Postoperative patient-controlled epidural analgesia clinical observation uses the visual analog score, with the score ranging from 0 to 10: 0 ~ 1 points indicate painless, 2 ~ 3 for mild pain, 4 to 6 for moderate pain, and > 7 points for severe pain. After surgery, factors such as blood pressure, breathing, nausea, vomiting, urinary retention, and the recovery time of gastrointestinal peristalsis (anal exhaust time) are monitored. The results of the comparison of analgesic effects between the two groups show that the PCEA group has obvious superiority, with a very significant difference (P < 0.01), as shown in Table 1. The postoperative complication rate was 13.3% in Group I and 36.7% in Group II (P < 0.05), with Group I showing significantly faster intestinal peristalsis recovery than Group II (P < 0.01), as shown in Table 2.
The surgical trauma and postoperative pain are harmful stimuli that can seriously damage the physical and mental health of patients, causing nausea, vomiting, slowed bowel movements, muscle spasms, thrombosis, cardiac and pulmonary complications, and delayed organ function recovery. Apart from operative factors and patient conditions, postoperative pain and stress response are key factors leading to postoperative complications. Anesthesia can block the pain reflex arc at different levels, thereby weakening or blocking strong stress responses. Therefore, more attention is paid to the application of anesthesia techniques and analgesic drugs to provide effective postoperative analgesia for patients and promote their rehabilitation.
In the table after L, the PCEA group showed better analgesic effects compared to the pethidine intramuscular group, * P < 0.01. Postoperatively, the PCEA group and the meperidine intramuscular group were compared regarding adverse reactions, intestinal motility recovery time, respiratory inhibition, decreased blood pressure, nausea, vomiting, and urinary retention. Compared with Group A, P < 0.01. PCEA provides safe and reliable postoperative analgesia, reducing the abuse of large doses of traditional intermittent intramuscular analgesics; during L EA, there was no significant effect on respiration and circulation, and complications were significantly lower in the PCEA group than in the intramuscular pethidine group. PCEA can induce early recovery of peristalsis, reduce the incidence of postoperative abdominal distension, allow early feeding for patients, and is conducive to patient rehabilitation. As a result...
