Randomized Controlled Trial Comparative StudyAxillary nerve block in comparison with intravenous midazolam/fentanyl for painless reduction of upper extremity fractures.
The painful nature of fractures has made it inevitable to use various anesthetic techniques to reduce or immobilize fractured parts. In the present study, axillary nerve block was compared with intravenous midazolam/fentanyl to induce anesthesia for Painless Reduction of Upper Extremity Fractures. The subjects in the present clinical trial consisted of 60 patients with upper extremity fractures. ⋯ In contrast, the recovery time was much shorter in the ANB group (P<0.001). No life or organ threatening complications were observed in the two groups. Axillary nerve block can be considered an appropriate substitute for intravenous sedation in painful procedures of the upper extremity.

Randomized Controlled TrialThe effects of religion and spirituality on postoperative pain, hemodynamic functioning and anxiety after cesarean section.
Spiritual elements play an important role in the recovery process from acute postoperative pain. This study was conducted to assess the effect of pray meditation on postoperative pain reduction and physiologic responds among muslim patients who underwent cesarean surgery under spinal anesthesia. This double-blinded randomized clinical trial study was conducted among muslim patients who underwent cesarean surgery under spinal anesthesia during 2011-2013 at tertiary regional and teaching hospital in Lorestan, Iran. ⋯ However, there was no significant difference in the physiological responses (systolic and diastolic blood pressure, respiration, and heart rate) any time between the groups. Religion and spirituality intervention such as pray meditation could be used as one of non-pharmacological pain management techniques for reducing pain after cesarean surgery. Also, Pray meditation provides less postoperative nausea and vomiting (PONV) and more relaxation.

Randomized Controlled TrialAdministration of higher doses of amikacin in early stages of sepsis in critically ill patients.
High-dose extended-interval dosage (HDED) regimen of aminoglycosides is now considered as the standard dosage strategy in sepsis. Although safety and efficacy of this dosing regimen is well studied, but new experiments show increased the risk of resistance development associated with %T>MIC less than 60% of the dosing interval following extended interval dosing. Moreover, limited information is available about safety of more frequent administration of high dose aminoglycosides. ⋯ This indicates a safer pattern of moderate doses with more frequent administration of amikacin at the tubular injury level. Higher doses of amikacin could be safely administered to achieve PK/PD goal of Cmax>40 and %T>MIC more than 60% of the dosing interval. This dosing regimen would be considered as an alternative to minimize the resistance development associated with the extended-interval dosing in septic patients with multi-drug resistant gram-negative organisms.

Randomized Controlled TrialProphylactic administration of fibrinogen concentrate in perioperative period of total hip arthroplasty: a randomized clinical trial study.
According to limitations in blood product resources and to prevent unnecessary transfusions and afterwards complications in perioperative period of total hip arthroplasty, authors administered fibrinogen concentrate in a pilot randomized clinical trial to evaluate bleeding and need to blood transfusion in preoperative period. Thirty patients (3-75 years old) with ASA physical status class I or II and candidate for total hip arthroplasty consequently enrolled in this study and randomly assigned into two groups: taking fibrinogen concentrate and control. Two groups were similar in serum concentration of fibrinogen, hemoglobin, and platelet preoperatively. ⋯ By adjusting time factor for two groups, we identified that the patients in fibrinogen group had lower perioperative bleeding after adjusting time factor for two groups (P=0.046). None of the patients had complications related to fibrinogen concentrate administration. The prophylactic administration of fibrinogen concentrate was safe and effective in reducing bleeding in the perioperative period of total hip arthroplasty.

Evaluation of emergency medicine residents competencies in electrocardiogram interpretation.
An electrocardiogram (ECG) leads physicians to diagnose many potentially life-threatening cardiac, metabolic, electrolyte, and toxicological conditions. This study was designed to evaluate the competency of emergency medicine residents (EMRs) in comparison with cardiologists in the interpretation of ECG when an interpretation checklist is used. This clinical trial was done in the emergency wards of the first grand general hospital of Iran. ⋯ In second-year EMRs, both ECG interpretation and ECG diagnosis scores improved significantly (P<0.05 and P<0.01, respectively). In third year EMRs, ECG interpretation was not improved but ECG diagnosis based on two methods improved significantly (P<0.05). The significant increase in accuracy of ECG interpretation and final diagnosis can be attributed to the utilization of a checklist by EMRs especially in the first year and second residents.
