A descriptive feasibility study to evaluate scheduled oral analgesic dosing at home for the management of postoperative pain in preschool children following tonsillectomy.

OBJECTIVES: The purpose of this study, in a sample of preschool children (ages 3-5 years; N = 47), was to evaluate the feasibility of scheduled analgesic dosing following outpatient tonsillectomy in order to optimize pain management. METHODS: Parents were instructed to give their child acetaminophen with hydrocodone (167 mg/5 mL) every 4 hours around the clock for the first 3 days following surgery. Parents recorded ratings of their child's pain with/without swallowing using the Faces, Legs, Activity, Cry, and Consolability (FLACC) behavioral pain scale, pain relief ratings, and severity of analgesic side effects in a home diary. Audiotaped interviews were conducted with parents to document descriptions of their experiences in managing their child's pain at home. RESULTS: Mean FLACC scores with/without swallowing were less than two at each measurement time and pain relief scores increased over time. Total analgesic dose decreased, and the number of missed doses increased over the first 3 days after surgery. Moderate-to-severe daytime sedation, nausea, vomiting, and constipation were reported by parents. DISCUSSION: Study results suggest that acetaminophen with hydrocodone is effective in relieving preschool children's pain following tonsillectomy and that parental adherence to a scheduled analgesic regimen decreases over time. Time-contingent dosing was associated with moderate to severe side effects and should be addressed in discharge teaching with parents. Findings provide insight into parents' perspective of pain management at home following tonsillectomy and methods for relieving their child's pain.

A randomized clinical trial of the efficacy of scheduled dosing of acetaminophen and hydrocodone for the management of postoperative pain in children after tonsillectomy.

OBJECTIVES: To determine the effectiveness of around-the-clock (ATC) analgesic administration, with or without nurse coaching, compared with standard care with as needed (PRN) dosing in children undergoing outpatient tonsillectomy. METHODS: Children 6 to 15 years of age were randomized to receive acetaminophen and hydrocodone (167 mg/2.5 mg/5 mL) for 3 days after surgery: Group A (N=39)-every 4 hours PRN, with standard postoperative instructions; Group B (N=34)-every 4 hours ATC, with standard postoperative instructions, without nurse coaching; and Group C (N=40)-every 4 hours ATC, with standard postoperative instructions, with coaching. Parents completed a medication log, and recorded the presence and severity of opioid-related adverse effects and children's reports of pain intensity using a 0 to 10 numeric rating scale. RESULTS: No differences were found in analgesic administration or pain intensity scores between the 2 ATC groups. Therefore, they were combined for comparison with the PRN group. Children in the ATC group received more analgesic than those in the PRN group (P<0.0001). Children in the PRN group had higher pain intensity scores compared to children in the ATC group, both at rest (P=0.017) and with swallowing (P=0.017). Pain intensity scores for both groups were higher in the morning compared with the evening (P<0.0001). With the exception of constipation, scheduled analgesic dosing did not increase the frequency or severity of opioid-related adverse effects. DISCUSSION: Scheduled dosing of acetaminophen and hydrocodone is more effective than PRN dosing in reducing pain intensity in children after tonsillectomy. Nurse coaching does not impact parent's adherence to ATC dosing.

Characteristics of medication errors and adverse drug events in hospitals participating in the California Pediatric Patient Safety Initiative.

PURPOSE: The characteristics of medication errors and adverse drug events (ADEs) in hospitals participating in the California Pediatric Patient Safety Initiative (CaPPSI) were studied to identify opportunities for improvement. METHODS: Data were collected to identify pharmacy intervention medication errors (PIMEs) with significant harm potential and ADEs identified by a validated pediatric trigger method (TADEs) and by voluntary incident reports (VADEs) from November 2003 through April 2004. Electronic trigger identification was used. The primary outcomes measured were PIMEs, TADEs, and VADEs and the characteristics of these medication errors and ADEs. A secondary outcome measure was the positive predictive value of the trigger tool. RESULTS: The rates of PIMEs, TADEs, and VADEs were 2.67, 22.3, and 1.7 per 1000 patient days, respectively. PIMEs and ADEs occurred mostly among patients age one year or older during days 0 and 1 of admission and involved the following medication categories: antiinfectives and antibiotics, analgesics and antipyretics, and electrolytic-, caloric-, and water balance-replacement preparations. Most PIMEs involved an incorrect dosage or the wrong drug. Primary diagnoses differed between those with PIMEs and VADEs and those with TADEs. All medication processes were in need of improvement except dispensing. The trigger tool identified more ADEs than did voluntary incident reports by a factor of 11 and had a positive predictive value of 16.8%. CONCLUSION: Baseline rates of PIMEs, TADEs, and VADEs for pediatric hospitals in California were determined through collaborative efforts of CaPPSI facilities. Identification of ADEs was more effective when a trigger tool was used than when incidents were voluntarily reported.

Children's expectations of pain, perceptions of analgesic efficacy, and experiences with nonpharmacologic pain management strategies at home following tonsillectomy.

PURPOSE: To document children's (ages 6-15 years) descriptions of their pain management at home following tonsillectomy. DESIGN AND METHODS: Audio-taped interviews of 80 children were transcribed and coded. Data for each response category were tabulated. RESULTS: Children reported they had more pain after surgery than expected, the pain medicine helped to take their pain away, taking the pain medicine was associated with a negative response by some children, and cold liquids/food by mouth provided pain relief. PRACTICE IMPLICATIONS: Findings provide insight into children's perspective of pain management at home following tonsillectomy and methods for relieving their pain.

Time-contingent dosing of an opioid analgesic after tonsillectomy does not increase moderate-to-severe side effects in children.

As part of a randomized clinical trial that compared three different analgesic dosing regimens ( Sutters et al., 2004 ), the purpose of this study, in children who underwent tonsillectomy, was to determine whether around-the-clock (ATC) dosing of acetaminophen with codeine, compared with as-needed (PRN) dosing, increased the frequency of moderate-to-severe opioid-related side effects (i.e., daytime sedation, lightheadedness, nightmares, nausea, vomiting, and constipation) in the first 3 days after surgery. Because no differences were found in pain intensity scores and in the amount of analgesic administered between the two ATC groups (i.e., with and without coaching), for these analyses, the two groups were combined ( n = 52) and compared with the PRN group ( n = 28). Each side effect was recoded into a dichotomous response (i.e., 0 = did not have symptoms or had slight symptoms; 1 = symptoms that were moderate, severe, or very severe) to provide an adequate sample size in each cell for the statistical analyses. No differences were found in the frequency of moderate-to-severe side effects between the ATC and PRN groups at any of the postoperative assessments. The number of children who reported moderate-to-severe daytime sedation decreased over time in both the PRN ( p = .02) and ATC groups ( p = .01). Children in the ATC groups reported a statistically significant decrease over time in vomiting ( p = .001) and feeling lightheaded or dizzy ( p = .003), and a significant increase in constipation ( p = .018). Except for daytime sedation, changes, over time, in the frequency of moderate-to-severe side effects were not observed in the PRN group.

A randomized clinical trial of the effectiveness of a scheduled oral analgesic dosing regimen for the management of postoperative pain in children following tonsillectomy.

The purpose of this study was to determine whether around-the-clock (i.e. ATC) dosing of acetaminophen with codeine, with or without nurse coaching, compared to standard care with as needed (i.e. PRN) dosing: reduced children's reports of pain intensity with and without swallowing; increased pain relief, and increased analgesic consumption. Eighty children, 6-15 years, undergoing tonsillectomy were randomized to one of three treatment groups to receive acetaminophen with codeine (120 mg/12 mg/5 ml) for 3 days after surgery: PRN group (N = 28)-every 4 h PRN, with standard postoperative instructions, without nurse coaching; ATC group (N = 26)-every 4 h ATC, with standard postoperative instructions, without nurse coaching; and ATC+coaching group (N = 26)-every 4 h ATC, with standard postoperative instructions and nurse coaching. In all three groups, significant decreases were found over time in pain intensity scores at rest (P < 0.001) and with swallowing (P < 0.001). However, mean pain scores at rest and with swallowing were >3/10 until the fourth evening after tonsillectomy. Children in both ATC dosing groups received significantly greater amounts of acetaminophen and codeine than children in the PRN group (P < 0.003). No significant differences were found in the amount of analgesic administered between the ATC dosing groups with and without nurse coaching. No significant differences were found in the amount of nausea and vomiting among the three groups. Scheduled dosing of acetaminophen with codeine did not provide adequate pain relief for children following tonsillectomy. Nurse coaching does not increase parent's adherence with an ATC dosing schedule.

A comparison of oral diazepam versus midazolam, administered with intravenous meperidine, as premedication to sedation for pediatric endoscopy.

OBJECTIVES: This study was performed to compare the effects of oral midazolam and oral diazepam, administered with intravenous (IV) meperidine, on pre-procedural, procedural, and post-procedural sedation and recovery in children undergoing diagnostic upper endoscopy. The costs of pre-procedure sedation were compared for the two benzodiazepines. METHODS: A randomized, double-blind study was conducted in 154 children (mean age 96.73 +/- 59.34 months, 53% male) undergoing endoscopy. Oral midazolam (0.5 mg/kg, maximum dose of 20 mg) or oral diazepam (0.3 mg/kg, maximum dose of 10 mg) was given before IV insertion, and with IV meperidine (2 mg/kg, maximum dose of 100 mg) given to all patients just before upper endoscopy. Further "rescue" midazolam doses (to a maximum cumulative dose of 5 mg) were given as needed to achieve a pre-procedure sedation score of > or =2. All patients received intravenous propofol for procedural sedation. Patients were evaluated for the efficacy and safety of pre-procedural sedation, sedation during upper endoscopy, and recovery following completion of the procedure. RESULTS: There were no significant differences between study groups for level of pre-procedural sedation, need for midazolam rescue in endoscopy, effectiveness of procedural sedation, occurrence of adverse events, and recovery parameters. CONCLUSIONS: Oral midazolam and diazepam, in conjunction with IV administration of meperidine, provide comparable, effective, and safe premedication for children undergoing upper endoscopy. The cost of midazolam was substantially higher than diazepam.
