Oral Oxycodone Compared With Intravenous Morphine Sulfate for Pain Management of Isolated Limb Trauma; a Randomized Clinical Trial

Introduction: Appropriate pain relief enhances patient satisfaction and reduces patient anxiety. This study aimed to compare oral oxycodone with intravenous (IV) morphine sulfate (MS) in pain management of acute limb trauma.Method: In this randomized double-blind clinical trial, patients over 14 years old, with acute isolated limb trauma were randomized to receive either 5mg IV MS or 5 mg oral oxycodone. Pain intensity and adverse effects of medications were recorded 0, 30 and 60 minutes after drug administration and compared between the groups.Result: 58 patients were studied. Pain intensity was similar between the two studied groups at 30 minutes (P = 0.834) and 60 minutes (P = 0.880) after drug administration. Furthermore, there was no significant difference between the two groups regarding decrease in pain within the defined time interval. Drowsiness was reported more frequently in MS group after 30 minutes (p = 0.006). Patients in MS group asked for more rescue analgesia. Other adverse effects were similar in both groups.Conclusion: Oral oxycodone is as effective as IV morphine sulfate in treatment of acute musculoskeletal pain following blunt limb trauma

Rare fatal poisoning through dermal exposure to paraquat

Paraquat skin contact occurs less frequently and is rarely fatal. This article reports a case of a 45-year-old man who presented with dysphagia, respiratory distress and grade two, and third skin burns focusing on the upper body after accidental exposure to paraquat. He was admitted to the hospital 6 days after the first contact. The urine sodium dithionate test was strongly positive. The O 2 saturation at admission was 52%, which reached 91% with a bag valve mask. Rising blood liver enzymes, urea, creatinine, and respiratory acidosis in the venous blood gas analysis were observed in the lab data. In the course of hospitalization, the patient was intubated due to oxygen level dropping. Evidence of acute respiratory distress syndrome and decreased level of consciousness was also observed. However, despite treatment with corticosteroids, antioxidants, and hemodialysis, he died on the fourth day of hospitalization. It is concluded that dermal exposure with paraquat could be life-threatening if the patient presented late with organ involvement

Does naloxone prevent seizure in tramadol intoxicated patients?

Background: Tramadol poisoning has increased in recent years. Seizure is one of the side-effects of tramadol toxicity. There is a controversy about possible preventive effect of naloxone in tramadol poisoning induced seizure. Therefore, this study was performed to compare seizure incidence in tramadol poisoning patients who received and did not receive naloxone, as an opioid antagonist. Methods: This study involved prospective data collection followed by retrospective analysis on 104 tramadol poisoning patients who were admitted in a referral poisoning center. The incidences of seizure were compared between patients received naloxone and those did not. Outcome was considered as survived without or with complications and death. Logistic Regression analysis was used to determine the effects of different variables on seizure incidence. Results: 70 (67.3%) of the patients were men. The mean age of the patients was 26.3 ± 9 years old. 18.3% of the patients received naloxone in their treatment period. Seizure incidence was significantly higher among tramadol poisoning patients who did not receive naloxone compare with those received naloxone (14.1% vs. 5.1%). Among different variable studied, age had a significant effect on predicting of seizure (odds ratio = 2.09; 95% of confidence interval: 1.82-2.26; P value, 0.004). Conclusions: Although the seizure incidence was lower in patients with tramadol poisoning who received naloxone, the logistic regression did not support the preventive effect of naloxone on seizure in tramadol poisoning cases

Toxico-clinical study of patients poisoned with household products; a two-year cross-sectional study

Abstract Background Several studies worldwide have investigated household product poisoning. We conducted a toxico-clinical study on the two-year prevalence of poisoning with household products. Methods This cross-sectional study was performed in Khorshid Hospital, the main referral center for poisoning cases in Isfahan, affiliated to Isfahan University of Medical Sciences, Isfahan, central Iran. All patients with intentional or unintentional household substance poisoning, referring to the poisoning emergency center of the hospital, were evaluated with respect to epidemiological and toxico-clinical features and outcomes. Results During the study period, 5946 patients were hospitalized, of which 83 (1.39%) had been poisoned with household products including 48 (57.8%) men and 35 (42.2%) women with a mean ± SD age of 34.40 ± 17.71 years. Most patients (54.2%) were in the 20–40-year-old age group. Accidental poisoning (63.9%) was the most common type of exposure (P = 0.02) predominantly in men (57.8%, P = 0.51). The most common household products were sodium hypochlorite (32.53%) followed by petroleum hydrocarbon (21.68%). Most of the accidental poisonings (77.8%) were due to petroleum hydrocarbon. 59% of cases were poisoned at home (P < 0.0001). No patient died. Conclusion Household products were not common means of poisoning in our referral center. Sodium hypochlorite and petroleum hydrocarbon were the most common substances. Most of the patients were men with accidental exposure at home. Because of the availability of the household product, the frequency and outcomes may be varied in different societies

Clinico-epidemiological evaluation of pharmaceutical/non-pharmaceutical poisoning in a referral poisoning emergency in the Central part of Iran

Abstract The pattern of poisoning varies in different societies. In this study, we investigated the clinical-epidemiological features and outcomes of poisoned patients based on the substances involved, whether pharmaceutical or non- pharmaceutical toxins. This cross-sectional study involved a retrospective chart review of all poisoned patients who presented to the poisoning emergency hospital in the center of Iran between January 2015 and December 2019. We collected data on socio-demographics, the nature of the poisoning, and the outcomes. Backward stepwise binary regression analysis was conducted to predict the mortality. Throughout the study period, 5777 patients with acute poisoning met the inclusion criteria. Of these, 3524 cases (61%) were attributed to pharmaceutical, and 2253 cases (39%) were due to non-pharmaceutical poisoning. The majority of pharmaceutical poisonings (82.9%) were intentional, whereas non-pharmaceutical poisonings accounted for 46.2% of intentional exposures (P < 0.001). Patients with non-pharmaceutical poisoning were predominantly men, older in age, and had a history of addiction compared to those with pharmaceutical poisoning (P < 0.001). In binary logistic regression analysis, patients poisoned by non-pharmaceutical substances had a significantly higher risk of mortality [Odds ratio, 3.14; (95% CI 1.39–7.10); P = 0.006] compared to those poisoned by pharmaceutical substances (P < 0.001). The pattern of poisoning differs in terms of age and gender when comparing pharmaceutical to non-pharmaceutical poisoning. Patients poisoned by non-pharmaceutical may have a worse outcome compared to those poisoned by pharmaceutical substances
