Randomized Controlled TrialThe use of train of four monitoring for clinical evaluation of the axillary brachial plexus block.
The axillary approach of brachial plexus anesthesia is the most commonly used technique for forearm and hand surgery. Dynamometer is known as objective test for the clinical assessment of motor block of the nerves in brachial plexus block. However, the use of this device may not always be practical in operating room. ⋯ TOF values were gradually decreased and significant difference was observed between the development of a complete and partial motor block at 30th minute. TOF values were also significantly less in patients of complete sensory block than the patients of partial sensory block at 30th minute. The use of TOF monitoring may be beneficial to assess the objective clinical effect of motor block in the patients with axillary brachial plexus nerve block.

Randomized Controlled TrialEffect of preloading epidural space with normal saline on the incidence of complications of epidural catheter placement and spinal anesthesia for cesarean section.
To evaluate the effect of preloading the epidural space with normal saline (NS) on the incidence of complications of epidural catheter placement and spinal anesthesia for cesarean section. Two hundred and ninety parturients at full term, who were scheduled for cesarean section under combined spinal-epidural anesthesia were randomly divided into two groups: group control (I) and group NS (II). The epidural puncture was performed at the estimated L3-4 interspace with a Tuohy needle attached to a 5 ml syringe. ⋯ Blood vessel trauma in group II was significantly lower than in group I, P < 0.05. However, the incidence of paraesthesia was similar between the two groups, P > 0.05. Preloading the epidural space with NS can decrease the incidence of clinically apparent injury to blood vessels during epidural catheter placement, and can improve the effects of spinal analgesia, but does not reduce the incidence of paraesthesia.

Randomized Controlled Trial Comparative StudyE-O technique is superior to E-C technique in manikins during single person bag mask ventilation performed by novices.
Conventional E-C technique of mask holding is unreliable during single person bag mask ventilation (BMV) due mainly to leak around the mask and inexperience of the persons. In this manikin study, conventional E-C technique was compared with E-O technique during single person BMV both with experienced (n = 50) and novice (n = 50) volunteers. The E-O technique involved encircling the mask neck with the web between thumb and index finger while the other digits provided chin lift. ⋯ The conventionally taught E-C technique of single person BMV provides acceptable chest expansion on most occasions with experienced operators than novices. Novices should use E-O technique as the first choice for single person BMV. Both techniques may be used interchangeably when one fails.

Randomized Controlled TrialInexpensive video-laryngoscopy guided intubation using a personal computer: initial experience of a novel technique.
Video-laryngoscopy may provide an enhanced view of laryngeal structures compared to direct visualization. Commercial video-laryngoscopes are often expensive, limiting its adoption for routine use. We describe our initial experience using an inexpensive custom made device. ⋯ The custom-made, inexpensive, video-laryngoscopy device is safe and reliable for clinical use. Real-time visualization and endotracheal intubation were successful in all patients, including those with anticipated difficult airway. Further, this device helps in archiving the video of intubation.
