The second dose of Ropivacaine was needed in 24 (61.5%) cases in group 1. In group 1, 29 (74.4%) patients expressed their pleasure as very good regarding the epidural analgesia. CONCLUSION: Epidural analgesia, if administered by a specialist to a properly selected patient at proper time, leads to a comfortable delivery by relieving the pain. It can be performed safely after taking an informed consent.

[Characteristics of cervix dilatation during labor].

Based on the results obtained from studies into the dynamics of cervical dilatation during delivery at term by echoscopic techniques, the author considers if there is a potential biomechanics what is responsible for dilatation of the mouth of the womb and based on the hydraulic cervical tissue distention caused by gauge blood pressure occurring during labour pains. The physiological nature of cervical dilatation features seen during delivery is discussed in terms of the dilatation biomechanics proposed.

Placental transfer of lead in mother/newborn pairs of Maracaibo City (Venezuela).

The placental transfer of lead (Pb) from mother to newborn in seventeen pregnant women receiving medical care at Adolfo Pons Hospital, Maracaibo (Venezuela), is presented. Maternal blood was collected by venipuncture during the first stage of labor, while neonatal blood was taken from the umbilical cord vein; placental blood samples were obtained at the time of delivery. Lead determination was carried out by graphite furnace atomic absorption spectrometry. Blood Pb levels (mean +/- SD, microgram/L) of 53.2 +/- 31.8, 46.3 +/- 24.5 and 66.3 +/- 33.3 were found for newborns, placentas and mothers, respectively. Significant blood Pb correlations were observed. Results indicated that even when the mother had a low blood lead level the placenta did not have a restrictive barrier-type effect to protect against Pb transfer from mother to newborn. Neonates' blood Pb concentrations were much lower than the accepted upper limit of 250 micrograms/L Pb.

[Puerperal deciduometritis. Importance of mechanical cervical dilatation].

A prospective, longitudinal, comparative, experimental design, was carried out at CMN T HGZ No. 16, from Dec 5, 1988 to July 5, 1989, in order to evaluate the importance of cervical dilatation in puerperal endometritis management. Two groups of thirty patients each, were formed at random. Cervical dilatation was performed in Group A, and it was not done in Group B. Signs and symptoms as uterine pain, uterine sub-involution, fever, fetid and/or purulent lochia remitted in two to three days average, and hospital stay was six days for both groups. During the study two patients of each group showed complications (6.66%). Therefore, these results show that cervical dilatation, performed as a part of puerperal deciduometritis management, has little or none therapeutic value.

Elective cesarean section in mares: eight cases (1980-1989).

From 1980 to 1989, 8 cesarean sections were performed on an elective basis in 5 mares. Four mares had partially obstructed pelvic canals; 2 of these mares had previously lost foals because of dystocia. Cervical adhesions that might obstruct passage of the fetus through the pelvic canal was suspected in the fifth mare. Cesarean section was performed prior to mares entering the first stage of labor. Readiness for birth was estimated by development of the mare's mammary gland and the presence of colostrum in the udder. A ventral midline celiotomy provided excellent exposure and healed without complications in all instances. Eight viable foals were produced. One foal developed bacterial pneumonia and septicemia after surgery and died. Follow-up evaluation of the 7 foals discharged from the hospital failed to reveal complications associated with elective cesarean section. All mares survived the procedure. Fetal membranes were retained for up to 72 hours following surgery; however, systemic complications secondary to retained placenta did not develop. Three mares were bred subsequent to elective cesarean sections, with each mare conceiving the year following surgery. Three foals were produced by 1 mare and 2 foals have been produced by another mare by elective cesarean sections.

Scalp infection after fetal monitoring in labour.

Neonatal scalp infection was reviewed over a four year period. The occurrence of such infection was found to be 0.14% of those infants monitored in labour using a spiral scalp electrode and 0.16% of those infants undergoing instrumental delivery. The duration of labour and the membrane-rupture delivery interval did not differ significantly from the total population. Scalp infection after monitoring occurred significantly later (day seven) than after instrumental delivery (day three) and was less often associated with positive bacterial cultures. Scalp damage is probably important in the aetiology of scalp infection, and the course of infection related to the degree of trauma.
