ABSTRACT
STUDY OBJECTIVE: The primary aim was to compare postoperative pain scores in patients undergoing laparoscopic cholecystectomy and receiving intravenous (IV) or oral (PO) acetaminophen (APAP) as part of a multimodal analgesic regimen to examine whether PO APAP is non-inferior to IV APAP. DESIGN: Retrospective analysis. SETTING: Ambulatory surgical center (ASC) in an academic setting. PATIENTS: 579 patients (18-70 years old), American Society of Anesthesiologists physical status I-III, undergoing laparoscopic cholecystectomy. INTERVENTIONS: Patients received 1,000 mg IV APAP intraoperatively (n = 319) or 1,000 mg PO APAP preoperatively (n = 260). MEASUREMENTS: The primary outcome was the median difference in post-anesthesia care unit (PACU) end-pain scores between the groups. Median pain scores were also compared on PACU admission, and at 15, 30, 45, and 60 minutes. Additional measures include PACU rescue-analgesia consumption, time to first PACU rescue analgesia, intraoperative use of opioid and nonopioid analgesics, PACU length of stay, and PACU rescue nausea and vomiting therapy. MAIN RESULTS: In both groups, the PACU median end-pain score was 2. The 90% confidence interval (CI) for difference in median pain scores between groups was [0, 0]; the CI upper limit was below the non-inferior margin of 1 pain-score point, indicating PO APAP's non-inferiority to IV APAP. There were no statistically significant differences in the percentages of patients receiving PACU hydromorphone equivalents between the IV and PO groups (75% vs. 77%, P = 0.72) or in the mean dose received (0.5 mg vs. 0.5 mg, P = 0.66). CONCLUSION: Single-dose PO APAP is non-inferior to IV APAP for postoperative analgesia in ASC laparoscopic cholecystectomy patients. The value of single-dose IV APAP in this population should be further explored.
ABSTRACT
BACKGROUND: Staging in Hepatoblastoma has recently become controversial. In developing countries diagnosis occurs mostly in advanced stages under these circumstances, we propose another option that can be considered of prognostic value. METHOD: A retrospective analysis of cases diagnosed with Hepatoblastoma (HB), treated in a single Institution, in nine years was conducted. Chemotherapeutic regimens were analyzed, as well as the number of courses administered and response to treatment. RESULTS: Thirty-two patients were studied. Patients had symptoms from 1 to 25 weeks before diagnosis. SIOP stratification was used, finding 12 cases in PRETEXT II, 6 cases in PRETEXT III, and 14 cases in PRETEXT IV. No single case was identified in PRETEXT I. CONCLUSIONS: When comparing survival using the PRETEXT system, SIOP and our study showed marked differences. These results may not be comparable due to differences in tumor volume among the same PRETEXT stratification. We believe that tumor volume is related to prognosis.
