An insufflator is a device that delivers gas into the abdominal cavity to lift the abdominal wall, create the necessary space, and then maintain the set pressure during surgery. The insufflator has a control panel that allows you to adjust the following functions: - Maintaining constant intra-abdominal pressure (from 1 to 30 mmHg). - Switching the gas supply rate (from 1 to 40 liters per minute). - Indication of the set pressure. - Indication of actual intra-abdominal pressure. - Indication of the set gas supply rate. - Indication of the actual gas supply rate. - Indication of the amount of gas consumed. - Turning on the gas supply. - Indicators for gas supply interruption, hose compression, and emergency. The latest generation insufflator requires virtually no adjustments or switching during surgery. The insufflator automatically maintains the set pressure in the patient's abdominal cavity, adjusts the gas flow rate depending on the leak rate, and provides visual and audible signals for all emergency situations during the procedure (lack of gas in the cylinder, hose rupture, hose compression, etc.). For operative surgery, an insufflator with a gas flow rate of at least 15 L/min is required. For major interventions (e.g., amputation or hysterectomy), a more powerful insufflator with a gas flow rate of 25 L/min or more is required. This is essential for maintaining the necessary space when changing instruments, inserting staplers, using a morcellator, removing a drug, or performing significant aspiration during bleeding—that is, in all situations that result in a significant gas leak and require rapid gas replenishment. The insufflator is controlled from the control panel. Proper operation of the insufflator is absolutely essential for patient safety and the successful completion of the laparoscopic procedure. Insufficient gas supply will not create the necessary space, and an uncontrolled increase in intra-abdominal pressure above 15 mmHg, even for a few minutes, can lead to cardiovascular and pulmonary dysfunction and, under certain conditions, the development of complications such as pneumothorax, pneumomediastinum, subcutaneous emphysema, and gas embolism. The choice of insufflation gas requires separate discussion. In the West, inert gases, although expensive, are the most popular. In our country, the choice is typically between nitrous oxide, carbon dioxide, and operating room air. Nitrous oxide is practically abandoned because it supports combustion and can ignite during electrosurgical intervention. Furthermore, it is absorbed by the peritoneum and affects the controllability of anesthesia. Carbon dioxide supplied to the insufflator from a cylinder is preferable in all respects. It is flame-retardant, readily available, inexpensive, and dissolves quickly in the blood, reducing the risk of gas embolism when entering the bloodstream. Operating room air, supplied to the insufflator via a special compressor, can also be used in laparoscopy; however, it causes significant smoke during electrosurgical interventions because it contains oxygen. Furthermore, air dissolves poorly when entering the bloodstream, which in certain cases increases the risk of gas embolism. Air contains 80% nitrogen, which is very slowly absorbed by the peritoneum after surgery, causing patient discomfort and interfering with postoperative ultrasound examinations.
