The safety and efficacy of parent-/nurse-controlled analgesia in patients less than six years of age.

UNLABELLED: Over the past 5 yr, we have treated nonsurgical and postoperative pain in children <6 yr of age by using a patient-controlled analgesia pump to deliver small-dose continuous IV opioid infusions supplemented by parent- and nurse-controlled opioid bolus dosing. We call this technique parent-/nurse-controlled analgesia (PNCA). Because the safety and efficacy of PNCA have not been previously evaluated, we have undertaken a prospective, 1-yr observational study to determine patient demographics, effectiveness of analgesia, and the incidence of complications (pruritus, vomiting, and respiratory depression) in patients receiving PNCA. Data were collected on 212 children (98 female) who were treated on 240 occasions with PNCA for episodes of pain. Patients averaged 2.3 +/- 1.7 yr of age and 11 +/- 5 kg, and received a median of 4 (range 2-54) days of PNCA therapy. Maximum daily pain scores were < or =3/10 (objective pain scale) or < or =2/5 (objective or self-report pain scale) in more than 80% of all occasions of PNCA use. PNCA usage was associated with an 8% incidence of pruritus and a 15% incidence of vomiting on the first day of treatment. Nine children studied received naloxone, four (1.7%) for treatment of PNCA-related apnea or desaturation. All had improvement in their symptoms after naloxone administration. IMPLICATIONS: Parent-/nurse-controlled analgesia provided effective pain relief in most children <6 yr of age experiencing nonsurgical or postoperative pain. The observed incidence of vomiting and pruritus was similar to that seen in older patients treated with patient-controlled analgesia. However, significant respiratory depression, although uncommon, did occur, thus reinforcing the need for close patient monitoring.

Videotape increases parental knowledge about pediatric pain management.

UNLABELLED: Pediatric pain management often depends on parents recognition and assessment of their child's pain and their beliefs as to whether the pain should be treated. Parental misconceptions concerning pain assessment and pain management may therefore result in inadequate pain treatment, particularly in patients who are too young or too developmentally handicapped to self-report their pain. We hypothesized that viewing a concise, educational videotape would provide parents with instructive information that could correct misconceptions concerning pain and pain management in children. To do this, we evaluated the impact of an educational videotape on parental responses to a questionnaire about pediatric pain management. Parents of children scheduled for inpatient, postoperative hospital care were studied. After answering 30 questions, parents were randomly assigned to either view (Group 1) or not view (Group 2) a 19-min educational videotape. Immediately after viewing the videotape (Group 1), or 30 min after taking the first test (Group 2), parents were asked to answer the same questionnaire a second time. The effect of seeing the videotape was assessed by comparing post-pre test score differences using paired t-test. One-hundred parents were studied. Randomization was effective in assigning equitable groups. Initial scores of percent answers correct in each group were not different ([mean +/- SD] Group 1 [n = 50]: 68.7% +/- 18.8% vs Group 2 [n = 50]: 61.5% +/- 22.7%; P = 0.09). Viewing the videotape effectively increased test scores: paired t-test within groups demonstrated a significant difference in Group 1 (22.4% +/- 16.5%, P < 0.0001), whereas Group 2 scores changed to a much lesser degree (2.7% +/- 8.3%, P = 0.0271). All parents who viewed the videotape stated that it was informative regarding their understanding of their child's pain management. This study demonstrates the effectiveness of an educational videotape in changing parental knowledge concerning postoperative pediatric pain. This effective and efficient teaching medium may be useful in improving pain management in postoperative pediatric surgical patients. IMPLICATIONS: Pediatric pain management often depends on parents recognition and assessment of their child's pain and their beliefs as to whether the pain should be treated. This prospective, randomized, controlled study demonstrated the effectiveness of an educational videotape in changing parental knowledge concerning postoperative pediatric pain. This effective and efficient teaching medium may be useful in preventing inadequate pain management in postoperative pediatric surgical patients.

Bacterial colonization and infection rate of continuous epidural catheters in children.

UNLABELLED: Continuous epidural infusions are widely used for postoperative analgesia in children. We prospectively studied the incidence of bacterial colonization of caudal and lumbar epidural catheters, as well as the incidence of serious systemic and local infection, in 210 children after short-term epidural analgesia. Using aseptic technique, epidural catheters were inserted into either the lumbar or the caudal epidural space based on the preferences of the anesthesia team and/or clinical indication. The integrity of the catheter and overlying transparent dressing site was evaluated by a member of the pediatric pain service at least once a day. The catheters were aseptically removed if the patient had a fever greater than 39 degrees C, if the dressing was compromised, or when epidural analgesia was no longer required. The subcutaneous portion of the catheter was semiquantitatively cultured. Cellulitis (erythema, swelling, purulent discharge, pustule formation, or tenderness) was diagnosed by examination of the epidural insertion site. The mean (+/- SD) age of patients in the caudal catheter group (n = 170) was 3 +/- 3 yr; their mean weight was 13 +/- 11 kg. The mean (+/- SD) age of patients in the epidural catheter group (n = 40) was 11 +/- 4 yr; their mean weight was 36 +/- 23 kg. All catheters remained in place for 3 +/- 1 days (range 1-5 days). There was no serious systemic infection (meningitis, epidural abscess, or systemic sepsis). Of all epidural catheters, 35% (73 of 210) were colonized. Gram-positive colonization was similar in caudal (25%; 43 of 170) and lumbar (23%; 9 of 40) catheters. Gram-negative organisms were cultured from 16% of the caudal catheters (27 of 170) and 3% of the lumbar catheters (1 of 40). In patients treated with caudal epidural catheters, children aged >3 yr were less likely to have colonized epidural catheters than younger children. Age did not affect the probability of developing cellulitis at the insertion site. Although patients aged <3 yr with caudal catheters had a slightly greater risk of cellulitis than children aged >3 yr (14% vs 9%), this association was very weak (P = 0.33). We observed that, despite bacterial colonization of caudal and lumbar epidural catheters, serious systemic and local infection after short-term epidural analgesia did not occur in our study. IMPLICATIONS: Continuous epidural infusions are widely used for postoperative analgesia in children. We found no serious systemic infections after short-term (3 days) continuous epidural analgesia in children.

Epidural analgesia in the management of severe vaso-occlusive sickle cell crisis.

OBJECTIVES: To determine whether continuous epidural analgesia could effectively decrease pain and thereby improve the management of severe vaso-occlusive crisis in children with sickle cell disease who were unresponsive to conventional analgesic therapy. DESIGN: Retrospective observational study. SETTING: A tertiary care hospital with a large pediatric sickle cell patient referral population. PATIENTS: The study describes nine children in 11 painful vaso-occlusive crises, unresponsive to high-dose systemic opioids, nonsteroidal anti-inflammatory drugs, and adjunctive measures, who underwent continuous epidural analgesia to control pain. OUTCOME MEASURES: Subjective pain scores, arterial oxygen saturation monitoring, and plasma lidocaine levels. METHODS: Placement of an epidural catheter for the administration of a continuous infusion of local anesthetic, alone, or in combination with fentanyl, in the management of vaso-occlusive crisis. RESULTS: An initiation of epidural analgesic therapy, 8 of 9 patients reported severe pain (8 to 10 on a scale of 0 to 10, 0 = no pain, 10 = the worst pain they ever experienced). Analgesic was immediate (pain score 0 to 2) in 8 of 9 patients, and continuously effective in 9 of 11 crises. Five patients required either the addition of fentanyl or changing the local anesthetic from lidocaine to bupivacaine to maintain analgesia for 2 to 5 days. In 7 of 9 patients, oxygen saturation dramatically increased from 87 to 95% to 99 to 100% after epidural analgesia was initiated. In all patients, plasma lidocaine levels ranged from 1.1 to 4.6 mg/L and dose-related toxicity did not occur. One patient developed hypotension secondary to high sympathetic blockade (T-4), one had an inadvertent dural puncture during insertion of the catheter, one had the epidural catheter removed for fever, and one achieved analgesia only transiently. There were no other complications, and epidural analgesia was not associated with sedation, respiratory depression, or limitation of movement. All epidural catheters were cultured on removal, and colonization did not occur. CONCLUSIONS: Epidural analgesia with local anesthetics administered alone or in combination with fentanyl effectively and safely treats the pain of sickle cell vaso-occlusive crisis unresponsive to conventional pain management and does so without causing sedation, respiratory depression, or significant limitation on ambulation. Furthermore, early treatment of painful crisis with this technique may improve oxygenation, a critical factor in the evolution of further sickling.

End of life care for infants with AIDS: ethical and legal issues.

Complex cases involving end-of-life care for infants with AIDS raise a variety of ethical and legal concerns. Health care providers should understand the issues involving proper treatment, including adequate relief of pain at the end of life, and a context for examining the suffering of caregivers.
