Govt.MedicalCollege,Ananthapur
The aim of the anaesthesia management in patient with severe left ventricular dysfunction (ejection fraction 25%) is to maintain good Intraoperative hemodynamic stability; postoperative analgesia, prevent recurrence of ischemic attacks, which is achieved with combined low dose segmental epidural and ilioinguinal block.
METHODS :An old woman was admitted with history of pain and swelling in the left groin, vomitings, distension of abdomen since 5 days. History of cardiac illness present since 5 years and is on Digoxin 0.25 m.g.O.D.5days a week,Tab.Enalapril 5 m.g.O.D, ,Tab Atenolol 25 m.g. Bid, Tab clopidogrel 75 m.g.O.D..Patient stopped taking clopidogrel after starting of present complaint. Prothrombin time&.INR.were 15seconds 1.1 respectively. Midazolam 1 m.g.given i.v.as premedicant...C.V.P was used as a guide for administration of intravenous fluids. Patient in sitting posture low dose segmental epidural anaesthesia achieved by injection 5 m.l. of 2%xylocaine into L3-L4 epidural space, catheter passed &,secured. Effect adequate after 10 minutes as evident by decrease in inguinal swelling &blood pressure, facilitating ilioinguinal block, which is achieved by 40 m.l. of 0.25% Ropivacaine.Postoperatively 0.25 %Ropivacaine given epidurally for 48 hours.
RESULTS :There was fall of blood pressure from 154/86 to 84/54 after 18 minutes of combined epidural and ilioinguinal block which was managed by phenylephrine postoperatively patient had absolute pain free period for 48 hours
CONCLUSIONS :Combined low dose segmental epidural& ilioinguinal block is safe anaesthesia technique in patients with severe left ventricular dysfunction scheduled for obstructed inguinal hernia.
