Cesarean section supine position hypotension syndrome preventing bracket

Abstract

The present invention discloses a cesarean section supine position hypotension syndrome prevention bracket, which can effectively prevent a vertebral canal anesthesia downlink cesarean section parturient hypotension syndrome and avoid complications of a fetus and a pregnant woman caused by hypotension. The instrument is developed according to a special anatomy structure of a parturient and includes a backing plate, a left and a right support plates and support plate adjusting devices. The left and the right support plates are supported by the support plate adjusting devices, which are respectively arranged on the two ends of the backing plate. The width, the height and the angle of the supporting plates can be adjusted according to the plumpness and the slenderness of the parturient and the size of a uterus. The device is arranged under the waist of the parturient when in use. A hand wheel is shaken to regulate the device to be fit for the size of the pregnant woman. A sponge support clings tightly to the abdomen of the pregnant woman and lifts the uterus. The compression effect on a lower cavity vein is rescinded. And the repenting blood volume of the parturient is kept stable. The hypotension generation rate is reduced. The safety of the fetus and the pregnant woman can be ensured. The success development of the instrument provides the cesarean section operation with convenient conditions. And the present invention has the advantages of safety, practicality and convenient adjustment, which is suitable for the extension and the use.

Description

technical field [0001] The invention relates to an anesthesia auxiliary device for clinical cesarean section in obstetrics and gynecology, in particular to a bracket for preventing hypotension syndrome in the supine position during cesarean section. Background technique [0002] Supine hypotensive syndrome (SHS) is a serious complication in cesarean section. With the decrease of blood pressure, acute fetal distress and neonatal asphyxia may occur, and severe cases may endanger the life of mother and baby. The main clinical manifestations of supine hypotension syndrome in patients undergoing cesarean section under spinal anesthesia are dizziness, irritability, nausea, vomiting, pale complexion, cold sweat, rapid pulse, and drop in blood pressure immediately after the pregnant woman lies on her back after anesthesia. Generally, the systolic blood pressure drops by 30mmHg or below 80mmHg, and some patients even drop below 50mmHg. As the blood pressure drops, the fetus is also a...

Problems solved by technology

Preventive measures generally make the pregnant woman take the left lying position or tilt the operating bed 15 degrees to the left (Chinese Journal of Misdiagnosis, Vol. Balloons under the buttocks to prevent, but the effect is not ideal

Elevation on the left side of the pregnant woman or left tilting of the operating bed can not relieve the compression of the inferior vena cava from the uterus, but also affect the spread of anesthesia and surgical operations, and increase the fear of pregnant women

The balloon under the buttocks makes the pregnant woman's position difficult to stabilize, and the balloon is easy to be squeezed out

Some foreign scholars used Meta-analysis to study the effect of preventive application of ephedrine on the prevention and treatment of supine hypotension syndrome, and found that the preventive application of ephedrine not only cannot effectively prevent, but also can cause complications such as hypertension (Anesth Analg 2004; 98: 483- 90)
