Laserscope GreenLight HPS, Руководство оператора

Страница: 47 / 74

• The surgeon should become fully acquainted with the unique surgical
effects produced with the GreenLight HPS
™
laser system prior to clinical
use. These effects include coagulation, depth of penetration, and cutting
intensity.
• Prior to turning the laser system on, operating room personnel and the
patient should be wearing protective eyewear suitable for 532nm laser
energy.
• Laserscope has no clinical information or experience concerning the use of
Laserscope’s laser systems on pregnant women or nursing mothers.
• The risk of combustion, perforation, and laser-induced hemorrhage, all of
which could cause serious or fatal complications, must be fully explained
to the patient.
• As with conventional endoscopic treatment, adverse reactions such as
fever, chills, sepsis, edema and hemorrhage may occur following laser
treatment. In extreme cases, death may occur due to procedural
complications, concurrent illness, or the application of the laser. In the
case of the treatment of BPH, reported adverse events have been:
decreased or retrograde ejaculation; urinary retention; bladder neck
contracture; urethral strictures; hematuria; renal insufficiency;
incontinence; potential for re-treatment and shortness of breath.
• Use of lower power levels and shorter exposure times are required in
order to prevent thermal damage to underlying structures; for example,
to thin-walled structures, such as the bladder.
•
The surgeon should carefully assess the target and surrounding tissue.
Then begin at the lowest power, with short duration exposures. Note the
surgical effect and adjust the settings until the desired effect is obtained.
• Before operating the laser system, surgeons and all staff operating the
laser should carefully read and become familiar with the Operator’s
Manual.
• Careful assessment of the target and surrounding tissue should be made,
and appropriate power should always be used.
• Tissue perforation can occur if excessive laser energy is applied. This can
occur through the use of excessive laser power or the application of power
for excessive periods of time, particularly on diseased tissue.
• Aim and use the laser only on tissues that are in full view.
• Extra caution should be used when lasing tissue in close proximity to
known arteries, nerves and veins.
• Flash fires can occur. A basin of water should be available in case a fire
should occur.
• The laser may not be effective for coagulation in massive hemorrhage
situations. The surgeon must be prepared to control hemorrhages with
