Bibliometric Analysis of Anesthetic Drugs' Effects on Immune Function- Current Knowledge, Hotspots and Future Perspectives

Objective

The objective of this study is to conduct a bibliometric analysis of the present status, areas of focus, and upcoming developments in the research of anesthetic drugs and their impact on immune function, along with other related research domains.

Methods

From January 1, 2008 to June 9, 2023, A thorough exploration of anesthetic drug-related literature pertaining to immune function was carried out through the utilization of the Web of Science. The bibliometric analysis was predominantly executed by means of CiteSpace, GraphPad Prism 8.0, and the acquisition of data regarding the country, institution, author, journal, and keywords associated with each publication.

Results

This study analyzed a comprehensive total of 318 publications, consisting of 228 articles and 90 reviews, to determine the publication output of anesthetic drugs on immune function. Notably, China exhibited the highest publication output with (109, 34.28%) articles. Among the institutions analyzed, Harvard University was found to be the most productive with (12, 3.77%) publications. The study findings indicate that Buggy, Donal J (5, 1.57%) and Yuki, Koichi (5, 1.57%) had the highest publication records. Anesthesiology was the most frequently cited journal with a total of (206) citations. The results also revealed that "surgery" was the most frequently used keyword, appearing (48 times), followed by "general anesthesia" (41 times) and "breast cancer" (37 times). The study has identified several current areas of interest, with a particular emphasis on "metastasis", "inflammation", "recurrence", "anesthesia technique", and "induction". It is anticipated that forthcoming research endeavors will concentrate on exploring the impacts of isoflurane, sevoflurane, and ketamine on immune function.

Conclusion

This study provided a thorough analysis of the research trends and developments in investigating the impact of anesthetic drugs on immune function, incorporating pertinent research and collaborative entities such as authors, institutions, and countries.

Surgical stress and postoperative complications related to regional and radical mastectomy in dogs

Background

Surgery is the treatment of choice for regional control of mammary neoplasms in female dogs. Various surgical techniques may be used, as long as mammary gland anatomy, lymphatic drainage, and known prognostic factors are respected. The purpose of this study was to compare surgical stress—including duration of surgery, nociception and hematological changes—and postoperative complications in dogs undergoing regional and unilateral radical mastectomy. Eighteen dogs were selected for each technique. Postoperative pain (nociception), hematological changes, and postoperative complications were compared between the two groups.

Results

The group treated with radical mastectomy had a longer surgical duration, showed more intense physiological changes, achieved higher scores on nociception scales, and experienced more postoperative complications.

Conclusion

Compared to regional mastectomy, radical mastectomy was associated with longer surgical duration, greater nociceptive stimulus, greater surgical stress, and higher incidence of postoperative complications in dogs. Although evaluation of long-term results was not a goal of this study, it is suggested that postoperative recovery and patient quality of life should be considered when choosing a surgical approach for treating mammary tumors in dogs.

Evaluation of the function of polymorphonuclear neutrophilic leukocytes in healthy dogs given a high dose of methylprednisolone sodium succinate

OBJECTIVE

To evaluate effects of a high dose of methylprednisolone sodium succinate (MPSS) on function of polymorphonuclear neutrophilic leukocytes (PMNs) in dogs.

ANIMALS

7 healthy male Beagles (body weight, 10.5 to 15 kg; age, 2 to 4 years).

PROCEDURES

All dogs were treated by IV administration of a high dose of MPSS (30 mg/kg). Additional doses of MPSS (15 mg/kg) were administered IV at 2 and 6 hours and then at 6-hour intervals until 48 hours after the initial dose. Blood samples were collected before and 1, 2, 4, 7, and 14 days after completion of the MPSS administrations and used for evaluation of PMN functions. Isolated PMNs were used for assessment of functions, such as adhesion, migration, phagocytosis, and oxidative burst.

RESULTS

On days 1, 2, and 4 after completion of MPSS administration, there was a decrease in PMN expression of adhesion markers such as CD11b and CD18. There was a decrease in the phagocytotic ability of PMNs on days 1, 2, and 7 after completion of MPSS administration, with a reduction in the oxidative burst of PMNs detected on day 7. No significant changes were identified for migration. All functional changes returned to their pretreatment values by 14 days after completion of MPSS treatment.

CONCLUSIONS AND CLINICAL RELEVANCE

Treatment with a high dose of MPSS suppressed PMN functions in dogs. Analysis of these results suggested that treatment with a high dose of MPSS can suppress some of the major functions of PMNs for at least 7 days.
