Study on analgesia technique for artificial abortion

Nowadays, more and more women are experiencing unexpected pregnancies. Among the abortion procedures for terminating pregnancy, painless abortion is one of the operations that women need to trust more. Therefore, in recent years, the medical requirements for painless abortion have been increasing. Experts have done a lot of research to reduce patients' pain, ensure the smooth progress of the operation, and improve the quality of delivery. The following is some research on abortion analgesia technology.

1. General data. This group of 90 patients, aged 17-42 years, average (32.5±3.7) years old, normal intrauterine pregnancy was confirmed by routine leucorrhea examination, B-ultrasound examination, gynecological examination, etc. Gestational age was 5-11 weeks, with an average gestational age of (7±0.8) weeks. Patients with a history of drug allergy and severe diseases of other systems such as heart, lung, and kidney were excluded. They were randomly divided into group A, group B, and group C, 30 cases each. There was no statistically significant difference in general data such as age and gestational age among the three groups (P>0.05), and they were comparable.

2. Methods. 30 cases in group A underwent routine blood and urine routine, B-ultrasound, electrocardiogram, four coagulation tests, and bimanual examination before surgery. Patients with contraindications to surgical anesthesia were excluded, and no food was allowed 4-6 hours before surgery. The bladder lithotomy position was taken, and the patients were instructed to spread their legs. After proper fixation, the heart rate, blood pressure, respiration, blood oxygen saturation, and electrocardiogram were monitored simultaneously. The intravenous channel was opened, and oxygen was continuously inhaled. Routine disinfection was performed. First, fentanyl 0.002 mg/kg was slowly injected intravenously, and propofol was injected intravenously 2 minutes later. The induction dose was 2 mg/kg. Artificial abortion was performed after the patient's eye blink reflex completely disappeared. The patient's reaction during the operation was observed, and fentanyl 20-30 mg was added as needed. 30 cases in group B were routinely disinfected and draped, and lidocaine 2.5 ml was injected at 3 o'clock and 9 o'clock of the cervix, respectively, and the operation was performed after local block anesthesia. 30 cases in group C underwent traditional abortion. No analgesics were used during the perioperative period. Verbal communication and comfort were strengthened to distract the patients' attention in order to relieve the pain and reduce tension.

3. Observation indicators. Observe the effect of artificial abortion, intraoperative bleeding, and analgesic effect. Abortion effect: Complete abortion: The villi, embryos and their tissues are completely and cleanly aspirated; Incomplete abortion: A second surgical curettage is required because of the villi and other defects left in the uterus, or the embryos and their tissues are not completely aspirated; Failed abortion: Postoperative uterine infection, artificial abortion syndrome, intraoperative hemorrhage or intrauterine adhesions, etc. Intraoperative bleeding: If the blood volume in the negative pressure bottle is >30ml, it is considered excessive bleeding.

4. Analgesic effect. Significant effect: no consciousness and abdominal pain, quiet eye; effective: the patient is basically quiet, with a slight distending pain in the lower abdomen; ineffective: the patient groans loudly or is not quiet enough, has a painful expression, and feels pain in the lower abdomen

5. Statistical analysis: SPSS13.0 statistical software was used, and the measurement data between groups were expressed as (X±S). The measurement data were subjected to t test, and the counting data were subjected to Chi-square test. P<0.05 was considered statistically significant.

Artificial abortion is a remedial measure for family planning and is more common in obstetrics and gynecology. In recent years, the public has higher requirements for the quality and comfort of medical services. Patients are more likely to accept painless abortion under anesthesia, which reduces the incidence of adverse stress reactions in various systems of the body caused by pain, reduces myocardial oxygen consumption while relieving pain, and is of great significance to ensuring surgical treatment.
