Randomized Controlled TrialVertical infraclavicular block with local anesthetic injections at different currents.
Injecting local anesthetic at the seeking current would be appealing. It would save time and avoid potentially dangerous manipulations of the needle. This study aimed to test the hypotheses that in vertical infraclavicular block, injecting local anesthetic at a seeking current of 0.8 mA would produce the same quality of block as injecting at ≤0.5mA. ⋯ We had patients in both groups who developed complete anesthesia of the hand within 25 minutes. We conclude that the injection at 0.8 mA would result in a similar quality of block to one injected at ≤0.5 mA. The difference between two groups was not statistically significant.

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 TrialThe effect of low-dose remifentanil on the hemodynamic responses of endotracheal extubation.
Emergence from general anesthesia can be associated with coughing, agitation, and hemodynamic disturbances. Remifentanil may attenuate these responses. We have examined the effect of remifentanil on the hemodynamic response to the emergence from anesthesia and tracheal extubation. ⋯ Remifentanil attenuated the increase in both systolic and diastolic arterial pressure and heart rate after extubation compared to the control group. No differences in SpO2, cough and laryngospasm were observed between two groups. Use of a low-dose remifentanil has clinically acceptable effect in blunting the cardiovascular changes induced by tracheal extubation.

Randomized Controlled TrialThe effect of acupressure on nausea and vomiting after cesarean section under spinal anesthesia.
Postoperative nausea and vomiting (PONV) is one of the most common postoperative complications. Aside from pharmacological interventions, other complementary healing modalities have been introduced to assist patients in decreasing PONV and improving postoperative outcomes. This study examined acupressure as a safe complement to the more traditional approach of using drugs to prevent and/or relieve nausea and vomiting in the Cesarean section (C/S) under spinal anesthesia. ⋯ The amount of vomitus and the degree of discomfort were, respectively, less and lower in the study group. In view of the total absence of side-effects in acupressure, its application is worthy. Our study confirmed the effectiveness of acupressure in preventing post-operative nausea and vomiting, when applied 30 minutes prior to surgery.

Randomized Controlled Trial Comparative StudyComparison of prophylactic effects of polyurethane cylindrical or tapered cuff and polyvinyl chloride cuff endotracheal tubes on ventilator-associated pneumonia.
Because microaspiration of contaminated supraglottic secretions past the endotracheal tube cuff is considered to be central in the pathogenesis of pneumonia, improved design of tracheal tubes with new cuff material and shape have reduced the size and number of folds, which together with the addition of suction ports above the cuff to drain pooled subglottic secretions leads to reduced aspiration of oropharyngeal secretions. So we conducted a study to compare the prophylactic effects of polyurethane-cylindrical or tapered cuff and polyvinyl chloride cuff endotracheal tubes (ETT) on ventilator-associated pneumonia. This randomized clinical trial was carried out in a 12 bed surgical intensive care unit. 96 patients expected to require mechanical ventilation more than 96 hours were randomly allocated to one of three following groups: Polyvinyl chloride cuff (PCV) ETT, Polyurethane (PU) cylindrical Sealguard ETT and PU Taperguard ETT. ⋯ There was no significant difference in overinflation between three groups. The use of ETT with PU material results in reducing ventilator-associated pneumonia compared to ETT with PVC cuff. In PU tubes Taperguard has less incidence of ventilator-associated pneumonia compared to Sealguard tubes.
