Abstract
OBJECTIVE: Presence of autonomic neuropathy in diabetic patients can alter the haemodynamic response to induction and tracheal intubation. This trial was conducted to compare this response in 30 non-diabetic (control group) and 30 diabetic patients including both insulin and non-insulin dependent.
METHODS: A prospective, age matched case controlled study was conducted at the Aga Khan University Hospital, for one year. After pre-medication with tablet midazolam 7.5 mgs orally, patients received pethidine 0.8 mg kg(-1), thiopentone sodium 4 to 5 mg kg(-1) for induction and vecuronium 0.1 mg kg(-1) to facilitate tracheal intubation. Following manual ventilation with isoflurane 0.8% in oxygen 33% and nitrous oxide 66%, laryngoscopy and tracheal intubation was performed. Blood pressure (systolic, diastolic and mean) and heart rate responses were measured for 10 minutes.
RESULTS: The systolic arterial pressure dropped by 9% after induction and rose by 16% after intubation in nondiabetics compared to 12% drop after induction and a rise of 10% after intubation in diabetics. No difference was seen in diastolic blood pressure which increased by 27% in ND compared to 22% in DB groups. The heart rate rose by 27% in non-diabetics compared to 17% in diabetics after intubation.
CONCLUSION: The systolic, diastolic and mean blood pressure response was similar in the two groups. A greater fall in SAP was observed post intubation in the DB group. A significant difference was observed in the heart rate response which was less in the diabetic group.
