A comparison of patient-controlled analgesia with oxycodone and morphine after total abdominal hysterectomy surgery

We compared the analgesic profile between patient-controlled analgesia (PCA) using oxycodone and morphine in post total abdominal hysterectomy patients. Eighty-four ASA I or II patients, aged 18 to 65 years who underwent total abdominal hysterectomy were recruited into this prospective, double blind, randomised controlled study. They were randomised to receive either PCA oxycodone 0.7 mg per bolus or PCA morphine 1 mg per bolus for postoperative pain relief. At the end of surgery, all patients received IV morphine 0.1 mg/kg and skin incision was infiltrated with 20 mls of bupivacaine 0.25%. Post-operative pain scores, opioids consumptions, sedation scores and side effects were assessed upon arrival and at 30 minutes after arrival to recovery area, as well as at 6 hours and 24 hours after the operation in the ward. Patients’ overall satisfaction was also assessed 24 hours postoperatively.No significant differences were observed in terms of postoperative pain scores, opioids consumption, sedation scores, side effects as well as patient’s overall satisfaction between the PCA oxycodone and PCA morphine group. Oxycodone was comparable to morphine as PCA in terms of total opioid consumption, pain scores and satisfaction level for patients undergoing total abdominal hysterectomy and therefore may be an alternative to morphine in postoperative pain management as PCA

Geoeconomic variations in epidemiology, ventilation management, and outcomes in invasively ventilated intensive care unit patients without acute respiratory distress syndrome: a pooled analysis of four observational studies

Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference -1·69 [-9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5-8] vs 6 [5-8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52-23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75-0·86]; p<0·0001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status
