Continuous spinal anesthesia versus combined spinal epidural block for major orthopedic surgery: prospective...

Area of Science:

• Anesthesiology
• Orthopedic Surgery

Background:

• Continuous spinal anesthesia (CSA) and combined spinal epidural anesthesia (CSE) are established methods for major lower limb orthopedic procedures.
• Both techniques are recognized for their safety and reliability in providing anesthesia.

Purpose of the Study:

• To compare the blockading properties and side effects of CSA versus single interspace CSE.
• To evaluate outcomes in patients undergoing major hip or knee surgery.

Main Methods:

• A prospective randomized clinical study involving 240 patients undergoing hip arthroplasty, knee arthroplasty, or femoral fracture treatment.
• Patients were randomized to receive either CSA or CSE, with detailed recording of block characteristics, technical difficulties, and adverse events like paresthesia and postdural puncture headache (PDPH).

Main Results:

• A significantly lower incidence of paresthesia was noted in the CSE group.
• CSE resulted in a significantly higher sensory blockade level.
• Arterial hypotension occurred more frequently in the CSE group, while PDPH incidence was similar between groups.

Conclusions:

• Both CSA and CSE provide effective surgical conditions with a low complication rate.
• CSA was associated with a lower sensory blockade level and reduced hemodynamic changes compared to CSE.
