Case Report
A 68-year-old man sustained fracture of the neck of femur and was
scheduled for surgery. His previous medical records revealed that he had
dilated cardiomyopathy. He was previously admitted to the Coronary
Care Unit for episodes of congestive cardiac failure. He had no past
history of alcohol abuse or the use of
The heart rate was 74 min and regular. The systolic and diastolic
blood pressures were 96 mmHg and 60 mmHg respectively. The
respiratory rate was 16/min. There were no ronchi or rales on
auscultation. Heart sounds were normal.
Preoperative 12 lead EKG showed LBBB, rsR pattern in
v4 and poor progression of R wave in leads V1-V5. X-ray chest (Figure
2) revealed cardiomegaly. The lung fields were clear.
-adrenergic agonists.Echocardiography reports demonstrated, global hypokinesia of left
ventricle, poor systolic function, ejection fraction of 25%; mitral
regurgitation, tricuspid regurgitation and left ventricular end diastolic
dilatation.
His symptoms were well controlled with Tab Lisinopril (zestril) 2-5
mg od, Lasix 40 mg od, digoxin 0.125 mg od, and spironolactone 25 mg
od for the last 4 years, No abnormalities were noted in the laboratory
investigations. Preoperative hemoglobin level was 11.1 gm%.
A high-risk consent was obtained. Regional (epidural) anesthesia
technique and the reason for its selection was explained to the patient and
his co-operation requested.
No premedication was advised. Intravenous access was established
with a 18 G cannula and lactated ringer solution administered at the rate
of 1.5ml /kg/hr.
Non-invasive blood pressure (NIBP) (every 5 min), arterial oxygen
saturation (SpO
throughout the surgery. CVP line was inserted peripherally through the
basilic vein.
After taking all aseptic and antiseptic precautions, an 18 G epidural
catheter was introduced at L3-4 space. 2% xylocaine plain (without
adrenaline) was injected slowly to attain a sensory and motor block up to
T10 level. BP of 70 mmHg systolic was observed after 10 min. This was
treated with intermittent bolus of ephedrine in doses of 2.5 to 5 mg. The
2) and lead II of the electrocardiogram were monitoredaim was to maintain the systolic BP of 90 mmHg. or more. Ventricular
premature beats seen on the EKG were not persistent enough to warrant
treatment.
Central venous pressure ranged between 8-9 cmH
Intraoperative blood loss was about 300-350 ml as judged by the
collection in suction bottle and the soaked gauze pieces. Surgery lasted
for 90 min.
Postoperatively, there was a drop in the blood pressure to 76/40
mmHg, CVP was 3 cm H
sweating or difficulty in breathing. Fluid administration continued at the
rate of 75ml/hr. Dobutamine infusion was started at the rate of 7.5
ug/kg/min,to maintain the systolic blood pressure to 90 mmHg. After 1
hour, ventricular bigemini rhythm was seen on the monitor, which
was successfully treated by administering amiodarone. Repeat Hb value
was 7.3 gm%.
1 unit of fresh blood was transfused.
2O.2O. Patient had no complaints of chest pain,The subsequent postoperative course was uneventful. The patient is
doing fine and visits the OPD for regular follow up.
