Propofol based total intravenous anesthesia versus sevoflurane based inhalation anesthesia: The postoperative characteristics in oral and maxillofacial surgery

The clinical effect of sevoflurane anesthesia with laryngeal mask airway in the extraction of teeth in children

Objective

To evaluate the effect of sevoflurane general anesthesia with laryngeal mask airway in the extraction of teeth.

Methods

A retrospective analysis was performed on 88 children who underwent extraction of teeth in the Department of Anesthesiology of our hospital from June 2022 to April 2023, including 44 patients who received traditional anesthesia as the control group and 44 patients who received laryngeal mask airway sevoflurane general anesthesia as the observation group. Anesthesia and operation records of patients in the two groups were analyzed, including intraoperative vital signs, anesthesia induction time, recovery time of spontaneous breathing, first feeding time within 24 h after surgery, postoperative pain score, incidence of adverse reactions, Ramsay score and wake agitation, and other indicators were collected, and statistical analysis was conducted.

Results

The recovery time of the observation group was 7.88 ± 4.95 min, and the recovery time of spontaneous respiration was 10.58 ± 3.64 min, which were significantly shorter than 15.23 ± 5.12 min and 14.41 ± 3.56 min of the control group (P < 0.001). There were no significant differences between the two groups in anesthesia induction, operation duration and first feeding time within 24 h after operation (P > 0.05). There was no significant difference in postoperative pain scores between the two groups (P > 0.05). The overall incidence of adverse reactions was 6.82% in the observation group compared with 22.73% in the control group (χ² = 4.423, P = 0.035). In addition, the Ramsay score of the observation group was significantly improved compared with the control group (P < 0.05), and the incidence of agitation during the recovery period was also significantly decreased (P < 0.05).

Conclusion

Laryngeal mask airway sevoflurane anesthesia can significantly accelerate the recovery process of children after extraction of teeth, and reduce the occurrence of adverse reactions, providing a safer and more efficient choice than traditional anesthesia.

Delirium in older patients given propofol or sevoflurane anaesthesia for major cancer surgery: a multicentre randomised trial

BACKGROUND

Delirium is a common and disturbing postoperative complication that might be ameliorated by propofol-based anaesthesia. We therefore tested the primary hypothesis that there is less delirium after propofol-based than after sevoflurane-based anaesthesia within 7 days of major cancer surgery.

METHODS

This multicentre randomised trial was conducted in 14 tertiary care hospitals in China. Patients aged 65-90 yr undergoing major cancer surgery were randomised to either propofol-based anaesthesia or to sevoflurane-based anaesthesia. The primary endpoint was the incidence of delirium within 7 postoperative days.

RESULTS

A total of 1228 subjects were enrolled and randomised, with 1195 subjects included in the modified intention-to-treat analysis (mean age 71 yr; 422 [35%] women); one subject died before delirium assessment. Delirium occurred in 8.4% (50/597) of subjects given propofol-based anaesthesia vs 12.4% (74/597) of subjects given sevoflurane-based anaesthesia (relative risk 0.68 [95% confidence interval {CI}: 0.48-0.95]; P=0.023; adjusted relative risk 0.59 [95% CI: 0.39-0.90]; P=0.014). Delirium reduction mainly occurred on the first day after surgery, with a prevalence of 5.4% (32/597) with propofol anaesthesia vs 10.7% (64/597) with sevoflurane anaesthesia (relative risk 0.50 [95% CI: 0.33-0.75]; P=0.001). Secondary endpoints, including ICU admission, postoperative duration of hospitalisation, major complications within 30 days, cognitive function at 30 days and 3 yr, and safety outcomes, did not differ significantly between groups.

CONCLUSIONS

Delirium was a third less common after propofol than sevoflurane anaesthesia in older patients having major cancer surgery. Clinicians might therefore reasonably select propofol-based anaesthesia in patients at high risk of postoperative delirium.

Application of Intravenous Anesthesia in Laparoscopic Hiatal Hernia Repair of Children

In order to solve the stress problem in laparoscopic hiatal hernia repair of children, improve surgical safety, and reduce surgical risk, this study compared the perioperative changes of epinephrine, norepinephrine, IL-6, IL-10, and hemodynamics in children undergoing laparoscopic surgery under intravenous general anesthesia and general anesthesia combined with an epidural block. In this study, 40 children aged 1-3 years who planned to undergo laparoscopic ortopexy and those who planned to undergo laparoscopic high ligation of hernia sac, aged 23.84 1.6 months and weighed 14.9 1.1 kg, were randomly divided into general anesthesia combined with the epidural block group (group A) and a total intravenous anesthesia group (group B), with 20 subjects in each group. The results are as follows: There were no differences in age, gender, body weight, anesthesia time, pneumoperitoneum duration, and functional time between the two groups. Cytokines: Compared with T0, the levels of IL-6 in T2, T3, T4, and T5 groups were significantly increased (P < 0.01). IL-10 levels: T2, T3, T4, and T5 groups were further increased, and the difference was statistically significant compared with T0 (P < 0.01). There was no difference between groups (P > 0.05). The recovery time in group B was shorter than that in group A (P < 0.01), and the total amount of propofol and fentanyl in group B was less than that in group A (P < 0.01). Through research on intravenous anesthesia treatment, it has been proved that total intravenous anesthesia can relieve perioperative pressure, reduce intravenous injection, and reduce the recovery time of children. However, its effect on cytokines is not obvious, so intravenous anesthesia is the most appropriate anesthesia mode in laparoscopic hiatal hernia repair surgery, which has practical significance.

Assessing Postoperative Recovery With Volatile Gas Versus Total Intravenous Anesthesia in Patients With and Without Obstructive Sleep Apnea

INTRODUCTION

To determine if there is a recovery time difference between patients with and without obstructive sleep apnea (OSA) when using total intravenous anesthesia (TIVA) compared to volatile gas inhalational anesthesia.

PATIENTS AND METHODS

OSA and Non-OSA patients were identified at a tertiary institution between January 2019 and November 2020. Non-OSA patients were defined as those who have not been formerly diagnosed with OSA. A modified STOP-BANG score (MSBS) was performed to screen Non-OSA patients for OSA. Recovery was measured by Phase I recovery time, or time it took a patient to reach ≥9/10 on the Aldrete scoring system.

RESULTS

A total of 334 patients were included with 142 in the OSA cohort (59 TIVA, 83 inhalational anesthesia) and 192 in the Non-OSA cohort (119 TIVA, 73 inhalational anesthesia). In OSA patients, there was a 41.29-minute recovery time reduction when using TIVA versus sevoflurane (P < .0001). Non-OSA patients recovered faster than OSA patients when undergoing inhalational anesthesia by 46.76 minutes and TIVA by 18.58 minutes (P < .0001 and P = .0907, respectively). Non-OSA patients with a MSBS < 3 and ≥3 had a shorter recovery time compared to OSA patients when both underwent sevoflurane anesthesia (57.27 minutes, P < .0001 and 56.23 minutes, P = .040, respectively). Non-OSA patients with a MSBS of <3 had a decrease in recovery time of 26.68 minutes when compared to OSA patients who underwent TIVA (P = .0004).

CONCLUSIONS

When utilizing TIVA over inhalational anesthesia, patients with OSA have significantly increased benefit in terms of reduced Phase I recovery times as compared to Non-OSA patients.

Therapeutic Perspectives for the Perioperative Period in Oral Squamous Cell Carcinoma (OSCC)

The perioperative period is the relatively short window of time, usually measured in days or weeks, around the surgical procedure. Despite its short duration, this time period is of great importance for cancer patients. From a biological point of view, the perioperative period is complex. Synchronous with primary tumor removal, surgery has local and distant consequences, including systemic and local inflammation, coagulation and sympathetic activation. Furthermore, the patients often present comorbidities and receive several medical prescriptions (hypnotics, pain killers, anti-emetics, hemostatics, inotropes, antibiotics). Because of the complex nature of the perioperative period, it is often difficult to predict the oncological outcome of tumor resection. Here, we review the biological consequences of surgery of Oral Squamous Cell Carcinoma (OSCC), the most frequent form of primary head and neck tumors. We briefly address the specificities and the challenges of the surgical care of these tumors and highlight the biological and clinical studies that offer insight into the perioperative period. The recent trials examining neoadjuvant immunotherapy for OSCC illustrate the therapeutic opportunities offered by the perioperative period.
