Randomized Controlled Trial
A randomized controlled trial evaluating the impact of selective axillary nerve block after arthroscopic subacromial decompression.
The sensory innervation of the shoulder is complex and there are variations in the branching patterns of the sensory fibres. Articular branches from the axillary nerve to the subacromial bursa are described in more than 50% of investigated shoulders but the isolated contribution of sensory input from the axillary nerve has never been investigated clinically. We hypothesized that a selective block of the axillary nerve would reduce morphine consumption and pain after arthroscopic subacromial decompression. ⋯ Selective block of the axillary nerve has some pain relieving effect, but in this setting the effect was unpredictable, variable and far from sufficient in a large proportion of the patients.

Randomized Controlled Trial Comparative Study
A randomized double-blind comparison of the double-space technique versus the single-space technique in combined spinal-epidural anesthesia for cesarean section.
Combined spinal-epidural anesthesia (CSEA) can be performed with either a single-space technique or a double-space technique for cesarean section. We performed a double-blind randomized controlled study to compare the effect of the double-space technique with that of the single-space technique on sensory block level and side effects. ⋯ We conclude that there were no differences in intraoperative variables between the double-space technique and the single-space technique for CSEA. However, double-space CSEA for cesarean section may be beneficial for controlling postoperative pain and improving parturient satisfaction.

Randomized Controlled Trial Comparative Study
Prospective randomized comparison of cerebrospinal fluid aspiration and conventional popping methods using 27-gauge spinal needles in patients undergoing spinal anaesthesia.
Performing spinal anaesthesia using the conventional popping method with a 27-gauge (27G) spinal needle is technically difficult. In this study, we compared the aspiration and conventional popping method for spinal anaesthesia using 27G Quincke-type needles. ⋯ The aspiration method using a 27G Quincke-type needle offers clinical benefits for dural puncture compared with the conventional popping method for spinal anaesthesia.

Randomized Controlled Trial
Effect of postoperative Trendelenburg position on shoulder pain after gynecological laparoscopic procedures: a randomized clinical trial.
Laparoscopic surgery has become a standard of care for many gynecological surgeries due to its lower morbidity, pain and cost compared to open techniques. Unfortunately, the use of carbon dioxide (CO2) to insufflate the abdomen is the main contributor to post-operative shoulder pain. ⋯ In conclusion, Trendelenburg position is an easy non-pharmacologic intervention that is beneficial in reducing postoperative shoulder pain following gynecologic laparoscopic surgery.

Randomized Controlled Trial Multicenter Study
The effect of brief pre-anesthetic exercise therapy of jaw and neck joints on mouth opening, neck extension, and intubation conditions during induction of general anesthesia: a randomized controlled trial.
The effort to improve tracheal intubation process is clinically valuable. We hypothesized that a preoperative brief exercise therapy would increase mouth opening and neck extension, enhancing intubation conditions during general anesthesia. ⋯ The brief pre-anesthetic exercise improved intubation conditions and enabled faster tracheal intubation with less injury to oropharyngeal soft tissue.
