Evaluation of the Effects of Using an Invented Lamp Attached to an Anesthetic Machine for Eye Surgery in the Dark Operating Room

Abstract

Background and objective:  Certain eye surgery needs to be operated in dark operating room. As The Anesthetic device called “Datex – Ohmeda, Excel 210 SE Type” employed by the operating team is not equipped with a lamp, a torch is used during   the anesthetic phase and the subsequent monitor. This may not be convenient nor effective. Due to this difficulty, the researchers invented a lamp attached to the anesthetic machine by applying a spotlight lamp with clamps which is practically available and easy to make.  This lamp can provide sufficient light for the anesthetic team to effectively monitor the patients. This study aimed to evaluate the degree of effectiveness of the use of an invented lamp attaching to an anesthetic machine compared with the experience of using a conventional touch in a dark operating room.

Methods:   The  research  was descriptive  using a questionnaire  to collect  data  from  30 respondents which consisted  of  anesthesiologists, anesthetic residents,  nurse anesthetists and nurse anesthetist trainees.  The  respondents  were asked  to  evaluate the 4 aspects namely  1) convenience in using the lamp  2) amount of light   3) convenience  in monitoring  patient   4)  overall  satisfaction . The  evaluating  scale included  the followings : 3 = much better , 2 = slightly better , 1= no change ,  0 = worse  than a conventional torch. Eight ophthalmologists were  asked to identify whether the light from  the  invented lamp  disturbed the operation  procedure .                                           

Results:   Using an attached lamp was significantly better than using a conventional torch in all aspects particularly its convenient use (  = 3.00 ). The average score for each aspect was highly favorable with at least 2.93. All the ophthalmologists agreed that the light from the  invented lamp  did not disturbed the operation  procedure at all .       

Conclusion:  Using an attached lamp in a dark operating room during the eye surgery is much more effective than using a convenience torch.
