Eligibility

Inclusion criteria

Inclusion criteria: Patients aged 18 to 65yrs who are scheduled for elective surgeries requiring lumbar epidural anaesthesia Patients who provide written informed consent to participate

Exclusion criteria

Exclusion criteria: Refusal of consent or inability to cooperate during the procedure Pregnant and lactating women Children aged less than 18 years of age as there are many risks and complications associated with it like catheter related problems poor protein binding capacity and metabolism inadvarent dural puncture resulting accidental total spinal anaesthesia and rarely neurological issues Known contraindications of epidural anaesthesia like coagulopathy local infection uncorrected hypovolemia Any known abnormalities involving the lumbar vertebral column like severe scoliosis kyphosis previous spine surgery or neurological deficit

Design outcomes

Primary

MeasureTime frame
To measure the lumbar epidural depth in cm using ultrasonography and Loss of Resistance technique in adult patients To determine the agreement and correlation between ultrasound predicted and Loss of Resistance measured epidural depth statisticallyTimepoint: Only one reading is measured at Baseline—

Secondary

MeasureTime frame
To analyse the relationship between age gender height & BMI with the measured skin to epidural distance To quantify the strength of these associations using statistical analysisTimepoint: Only one reading is measured at Baseline that shall be used for analysis—
