Purpose: A prospective randomised case control study was conducted to evaluate the stress induced in patients during minor oral surgical procedures based on the variations in blood glucose levels, blood pressure and pulse rate and thereby to assess the relation between stress and the aforesaid parameters.
Materials and methods:A total of 100 subjects who required routine minor oral surgical procedures were randomly divided into two equal groups with subjects of test Group I receiving 2 % lignocaine with adrenaline, subjects of control Group II received the same with an added oral intake of 10 mg glucose in 200 ml water after administration of local anaesthesia. The blood glucose level, blood pressure, and pulse rate were recorded before the commencement of procedure with the patient on the chair, before and immediately after local anaesthetic administration, finally after the procedure, and the obtained data was statistically analysed.
Results:The blood glucose levels were found to decline at a point before extraction and then increase to a value higher than the preoperative value in group I, while in groups II the blood sugar values maintain a steady state without decline, until it progressively increases to a higher post-operative value. In all groups blood pressure was found to elevate progressively and an increase in pulse rate was observed in all stages till the administration of LA after which there was a marked decline.
Conclusion:Our results point towards the phenomenon of a short lasting decline in blood glucose levels for a period of not more than four or five minutes before an elevation in blood glucose levels. In minor oral surgical procedures under local anaesthesia, this momentary hypoglycaemia is of great clinical significance as even moderate hypoglycaemia can lead to episodes of psychogenic syncope.
