Lasers,dependent on their wavelength,can produce absorption,reflection,transmission,and scatter.The effect of scatter does not have any therapeutic benefit at this time and can be destructive to both staff and instruments.Select a safety measure that would prevent inadvertent scatter of laser energy during a surgical procedure.

Question

Quizplus · Accepted Answer

Special precautions should be followed when using the laser during an endoscopic procedure.When a laser fiber is introduced through the biopsy port of a flexible or rigid endoscope,the operator must view at least 1 cm of the tip of the fiber before activating the laser.If the end of the fiber is still within the sheath of the endoscope and the laser is fired,the heat from the laser energy quickly damages the optics and channel of the endoscope.A length of medical-grade tubing can be placed over the fiber with the tip recessed within the sheath,but tubing must be withdrawn sufficiently to expose the end of the fiber.
