“…In recent years, ultrasound has been presented as an innovative and promising device to facilitate neuroaxial anesthesia application and it is stated that significant information can be obtained pertaining to spinal anatomy through the use of ultrasound. 6 Ultrasound is proposed to be used in preoperative evaluations particularly in patients expected to demonstrate technical difficulties in neuroaxial blocks. 7 …”

Background and Objective:The aim was to compare visibility of the spinal space in sitting and lateral positions, number of attempts, spinal needle depth, skin-dura mater distance and the possible complications; in application of spinal anesthesia, using ultrasound in pregnant patients scheduled to receive elective cesarean operations.Methods:The study was conducted prospective-randomly after receiving approval from the ethics committee and the patients’ permission. ASA I-II 50 pregnant patients were divided into two groups. The patients in Group SP were those placed in a sitting position and the patients in Group LP were those placed in a lateral position. In both groups, the skin-dura mater distance was recorded through an out-of plane technique accompanied by ultrasound. The depth of the spinal needle was measured. The number of attempts, the level of attempts recorded. The degree of visibility of the vertebral space was observed through ultrasound and was numerically scored. Intraoperative and postoperative complications were recorded.Results: There was no difference between the number of attempts, Modified Bromage Scale and mean measurements of skin-dura mater distance observed through ultrasound. The mean needle depths of Group LP were statistically found significantly higher than Group SP (p=0.002).Conclusion:Our study supports the notion that access to the skin-dura mater distance is longer in the lateral decubitus position when skin-dura mater distance is evaluated by measuring needle depth.

“…Lower requirements of ephedrine or atropine avoid pro-delirium drugs 30 and this can be extended to the very low request of intraoperative sedatives or opiates. In this sense we propose to classify SSA in relation to the bupivacaine dose use as high dose (>7.5 mg), low dose (5.1---7.4 mg), and very low dose (''minidose'', <5 mg) SSA; notwithstanding this could be relativized depending on the volume of the CSF of a concrete patient 31,32 and is perhaps modified by additives. 33--- 35 Asehnoune et al 36 observed that MAP was more stable in 50 young ambulatory surgery patients after very low SSA bupivacaine doses (4 mg plus 20 g fentanyl) vs. low (7.5 mg) bupivacaine dose, as defined by authors.…”
