Background and Aims:

Identification of the mid-line for central neuraxial blocks by palpatory methods in morbidly obese patients is near impossible. The study is aimed at identifying the impact of anxiety on self awareness of ones body in morbidly obese patients with BMI more than 45.

Methods:

Patients who were admitted for incidental surgery, were randomly allocated to two different groups and asked to identify the mid-line of their lumbar spine. The same finding was confirmed using ultrasound imaging of the lumbar spine and the deviation from the actual location was noted.

Patients were randomly allocated in two groups. Group A, the procedure was done in the preoperative period (prior to the day of surgery) and in the other group B in the immediate preoperative period (in the preoperative area in operation theatre).

In both the groups we assessed their Beck Anxiety Inventory score to evaluate if anxiety caused a difference in the patient ability to identify the mid-line.

Results:

57.69%  out of 26 obese patients were able to identify the mid-line of their back accurately within 5 mm and 100% within 10 mm range. Only 1 patient out of 26 (3.8%) had moderate anxiety and as per the unpaired T test, P value is 0.873 and the difference is not significant.

Conclusions:

In conclusion, the results show that anxiety is not a confounding factor and morbidly obese patients can identify the mid-line of their back correctly.
