RESUMEN
OBJECTIVE: To investigate the safety of etomidate anesthesia induction combined with Bispectral index (BIS) feedback closed-loop target-controlled infusion of propofol for spinal surgery in elderly patients. METHODS: Clinical data of 90 elderly patients who underwent elective spinal surgery were retrospectively analyzed. The patients were assigned to an etomidate group (n=48) and a propofol group (n=42) according to the different anesthesia methods. The etomidate group was anesthetized with etomidate combined with BIS feedback closed-loop target-controlled infusion, and the propofol group was anesthetized with closed-loop target-controlled infusion induced by propofol. The mean arterial pressure (MAP) and heart rate (HR) of the two groups were statistically analyzed 5 min after admission to the operating room (T0), the moment of the intubation (T1), 3 min after intubation (T2), 1 min before prone position (T3), 3 min after prone position (T4), the end of suture skin (T5) and 3 min after supine position (T6). In addition, the vasoactive drug application, awakening time, tracheal tube extraction time and incidence of postoperative complications were compared between the two groups. RESULTS: There were significant changes in MAP and HR from T0 to T1 in both groups (MAP: etomidate group t=5.677, P<0.001, propofol group t=8.093, P<0.001; HR: etomidate group t=2.731, P=0.008, propofol group t=3.967, P<0.001). MAP changes in etomidate group from T0 to T1 were less (MAP: t=4.236, P<0.001; t=2.082, P=0.040), and there was no significant difference in HR between the two groups (P>0.05). There were fewer patients receiving vasoactive drugs in the etomidate group (χ2=5.070, P=0.024), but no significant difference was found in the incidence of complications between the two groups, χ2=3.670, P=0.055. CONCLUSION: Compared to propofol, the application of etomidate combined with BIS feedback closed-loop target-controlled infusion in spinal surgery anesthesia for elderly patients can keep hemodynamics in a stable state, without affecting postoperative resuscitation, showing high safety, so it is worthy of clinical application.
RESUMEN
OBJECTIVE: To study the preventive effect of operating room nursing intervention on surgical incision infections in elderly patients undergoing orthopedic surgery. METHODS: Altogether, 128 orthopedic patients were divided into an observation group and a control group according to the nursing method each patient underwent, with 64 patients in each group. RESULTS: The grade A incision healing rate in the observation group was significantly higher than the rate in the control group (P<0.01). The eating and getting out of bed times, and the lengths of the hospital stays in the observation group were significantly shorter than the corresponding times in the control group (P<0.01). The incidences of postoperative wound infections in the observation group (0 cases) was significantly lower than the incidences in the control group (14 cases, accounting for 21.88%), and the difference was statistically significant (P<0.001). After the nursing, the prognoses and quality of life scores of the patients in the observation group were better than they were in the control group, and the differences were statistically significant (P<0.01). Our investigation indicated that, after the treatment, the overall patient satisfaction rate in the observation group (98.44%) was significantly higher than the patient satisfaction rate in the control group (84.38%), and the difference was statistically significant (χ2=27.349, P=0.000). CONCLUSION: Operating room nursing intervention can effectively prevent postoperative wound infections and promote incision healing, so it is worthy of application.
RESUMEN
Flavonoids are polyphenolic compounds that not only impart coloration to plants and fruits, but also protect plants from pathogens, radiation, etc. They serve as a nutrient to plants and possess immense anti-oxidant properties. Research has shown that they exhibit anti-inflammatory, anti-cancer, and neuroprotective properties in both in vitro and in vivo analyses. Luteolin is one such flavonoid belongs to the group of flavones present in herbs such as thyme, chamomile, celery, and green pepper. The epidemiological data on luteolin consumption show that luteolin has anti-inflammatory activity and protects from diseases associated with inflammation. The present study assessed the anti-nociceptive properties of luteolin, a potent anti-inflammatory agent, in mice. The results demonstrated that luteolin produces a significant and dose-dependent increase in hot plate latency and tail withdrawal time. It also reduced the number of abdominal constrictions and paw licking induced by acetic acid and glutamate, respectively. Luteolin inhibited the nociceptive responses in both phases of formalin test. The anti-inflammatory property of luteolin was also confirmed with different anti-inflammatory mice models induced by carrageenan and air pouch. Behavioral changes in luteolin-treated mice were assessed with open-field test to confirm the muscle relaxant property. The results of the current study from various pain and inflammatory models confirms that luteolin possess potent anti-nociceptive and anti-inflammatory properties and can thus be used as a drug in pain management.
