Randomized Controlled Trial Clinical Trial
Comparison of the maternal and fetal effects associated with intermittent or continuous infusion of extradural analgesia.
Eighty normal primigravidae received an extradural dose of 0.25% bupivacaine and were then allocated randomly to receive "top-ups" of 0.25% bupivacaine (group A) or an infusion of 0.125% bupivacaine (group B). Group B received supplementary top-ups if required. Group A required more top-ups (147 vs 80) (P < 0.01). ⋯ More episodes in group A were related to top-ups (42/71 vs 18/69; P < 0.01) but the incidence of episodes after a top-up was similar (group A, 42/147 (28.6%); group B, 18/80 (22.5%)). In group A, 31/42 events (73.8%) were transient compared with 11/18 persistent episodes (61.1%) (> 10 min duration) in group B. However, the difference in the deceleratory patterns did not influence the condition of the fetuses at delivery.

The management of pediatric pain is a complex, multifaceted subject. By viewing pediatric pain management as a priority, health care providers may diminish children's suffering in hospital settings. Critical care nurses can make a difference by increasing awareness of pain issues, incorporating pain assessment tools into their flow sheet, being knowledgeable about pain management interventions, and collaborating with the other health care team members to cope effectively with each child's individual pain management needs.

Randomized Controlled Trial Comparative Study Clinical TrialEpidural patient-controlled analgesia: an alternative to intravenous patient-controlled analgesia for pain relief after cesarean delivery.
Epidural administration of an opioid analgesic by means of a patient-controlled analgesia (PCA) system was compared with conventional intravenous PCA for pain relief after cesarean delivery. One hundred seventeen healthy women were randomly assigned to receive hydromorphone either intravenously (IV-PCA) or epidurally (EPI-PCA) after cesarean delivery with epidural bupivacaine for operative anesthesia. The hydromorphone requirements were 3.4 and 4.2 times more in the IV-PCA group on the first (P less than 0.01) and second (P less than 0.01) postoperative days, respectively. ⋯ Pruritus was reported more frequently in the EPI-PCA (67%) than in the IV-PCA (33%) group. Nausea was experienced by only 10% of patients in the IV-PCA and 6% in the EPI-PCA group. There was no evidence of postoperative respiratory depression, with minimal oxygen saturation values of 93% (+/- 3%) and 94% (+/- 1%) in the IV-PCA and EPI-PCA groups, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Randomized Controlled Trial Clinical Trial
Intrathecal clonidine as a sole analgesic for pain relief after cesarean section.
In a small number of studies and isolated case reports, intrathecally administered clonidine has been reported to relieve intractable cancer pain and to prolong spinal anesthesia induced by various local anesthetics. A double-blind placebo-controlled clinical trial was carried out in order to evaluate the effect of intrathecal clonidine on pain following cesarean section. Twenty patients who underwent elective cesarean section received, 45 min after general anesthesia, either 150 micrograms (n = 10) clonidine or saline (control group, n = 10) intrathecally. ⋯ Maximal reduction of systolic arterial pressure was 15 +/- 9%, of diastolic arterial pressure 22 +/- 12%, and of mean arterial pressure 18 +/- 12%. Clonidine did not affect arterial hemoglobin oxygen saturation or PaCO2. Patients in the clonidine group were significantly more sedated (P less than 0.05) and more frequently reported a dry mouth (P less than 0.01) compared to the normal saline group.(ABSTRACT TRUNCATED AT 250 WORDS)
