Paramedian Spinal Anaesthesia, Real Time Ultrasound Guiding

Keywords

paramedian spinal anesthesia, real time, ultrasound, knee surgeries, conventional

Brief summary

To identify the value of using the ultrasound in applying a commonly used regional anaesthetic procedure (spinal anaesthesia) when compared with the conventional landmark guided approach, regarding the efficiency of the anaesthetic technique, incidence of associated common complications and patient's satisfaction.

Design outcomes

Primary

Measure	Time frame
Number of puncture attempts	during the time taken for introducing the regional anesthetic technique in the intraoperative period

Secondary

Measure	Time frame
The visibility of the ligamentum flavum-dura mater complex by the US.	during the time taken for introducing the regional anesthetic technique in the intraoperative period
Duration of the anaesthetic procedure	during the time taken for introducing the regional anesthetic technique in the intraoperative period
The incidence of paraesthesia and backache	during the time taken for introducing the regional anesthetic technique in the intraoperative period
Landmark palpation easiness score	during the time taken for introducing the regional anesthetic technique in the intraoperative period
Patient's satisfaction score regarding the anaesthetic technique	within 2 hours in the postoperative period
Post dural puncture headache (incidence-onset-duration-severity)	within 3 days after the operation
The incidence of failure of introducing spinal anaesthesia using each of the study techniques.	during the time taken for introducing the regional anesthetic technique in the intraoperative period
