Background: Spinal anesthesia is a safe anesthetic mode for transurethral prostate resection (TUPR). There are several studies assessing the effect of bupivacaine, lonely or accompanied by other drugs, on short duration operations. However, there is controversy regarding the exact combination.

Objectives: The aim of the study was to compare the effects of spinal anesthesia with bupivacaine and low dose lidocaine with bupivacaine alone on postoperative pain in those undergoing transurethral resection of prostate (TURP).

Materials And Methods: This was a randomized clinical trial performed in Shiraz university of medical sciences during one year. Eighty men scheduled for TURP were randomly assigned to receive spinal anesthesia with 1.5 mL bupivacaine 0.6% and 0.6 mL Lidocaine 1% or spinal anesthesia with 1.5 mL bupivacaine 0.5% in combination with 0.6 mL normal saline. The primary endpoint was the time lag between induction of spinal anesthesia and reaching the highest spinal block level. We also recorded the duration of spinal block declining to L1 level, operation duration and the admission duration.

Results: Both study groups were comparable regarding the baseline characteristics. We did not find any difference between the two study groups regarding the duration of anesthetic block reaching the maximum level (P = 0.433) and duration of decreasing it to L1 (P = 0.189). The course of postoperative recovery and duration of hospital admission were also comparable between the groups (P = 0.661).

Conclusions: Lidocaine does not have additive effects on duration and quality of spinal anesthesia with bupivacaine in those undergoing TURP.

Objective: Aminophylline, which is clinically used as a bronchodilator, antagonizes the action of adenosine, so it can be used to shorten the recovery time after general anesthesia. Therefore, we wanted to test the hypothesis that the administration of aminophylline leads to an increase in bispectral index (BIS) and clinical recovery in patients anesthetized with total intravenous anesthesia (TIVA). Methods : Ninety two patients who were scheduled for elective inguinal herniorrhaphy were enrolled in this study. All patients were premedicated with midazolam and morphine. Anesthesia was induced with propofol 2.5 mg /kg and remifentanil 2.5 µg/kg without muscle relaxant. For maintenance of anesthesia we used propofol 100µg/kg/min, remifentanil 0.2µg/kg/min and 100% oxygen with stable BIS readings in the range 40-60. After skin closure, aminophylline 4mg/ kg was given to Group A and an equivalent volume of normal saline to Group P. BIS values, heart rate, blood pressure, oxygen saturation and End tidal CO2(ETco2) were determined. Time to eye opening, extubation time and response to command were measured. Results : There were no significant differences in SpO2, ETco2 and anesthesia time. Heart rate and systolic blood pressure were found to be statistically higher (p<0.001) in Group A. Time to eye opening, hand grip and extubation were significantly shorter (p<0.001) in Group A. Bispectral index scores were significantly higher in group A.

Conclusions: Injection of aminophylline at emergence time led to significant increase in BIS and shortening recovery time from anesthesia.

Music can effectively reduce pain perception in women rather than men.

Pak J Med Sci 2013 Jan;29(1):128-31

Objective: Nowadays music is used to decrease pain and increase relaxation in clinical settings. It is hypothesized that music can affect women more easily than men. We assessed the effect of two types of music (Iranian folkloric and preferred music) on pain tolerance and pain rating in cold pressor test.

Methodology: A consecutive sample of 50 healthy Iranian medical students was enrolled. They reported pain tolerance and pain rating in cold pressor test in three different musical conditions served as the outcome measures. The results were analyzed with repeated measurement analysis of variance.

Result: Mean tolerance time was significantly higher in preferred music compared to Iranian folkloric music (F (1,48) =25.44, p=0.0001) and no music (F(1,48)=3.51, p=0.0001) conditions. There was a significant interaction when tolerance time in no music condition was compared to preferred music condition, regarding sex; Tolerance time increased more in females (F(1,48)=5.53, p=0.023). The results also indicated that pain ratings, regardless of sex, were different in three musical conditions (F(1.7,81.34)=15.37, p=0.0001).

Conclusion: Music distracted attention from pain and Women can be impressed and distracted more easily by music.
