Abstract Background Epidural anesthesia is one of the preferred modes of regional anesthesia for lower limb orthopedic surgeries. This technique provides not only peri-operative anesthesia but also post-operative analgesia. Bupivacaine is commonly used local anesthetic in epidural anesthesia, many adjuvants added to local anesthetics to enhance the quality and duration of surgical anesthesia, among them are opioids, alpha 2 agonists. Opioids like fentanyl have been a popular choice, it offers faster onset and prolongs the duration of analgesia. Recently, alpha 2 agonists like clonidine and dexmedetomidine have been also used in prolonging the duration of epidural analgesia. Aim of the Work To compare the efficacy of using fentanyl and dexmedetomidine with bupivacaine in epidural block for knee surgeries, the time of onset of sensory, motor blockade and the duration of this blockade. Patients and Methods After obtaining approval from the Research Ethical Committee of Ain Shams University, this study was conducted in the operating theatres of Ain Shams University Hospital. It was a prospective double-blind randomized clinical study. Study period was 6 months. Results A total of 50 patients out of 71 consecutive patients met the inclusion criteria and consented for study. These 50 patients were randomized into two groups of 25 each. Out of the total patients, 33 were male and 17 were female. Conclusion Dexmedetomidine as an adjuvant to epidural bupivacaine is a better alternative to fentanyl as it shows faster onset of sensory and motor block, lesser time to attain maximum sensory level and prolonged duration of anesthesia.

A prospective survey of two hundred patients who received an epidural block in labour was performed in order to determine the incidence and severity of shivering, and the influence of likely associated factors. Twenty-two of the patients who shivered took part in a double-blind trial to see if epidural pethidine 25 mg, versus saline, had any effect upon shivering. Fifty per cent of patients shivered soon after the initial dose of bupivacaine. Shivering was more common among patients who had experienced shivering before epidural block, and in those who had received nitrous oxide (P<0.005). Prior intramuscular injection of pethidine did not significantly affect the incidence of shivering, and it was not influenced by the concentration of epidural bupivacaine used (0.5 or 0.25%). Shiverers were more likely to feel cold than non- shiverers (P<0.001) but shivering was generally regarded by patients as a trivial symptom, only 13 % describing it as very irritating. Shivering was abolished or considerably diminished within ten minutes in all patients who received epidural pethidine 25 mg, whereas there was no change in eight out of eleven patients who received epidural saline. These results are significant (P<0.01), and demonstrate that shivering following epidural blockade can be effectively treated with small epidural doses of pethidine.

Abstract Purpose: The previous reports tried to reduce shivering and improve neuraxial anesthesia characteristics by the systemic use of different drugs. This study was directed to evaluate the effect of pregabalin premedication on both shivering and epidural characteristics following single shot loading. Patients and Methods: Eighty female patients, ASA grade I and II, scheduled for gynecological surgeries under epidural anesthesia were studied. The patients were divided into two groups: Pregabalin (P) group and Control (C) group in which the patients received 150 mg of pregabalin and placebo capsules respectively sixty minutes prior to surgery. Following epidural loading, the onset and degree of shivering were compared between the two groups. Also, the epidural onset, level and duration were compared. The perioperative hemodynamics, sedation scores, meperidine consumption and side effects were followed up and registered. Results: The onset of shivering was significantly prolonged and the degree of shivering was less in pregabalin group compared to Control group. The duration of epidural shot was shorter in the control group in relation to the pregabalin treated patients. Regarding both onset and level of block, no significant changes were detected. The patients were more sedated with less meperidine consumption in the pregabalin group. The two groups were similar as regards the perioperative hemodynamics and occurrence of side effect. Conclusion: The premedication with pregabalin reduced onset and degree of shivering and prolonged the duration of single shot epidural block.

Abstract Context: Thyroid hormone regulates several cardiovascular functions, and low T3 levels are frequently associated with cardiovascular diseases. Whether T3 exerts any acute and direct effect on endothelial function in humans is unknown. Objective: Our objective was to clarify whether acute changes in serum T3 concentration affect endothelial function. Design, Setting, and Subjects: Ten healthy subjects (age, 24 ± 1 yr) participated in a double-blind, placebo-controlled trial at a university hospital. Interventions: T3 (or placebo) was infused for 7 h into the brachial artery to raise local T3 to levels observed in moderate hyperthyroidism. Vascular reactivity was tested by intraarterial infusion of vasoactive agents. Main Outcome Measures: We assessed changes in forearm blood flow (FBF) measured by plethysmography. Results: FBF response to the endothelium-dependent vasodilator acetylcholine was enhanced by T3 (P = 0.002 for the interaction between T3 and acetylcholine). The slopes of the dose-response curves were 0.41 ± 0.06 and 0.23 ± 0.04 ml/dl·min/μg in the T3 and placebo study, respectively (P = 0.03). T3 infusion had no effect on the FBF response to sodium nitroprusside. T3 potentiated the vasoconstrictor response to norepinephrine (P = 0.006 for the interaction). Also, the slopes of the dose-response curves were affected by T3 (1.95 ± 0.77 and 3.83 ± 0.35 ml/dl·min/mg in the placebo and T3 study, respectively; P &lt; 0.05). The increase in basal FBF induced by T3 was inhibited by NG-monomethyl-l-arginine. Conclusions: T3 exerts direct and acute effects on the resistance vessels by enhancing endothelial function and norepinephrine-induced vasoconstriction. The data may help clarify the vascular impact of the low T3 syndrome and point to potential therapeutic strategies.

Background.Whole-body washing with antiseptic solution has been widely used as part of eradication treatment for colonization with methicillin-resistantStaphylococcus aureus(MRSA), but evidence for the effectiveness of this measure is limited.Objective.To study the efficacy of whole-body washing with chlorhexidine for the control of MRSA.Design.Randomized, placebo-controlled, double-blinded clinical trial.Setting.University Hospital of Heidelberg and surrounding nursing homes.Patients.MRSA carriers who were not treated concurrently with antibiotics effective against MRSA were eligible for the study.Intervention.Five days of whole-body washing with either 4% chlorhexidine solution (treatment group) or with a placebo solution. All patients received mupirocin nasal ointment and chlorhexidine mouth rinse. The outcome was evaluated 3, 4, 5, 9, and 30 days after treatment with swab samples taken from several body sites.Results.Of 114 patients enrolled in the study (56 in the treatment group and 58 in the placebo group), 11 did not finish treatment (8 from the treatment group and 3 from the placebo group [P= .02]). At baseline, the groups did not differ with regard to age, sex, underlying condition, site of MRSA colonization, or history of MRSA eradication treatment. Eleven patients were MRSA-free 30 days after treatment (4 from the treatment group and 7 from the placebo group [P= .47]). Only groin-area colonization was significantly better eradicated by the use of chlorhexidine. The best predictor for total eradication was a low number of body sites positive for MRSA. Adverse effects were significantly more frequent in the treatment group than in the placebo group (any symptom, 71% vs 33%) but were reversible in most cases.Conclusion.Whole-body washing can reduce skin colonization, but it appears necessary to extend eradication measures to the gastrointestinal tract, wounds, and/or other colonized body sites if complete eradication is the goal.Trial Registration.ClinicalTrials.gov identifier: NCT00266448.

In Reply.— We appreciate the comments by Dr Battisti et al. As noted in the inclusion criteria for our study,1 all intubated babies with birth weights less than 1,751 g were eligible for the study. One of the advantages of a randomized double-blind study is that babies with other risk factors, including presence of a fluctuating cerebral blood flow pattern on Doppler ultrasound testing, should have equal chances of being in the treated and placebo groups.

Background Dengue hemorrhagic fever (DHF) infection causeshepatocelullar impairment. In management of DHF, World HealthOrganization (WHO) recommends the crystalloids Ringer’s acetate(RA) or Ringer’s lactate (RL), which are similar in composition toplasma. Acetate in RA is not metabolized in the liver, hence notburdening the liver, whereas lactate in RL is metabolized mostly inthe liver, thus placing a burden on the liver.Objective To compare aminotransferase changes as markers ofhepatocellular impairment subsequent to the use of RA and RL inthe management of DHF with and without shock.Methods This study was a double-blind randomized controlledtrial on DHF patients aged 1-18 years in Cipto MangunkusumoHospital who had not received prior treatment with crystalloids orcolloids. Subjects were randomly assigned to receive either RA orRL intravenously. Aminotransferase levels were examined on thefirst, second and third weeks from the onset of fever.Results Ninety-two patients who fulfilled inclusion criteria wereenrolled in this study, consisting of those without and with shock.Mean transaminase levels of patients without shock in the RA andRL groups did not differ significantly. Mean transaminase levels ofpatients with shock in the RA group were lower than those in theRL group, but this difference was not significant statistically. Meanalteration of transaminase levels in patients with and without shockwere not significantly different.Conclusion In DHF without shock, there is no significant differ-ence between aminotransferase level changes of patients receiv-ing RA and RL solutions. In DHF with shock, aminotransferaselevels of patients receiving RA tend to be lower than those receiv-ing RL, but this difference is insignificant

Since publication of the National Lung Cancer Screening Trial (NLST) results early lung cancer detection has been widely studied, targeting individuals based on smoking history and age. However, over recent decades several changes in lung cancer epidemiology, including risk factors, have taken place. The aim of the current study was to explore smoking prevalence among lung cancer patients who had been treated surgically or undergone a diagnostic operation and whether these patients would have met the NLST inclusion criteria.All patients operated on for lung cancer in a university hospital in Estonia between 2009 and 2015 were included. Data were collected from hospital records.426 patients were operated on for lung cancer, with smoking history properly documented in 327 patients (87 females; median age 67 years). 170 (52%) patients were smokers, 97 (30%) patients were ex-smokers and 60 (18%) patients were nonsmokers. The proportion of females among smokers was 15%, among ex-smokers was 9% and among nonsmokers was 87%. 107 of our patients would not have met the NLST age criteria and 128 of our patients would not have met the NLST smoking criteria. In total, 183 patients (56% (79% of females and 48% of males)) would not have met the NLST inclusion criteria.Only half of surgically treated lung cancer patients were current smokers and more than half did not meet the NLST inclusion criteria.

IntroductionRecent studies show that antibiotic therapy is safe and feasible for CT-confirmed uncomplicated acute appendicitis. Spontaneous resolution of acute appendicitis has already been observed over a hundred years ago. In CT-confirmed uncomplicated acute diverticulitis (left-sided appendicitis), studies have shown no benefit from antibiotics compared with symptomatic treatment, but this shift from antibiotics to symptomatic treatment has not yet been widely implemented in clinical practice. Recently, symptomatic treatment of uncomplicated acute appendicitis has been demonstrated in a Korean open-label study. However, a double-blinded placebo-controlled study to illustrate the role of antibiotics and spontaneous resolution of uncomplicated acute appendicitis is still lacking.Methods and analysisThe APPAC III (APPendicitis ACuta III) trial is a multicentre, double-blind, placebo-controlled, superiority randomised study comparing antibiotic therapy with placebo in the treatment CT scan-confirmed uncomplicated acute appendicitis aiming to evaluate the role of antibiotics in the resolution of uncomplicated acute appendicitis. Adult patients (18–60 years) with CT scan-confirmed uncomplicated acute appendicitis (the absence of appendicolith, abscess, perforation and tumour) will be enrolled in five Finnish university hospitals.Primary endpoint is success of the randomised treatment, defined as resolution of acute appendicitis resulting in discharge from the hospital without surgical intervention within 10 days after initiating randomised treatment (treatment efficacy). Secondary endpoints include postintervention complications, recurrent symptoms after treatment up to 1 year, late recurrence of acute appendicitis after 1 year, duration of hospital stay, sick leave, treatment costs and quality of life. A decrease of 15 percentage points in success rate is considered clinically important difference. The superiority of antibiotic treatment compared with placebo will be analysed using Fisher’s one-sided test and CI will be calculated for proportion difference.Ethics and disseminationThis protocol has been approved by the Ethics Committee of Turku University Hospital and the Finnish Medicines Agency (FIMEA). The findings will be disseminated in peer-reviewed academic journals.Trial registration numberNCT03234296; Pre-results.

Background and Aim : Background the present study was planned to evaluate the effect of 0.5% ropivacaine with adjuvants 0.15mg clonidine or 8 mg dexamethasone with consideration to the onset and duration of sensory-motor blockade, hemodynamic variables, postoperative analgesia and adverse effects. Material and Methods The study was conducted in the department of Anaesthesiology, Darbhanga medical college and hospital from April 2018 to December 2019. 105 consenting patients were included scheduled for moderate duration of upper limb surgeries of orthopedics and general surgery. Results : 124 patients were assessed for eligibility. Eleven patients did not give consent for participation and eight was not included due to not meeting inclusion criteria. 105 patients were enrolled and randomized to any of the three groups; 35 each in the intervention and the comparator groups. Finally, 35 patients in placebo and dexamethasone group each and 35 patients in clonidine group were analyzed, the rest being excluded due to failed block. Conclusion : we conclude that dexamethasone as an adjuvant is a good choice to prolong the duration of postoperative analgesia without any serious adverse effect. However, prolonged motor block is a matter of concern and the search for an adjuvant that selectively prolongs analgesia without impairing motor function continues.
