Comparison of Clonidin, Pethedin and Fentanyl for Post-spinal Anesthesia Shivering in Elective Caesarian Sections

ABSTRACT: Introduction & Objective: Post operative shivering is a prevalent complication of general and spinal anesthesia. Many drugs were used for prevention and treatment of shivering. The objective of this study was the comparison of clonidin, pethedin and fentanyl for treatment of post spinal anesthesia shivering. Materials & Methods: In this double blind randomized clinical trial, we compared the effects of 3 drug regimens to treat post operative shivering after spinal anesthesia in 60 elective caesarian sections with ASA class 1. Patients were divided into 3 groups (20 patients for each group). Each group received intravenously either pethedin 25 mg, clonidine 30 μg or fentanyl 50 μg. If a patient did not respond to the first dose, the same dose would be repeated up to a total of 3 times (with 5 minute intervals). Homodynamic changes, treatment responses and side effects were recorded. Then the resulting data were analyzed by SPSS software and chi-square test. Results: Considering control of shivering after first injection with pethedin 70%, clonidin 50% and fentanyl 30% with (p=0.04) major side effects in pethedin group were tachycardia 10%, nausea & vomiting 15%. In clonidine group the main side effects were dry mouth & drowsiness (16.7% & 3.3%) respectively. Fentanyl group had only 3.3% nausea vomiting accounting for the fewest number of side effects (p< 0.05). Homodynamic was stable in fentanyl & clonidine groups. Conclusion: We concluded that, clonidine offers better thermodynamics along with modest failure rate but pethedin was most effective with more serious side effects

Effect of Oral Clonidine onPost Operative Nausea andVomiting in GynecologicalLaparoscopic Surgery

Introduction & Objective: Despite advances in anesthesia nausea and vomiting is still a frequent post operative complication of general anesthesia for laparoscopic surgery. Many treatment modalities have been tried to reduce this unpleasant side effect. In this study we assessed the efficacy of oral clonidine in laparoscopic surgery in gynecological laparoscopic surgery. Materials & Methods: In this prospective double blind study, 86 ASA classes 1 or 2 were selected. Study group (n=43) received clonidine (0.2 mg tablet with 50 cc water) 60 – 90 minutes before surgery while control group ( n=43) received placebo. The patients were monitored for presence of nausea and vomiting for 24 hours. Moreover sedation scores and hemodynamic changes between 2 groups were compared. Collected data were analyzed by SPSS using chi–square and Fisher tests. Results: Nine patients (20.9%) in study group and 19 patients (44.2%) in control group nauseated (p = 0.0 21) while 16.3% of patients in study group and 34.9% in control group vomited (p = 0.048). Conclusion: Clonidine had statistically significant effect on reducing the incidence of both nausea and vomiting. It is a simple effective solution and its routine use can be suggested in gynecological laparoscopic surgery

Comparison of Preanesthetic Sedation after Intranasal Administration of Fentanyle, Ketamin and Midazolam

Introduction & Objective: Induction of anesthesia in children can be a challenge for anesthetist. A stormy induction may increase the personality & behavioral changes. Therefore, it is desirable that they enter the operating room sedated. Many drugs are used for preanesthetic medication and there are many routes for administration. One route of administration is nasal mucous. In this study we compared the effect and side effect of three drugs (midazolam, ketamin and fentanyle) after intra nasal administration. Materials & Methods: This is a double blind clinical trial. In this study we selected 60 patients (20 patients for every group A, B or C.) We used 3 mg/kg ketamin or 3µg/kg fentanyle or 0.3 mg/kg midazolam by intranasal spray. After administration and in 5, 10 and 15 minutes, we observed the SPO2, PR and RR. After 15 min’s we separated children from parents and brought them to the operating room and controlled the acceptance of separation, depth of sedation with Ramsay score, acceptance of mask and tolerance of IV canulation. The data were then analyzed using K2 and kruskal-wallis test. Results: In our study we found that in SPO2 fentanyle had the highest rate of reduction even though none of the children had SPO2 lower than 90%. There were no differences between drugs in RR. In fentanyle group, we had the lowest rate and in ketamin group the highest rate. Midazolam had the medium rate. The rate of sedation for acceptance of separation from parents had no difference between the groups and all drugs with this dosage were effective for this aim. However, in Ramsay score, acceptance of mask and tolerance of IV canulation, the midazolam was more effective than the others. Conclusion: Intranasal administration of midazolam is a safe route for sedation in children in the pre-anesthetic time

Epidemiology and outcomes of hospital-acquired bloodstream infections in intensive care unit patients: the EUROBACT-2 international cohort study

PurposeIn the critically ill, hospital-acquired bloodstream infections (HA-BSI) are associated with significant mortality. Granular data are required for optimizing management, and developing guidelines and clinical trials.MethodsWe carried out a prospective international cohort study of adult patients (&gt;= 18 years of age) with HA-BSI treated in intensive care units (ICUs) between June 2019 and February 2021.Results2600 patients from 333 ICUs in 52 countries were included. 78% HA-BSI were ICU-acquired. Median Sequential Organ Failure Assessment (SOFA) score was 8 [IQR 5; 11] at HA-BSI diagnosis. Most frequent sources of infection included pneumonia (26.7%) and intravascular catheters (26.4%). Most frequent pathogens were Gram-negative bacteria (59.0%), predominantly Klebsiella spp. (27.9%), Acinetobacter spp. (20.3%), Escherichia coli (15.8%), and Pseudomonas spp. (14.3%). Carbapenem resistance was present in 37.8%, 84.6%, 7.4%, and 33.2%, respectively. Difficult-to-treat resistance (DTR) was present in 23.5% and pan-drug resistance in 1.5%. Antimicrobial therapy was deemed adequate within 24 h for 51.5%. Antimicrobial resistance was associated with longer delays to adequate antimicrobial therapy. Source control was needed in 52.5% but not achieved in 18.2%. Mortality was 37.1%, and only 16.1% had been discharged alive from hospital by day-28.ConclusionsHA-BSI was frequently caused by Gram-negative, carbapenem-resistant and DTR pathogens. Antimicrobial resistance led to delays in adequate antimicrobial therapy. Mortality was high, and at day-28 only a minority of the patients were discharged alive from the hospital. Prevention of antimicrobial resistance and focusing on adequate antimicrobial therapy and source control are important to optimize patient management and outcomes

The role of centre and country factors on process and outcome indicators in critically ill patients with hospital-acquired bloodstream infections

Purpose: The primary objective of this study was to evaluate the associations between centre/country-based factors and two important process and outcome indicators in patients with hospital-acquired bloodstream infections (HABSI). Methods: We used data on HABSI from the prospective EUROBACT-2 study to evaluate the associations between centre/country factors on a process or an outcome indicator: adequacy of antimicrobial therapy within the first 24&nbsp;h or 28-day mortality, respectively. Mixed logistical models with clustering by centre identified factors associated with both indicators. Results: Two thousand two hundred nine patients from two hundred one intensive care units (ICUs) were included in forty-seven countries. Overall, 51% (n = 1128) of patients received an adequate antimicrobial therapy and the 28-day mortality was 38% (n = 839). The availability of therapeutic drug monitoring (TDM) for aminoglycosides everyday [odds ratio (OR) 1.48, 95% confidence interval (CI) 1.03-2.14] or within a few hours (OR 1.79, 95% CI 1.34-2.38), surveillance cultures for multidrug-resistant organism carriage performed weekly (OR 1.45, 95% CI 1.09-1.93), and increasing Human Development Index (HDI) values were associated with adequate antimicrobial therapy. The presence of intermediate care beds (OR 0.63, 95% CI 0.47-0.84), TDM for aminoglycoside available everyday (OR 0.66, 95% CI 0.44-1.00) or within a few hours (OR 0.51, 95% CI 0.37-0.70), 24/7 consultation of clinical pharmacists (OR 0.67, 95% CI 0.47-0.95), percentage of vancomycin-resistant enterococci (VRE) between 10% and 25% in the ICU (OR 1.67, 95% CI 1.00-2.80), and decreasing HDI values were associated with 28-day mortality. Conclusion: Centre/country factors should be targeted for future interventions to improve management strategies and outcome of HABSI in ICU patients
