Background. Effective intrapartum analgesia attenuates pain, stress, and anxiety which cause release of stress hormones as well as beta-endorphins.Aim. The purpose of this study was to determine the effect of adding dexmedetomidine to hyperbaric bupivacaine for neuraxial analgesia for labor.Methods. Ninety laboring multiparous women were allocated to have single shot intrathecal bupivacaine alone (B), bupivacaine with fentanyl (BF), or bupivacaine with dexmedetomidine (BD). Sensory and motor block characteristics; time from injection to two dermatome sensory regression, sensory regression to S1 dermatome, and motor block regression to Bromage 1 were recorded. Labor pain was assessed with a 10 cm verbal pain scale.Results. Peak sensory block levels in the three groups were essentially the same (). The time for sensory and motor blocks to reach T10 dermatome and Bromage 1, respectively, was faster in group BD than in the other groups (). The time for sensory regression to S1 was significantly prolonged in the group BD (). Motor block regression time to Bromage 1 was also prolonged in the group BD (). Neonatal outcome was normal in all groups.Conclusion. Single shot intrathecal bupivacaine/dexmedetomidine significantly prolonged sensory block in laboring women.

Background:Hydrometrocolpos (HMC) is a clinical condition in which there is a cystic distension of the vagina (hydrocolpos), uterus and sometimes, fallopian tubes (hydrosalpinx) with fluid. This study described our experience with cases of HMC seen in our practice, and highlighted the flare in our practice.Patients and Methods:A retrospective study of cases of HMC managed at the University of Port Harcourt Teaching Hospital between September 2010 and August 2012.Results:There were seven cases; their ages ranged from 2 to 27 days (median 13 days). All the patients had abdominal distension but abdominal mass was obvious only in four. Other features varied depending on the presence of sepsis or other associated anomalies. The diagnosis of HMC was missed in all cases by the referring clinicians. One patient was referred with the diagnosis of tracheoesophageal fistula and esophageal atresia, 2 with bladder outlet obstruction, 1 with intestinal obstruction, 2 with anorectal malformation, and 1 with neonatal sepsis. Ultrasound identified bulky uterus in two cases and upper urinary tract dilatation in 3 patients. Six patients had laparotomy, 1 had hymenotomy only. Postoperative complications were basically wound sepsis and rectovaginal fistula resulted.Conclusion:Diagnosis of HMC should be considered as a differential in newborn girls presenting with lower abdominal mass. Attention to clinical detail is necessary to avoid a misdiagnosis.
