Laparoscopic Sterilization Under Local Anesthesia with Conscious Sedation Versus General Anesthesia: Systematic Review of the Literature

Outpatient percutaneous image-guided microwave ablation with monitored anesthesia care: An exploratory study

PURPOSE

To evaluate the feasibility, safety, and periprocedural perception of pain for a combination approach of moderate and deep sedation for image-guided percutaneous microwave ablation of both primary and secondary malignant lesions.

METHODS

This was a retrospective study of 33 image-guided percutaneous microwave ablation procedures performed on 33 patients in an outpatient-based interventional radiology center. We used a combination of midazolam, fentanyl, propofol, and/or ketamine to achieve mild to moderate sedation for the procedure, and also to achieve deeper sedation as needed for the ablation portion.

RESULTS

Technical success was achieved in all image-guided percutaneous microwave ablation procedures. Mean procedural time was 49.4 min. There were no major complications. Intraprocedural pain was absent in all patients. All 33 patients were deemed fit for discharge within 30 min following the procedure.

CONCLUSION

The combination approach of moderate and deep sedation for anesthesia during image-guided percutaneous microwave ablation is an advantageous option. This approach has a strong safety profile, good technical success, short procedure times, low levels of intraprocedural and post-procedural pain, and short recovery from anesthesia.

Non-Hormonal Contraception

While hormonal contraceptives are efficacious and available in several forms for women, perception of safety and concern over side effects are a deterrent for many. Existing non-hormonal contraceptives include permanent sterilization, copper intrauterine devices (IUDs), chemical/physical barriers such as spermicides and condoms, as well as traditional family planning methods including withdrawal and the rhythm method. Individuals who wish to retain their fertility in the future can achieve highest adherence and efficacy with long-acting, reversible contraceptives (LARCs), though there is only one, the copper IUD, that is non-hormonal. As rates of unintended pregnancies remain high with existing contraceptive options, it is becoming increasingly attractive to develop novel pregnancy prevention methods for both women and men. Non-hormonal contraceptives can target a variety of critical reproductive processes discussed here. This review focuses on identified non-hormonal contraceptive targets and subsequent drug candidates in development.

Procedural sedation and analgesia with propofol (PSA) for gynecologic surgery: A systematic review of the literature

OBJECTIVE

To identify which gynecologic procedures are eligible to be performed under PSA with propofol and to describe safety and effectiveness of these procedures in this setting.

METHODS

A systematic review of the literature was conducted in Pubmed (MEDLINE), Embase and The Cochrane Library from inception until September 21st 2022. Cohort studies and randomized controlled trials were included when they reported on clinical outcomes of gynecologic procedures under procedural sedation and analgesia in which propofol was used as an anesthetic. Studies were excluded when sedation without propofol was used, when they only mentioned the use of procedural sedation and analgesia but did not describe any clinical outcome parameters or when < 10 patients were included. The primary outcome parameter was completeness of procedure. Secondary outcome parameters were type of gynecologic procedure, intraoperative complication rate, patient satisfaction, postoperative pain, duration of hospital admission, patient's discomfort and ease of procedure as judged by the surgeon. The Cochrane risk of bias tool and the ROBINS-I tool were used for bias assessment. A narrative synthesis of the findings from the included studies was provided. Numbers and percentages were presented, as well as means with standard deviations and medians with interquartile range where applicable.

RESULTS

Eight studies were included. A total of 914 patients underwent gynecologic surgical procedures with procedural sedation and analgesia with propofol. Gynecological procedures varied from hysteroscopic procedures, vaginal prolapse surgery and laparoscopic procedures. The percentage of complete procedures was 89.8%-100%. Complications occurred in 0-6.5% of patients. Other outcomes were measured in various ways, but overall patient satisfaction was high and postoperative pain was low.

CONCLUSION

The use of PSA with propofol is promising for a wide range of gynecologic procedures, including hysteroscopic procedures, vaginal prolapse surgery and laparoscopic procedures. The use of PSA with propofol seems to be effective and safe and leads to high degree of patient satisfaction. More research is needed in order to determine for which types of procedures PSA can be used.

Pelvic floor reconstructive surgery under local anesthesia: A systematic review and meta-analysis

AIMS

The decision on the appropriate type of anesthesia for pelvic floor repair depends on a variety of factors including patients' age, performance status, comorbidities, cost-effectiveness and personal preferences. We aim to review the literature on urogynecological procedures performed under local anesthesia (LA).

METHODS

A systematic search of four electronic databases was conducted for articles published up to May 2020. Studies reporting outcomes of women who underwent pelvic floor reconstructive surgery under LA with or without sedation, were considered eligible.

RESULTS

Nineteen studies (14 noncomparative and 5 comparative), including 1626 cases of urogynecological procedures under LA were recruited. Meta-analysis revealed significantly lower mean pain scores in LA group compared to general-regional anesthesia one (GA/RA) at both 4-6 h and 8-18 h postoperatively (160 patients; mean difference [MD], -1.70; 95% confidence interval [CI]: -3.12, -0.28; p = 0.02 and 160 patients; MD, -0.72; 95% CI: -1.17, 0.27; p = 0.002, respectively). Pain scores at >24 h did not differ among the two groups (160 patients; MD, -0.28; 95% CI: -0.60-0.05; p = 0.10). Intra- and postoperatively morphine use was not different among patients who received LA and GA during prolapse surgery while nausea rates were significantly lower in LA group compared to RA group 8 h postoperatively.

CONCLUSIONS

LA with or without sedation represents a safe and efficient alternative anesthetic technique for urogynecological procedures with improved pain scores in up to 18 h postoperatively especially in patients who underwent surgery for SUI. LA is feasible and could be offered to patients undergoing pelvic floor surgery allowing a prompt postoperative recovery.

Comparison of the Effects of Thoracic Epidural Anesthesia with General Anesthesia on Hemodynamic Changes and its Complications in Patients Undergoing Laparoscopic Cholecystectomy

Background:

Epidural anesthesia (EA) today has been used extensively in surgical procedures and the management of pain associated with midwifery and chronic pain. This type of anesthesia can be done in different technical, physiological, and pharmacological ways. The aim of this study was to compare the effects of thoracic EA with general anesthesia (GA) on hemodynamic changes and its complications in patients underwent laparoscopic colonoscopy.

Materials and Methods:

This clinical trial study was conducted on 80 patients undergoing laparoscopic cholecystectomy with EA or GA based on inclusion and exclusion criteria. The patients were randomly divided into two groups of 40 and changes in blood pressure, systolic blood pressure (SBP) and diastolic blood pressure (DBP), heart rate (HR), and arterial blood oxygen saturation were measured. The incidence of nausea, vomiting, chills, and itching in the two groups was recorded. The analysis was performed descriptively and also using t-test and Chi-square tests.

Results:

The results showed that the mean of SBP and DBP, HR, and arterial blood oxygen saturation and the incidence of nausea and vomiting was statistically significant (P < 0.05) between the two groups at 4, 6, and 12 h after anesthesia and it was higher in a group of GA. There was no significant difference in shivering and itching between the two groups (P > 0.05).

Conclusion:

The results of this study indicated that thoracic EA in patients with laparoscopic cholecystectomy has significant effects on factors such as SBP and DBP and arterial blood oxygen saturation. Furthermore, EA has fewer complications than GA, and it is the preferable approach.
