Purpose: Continuous Spinal Anesthesia (CSA) is the technique of initiating and maintaining spinal anesthesia with small incremental doses of local anaesthetic injected intermittently into the subarachnoid space through a catheter. Hemodynamic instability due to high block largely limits the use of conventional Single Shot Spinal Anesthesia (SSSA) in high risk patients. Our primary aim was to observe hemodynamic changes, total fluid and vasopressor consumption and incidence of Post Dural Puncture Headache (PDPH), meningitis, focal sensory block after CSA and SSSA in young adults.Methods: Total 44 patients of ASA grades I-III aged 18-60 years, scheduled for lower abdominal and hip surgery received either CSA using 19G paediatric epidural Touhy needle and 22 G catheter (Group CSA; n=22) or SSSA with 25G Quinkes spinal needle (Group SSSA, n=22) using 0.75 % isobaric ropivacaine. Hemodynamics, total fluids &vasopressor consumption and incidence of adverse events were recorded.Results: Demographically, patients were comparable between the groups. HR and DBP was found comparable within the groups and between the groups (p>0.05). Fall in SBP was significant in SSSA group from 10-45 min with respect to baseline and from 5-25 min when compared to CSA group after induction. Mean fluid infused higher in group SSSA (p=0.0176). Five patients in SSSA group while none in CSA group had significant hypotension (p=0.190). PDPH, meningitis, focal sensory block were not observed in any of the patients.Conclusion: CSA provides better hemodynamic stability with minimal incidence of adverse events when compared to SSSA in young patients undergoing lower abdominal and hip surgeries using 0.75% Ropivacaine.

in younger population because multiple vital structures are vulnerable to injuries in the small, confined, and unprotected area. It may involve various structures in neck including soft tissues, cartilages, bones, larynx, trachea, oesophagus, pharynx, major blood vessels and important nerves. Penetrating neck trauma may present with an acute or worsening respiratory distress, airway compromise by blood or secretions, surgical emphysema, tracheal deviation secondary to hematoma, acute blood loss when associated with injury to major blood vessels like jugular and carotid, aspiration, hypoxemia and a decreasing level of consciousness [1]. These injuries may be of varying etiology like suicidal, homicidal, accidental, warfare & of varying patterns like blunt, lacerating, incised and penetrating. Mechanism of injury is very important to understand the extent of damage which in turn helps in better management of shock, hypoxemia or aspiration.
