Post-operative haemorrhage after acute bilateral tonsillectomy in patients with peritonsillar abscess: prevalence, treatment, risk factors, and side of bleeding

Blood, Sweat, and Tonsils: Bleeding After Abscess Tonsillectomy for Quinsy-A Meta-Analysis

OBJECTIVE

Abscess tonsillectomy is performed during an active episode of quinsy. Apprehensions regarding an elevated bleeding risk have hindered its widespread acceptance. This study aims to assess the prevalence of post-tonsillectomy bleeding (PTB) associated with abscess tonsillectomy.

DATA SOURCES

A search was performed on August 27, 2023 in Medline, Embase, PubMed, Cochrane CENTRAL, and Web of Science databases.

REVIEW METHODS

The systematic review was conducted in adherence to the PRISMA guidelines. Pooled PTB rate was determined using a meta-analysis of proportions. The JBI tool was used to assess the quality of the included studies.

RESULTS

Of the 525 search records, 18 studies met the eligibility criteria for final analysis. These comprised of retrospective single-center analyses. The pooled prevalence of PTB was 6.65% (95% C.I. 4.01-9.81), and the return-to-theatre rate was 2.35% (95% C.I. 1.48-3.37). There was no difference in PTB rate between unilateral and bilateral tonsillectomy. However, the bipolar technique was associated with a higher PTB rate compared to cold steel dissection. The overall quality of the body of evidence was moderate.

CONCLUSION

Our study highlights the complications associated with abscess tonsillectomy. These findings contribute valuable insights into this potential treatment option for quinsy.

National survey on peritonsillar abscess treatment and attitudes toward quinsy tonsillectomy

OBJECTIVES

Peritonsillar abscess (PTA) is a common deep neck infection traditionally managed with conservative measures. Quinsy Tonsillectomy (QT) is recognized as a definitive treatment but remains variably utilized. We aimed to investigate PTA management strategies and attitudes toward QT among otolaryngologists.

METHODS

An anonymous questionnaire was distributed to members of the local national Society of Otolaryngology, evaluating treatment strategies based on patient characteristics and clinical scenario.

RESULTS

A total of 108 otolaryngologists responded (response rate: 30.8%). Participants preferred to treat PTA patients as inpatients (89%) and predominantly offered incision and drainage (I&D) as the first (90.7%) and subsequent (98.1%) treatment plan. QT was favored as a primary treatment only in 1.9% of responders. QT adoption increased with multiple I&D failures, reaching 95.3% after four attempts. In patients with recurrent PTA or tonsillitis, 84.2% preferred I&D follows by interval elective tonsillectomy, while 15% considered QT. The most common reason (72.2%) to avoid QT was the perception of a high perioperative risk.

CONCLUSION

I&D was favored for initial PTA treatment. QT is considered after multiple failed I&D attempts, and its use is limited as a primary treatment, mainly due to concerns regarding perioperative risk.

BiZact™ tonsillectomy: Predictive factors for post-tonsillectomy haemorrhage from a 1717 case series

OBJECTIVE

To determine primary and secondary post-tonsillectomy haemorrhage (PTH) rates and identify predictive factors in a cohort of consecutive adult and paediatric BiZact™ tonsillectomy cases.

SETTING

Retrospective cohort study. Patients from Flinders Medical Centre, Noarlunga Hospital and private otolaryngology practices who underwent BiZact™ tonsillectomy from 2017 to 2020.

DATA COLLECTED

patient age, indication for tonsillectomy, surgeon experience, time and severity of PTH, including return to theatre. Each secondary PTH was graded using the Stammberger classification. Logistic regression was utilised to identify predictors of secondary PTH.

RESULTS

One thousand seven hundred and seventeen patient medical records were assessed (658 adults and 1059 children). The primary PTH rate was 0.1%, and secondary PTH rate was 5.9%. The majority of secondary PTH cases were Stammberger grade A (80/102, 78.4%) requiring observation only. Few secondary PTH required medical intervention (grade B; 9/102, 8.8%), return to theatre (grade C; 12/102, 11.8%), or blood transfusion (grade D; 1/102, 1.0%), with no death reported (grade E; 0/102, 0.0%). Recurrent secondary PTH occurred in 8 patients (0.5%). Predictive factors of secondary PTH in children were surgeon experience with trainees having greater chance of PTH (OR 2.502, 95% CI 1.345-4.654; p = .004) and age of child (OR 1.095, 95% CI 1.025-1.170; p = .007). Surgeon experience was a predictive factor for adults (OR 3.804, 95% CI 2.139-6.674; p < .001).

CONCLUSIONS

BiZact™ tonsillectomy has a low primary PTH rate, with a secondary PTH rate comparable to other 'hot tonsillectomy' techniques. The majority of PTH events were minor and self-reported. There appears to be a learning curve for trainee surgeons.

Improving the recognition and management of hemorrhage: A scoping review of nursing and midwifery education

BACKGROUND

Hemorrhage is a frequent complication that nurses and midwives must recognize and manage to avoid life-threatening consequences for patients. There is currently no synthesis of evidence on educational interventions in nursing and midwifery regarding hemorrhage, thus limiting the definition of best practices.

OBJECTIVE

To map the literature on nursing and midwifery education regarding the recognition and management of hemorrhage.

DESIGN

Scoping review based on the Joanna Briggs Institute guidelines.

DATA SOURCES

Quantitative studies evaluating the effect of educational interventions with students, nurses, or midwives published in English or French, with no time limit.

REVIEW METHODS

Study selection, data extraction, and quality assessment were conducted by two independent reviewers. We characterized educational interventions based on the Guideline for Reporting Evidence-Based Practice Educational Interventions and Teaching. We categorized learning outcomes using the New World Kirkpatrick Model. Methodological quality appraisal was performed with tools from the Joanna Briggs Institute. Findings were synthesized using descriptive statistics and graphical methods RESULT: Most of the 38 studies used a single-group design (n = 26, 68%) and were conducted with professionals (n = 28, 74%) in hospital settings (n = 20, 53%). Most were of low (n = 14; 37%) or moderate (n = 18, 47%) methodological quality. Most interventions focused on postpartum hemorrhage (n = 34, 89%) and combined two or more teaching strategies (n = 25, 66%), often pairing an informational segment (e.g., lecture, readings) with a practical session (e.g., workshop, simulation). Learning outcomes related to the management (n = 27; 71%) and recognition of hemorrhage (n = 19, 50%), as well as results for patients and organizations (n = 9, 24%).

CONCLUSION

Considerable heterogeneity in interventions and learning outcomes precluded conducting a systematic review of effectiveness. High-quality, controlled studies are needed, particularly in surgery and trauma. Reflection on the contribution of nurses and midwives to the detection, monitoring, and management of hemorrhage could enrich the content and expected outcomes of hemorrhage education.

[Abscesstonsillectomy: Uni- or bilateral?]

OBJECTIVE

In addition to an empirical use of antibiotics for treatment of a peritonsillar abscess (PTA) there is a drainage of pus or the abscess tonsillectomy. Postoperative bleeding after abscesstonsillectomy (ABTE) is this surgery's most feared complication which can rarely lead to patients' deaths. The objective of this study was to compare bleeding complications of ABTE with and without contralateral tonsillectomy (TE) and to analyze the occurrence of a metachronous PTA at the contralateral side.

METHODS

Retrospective study of n= 655 patients undergoing ABTE with and without TE of the contralateral side from January 2004 to February 2019. Bleeding complications needing surgical hemostasis were analyzed regarding demographic and surgical parameters. In addition, occurrence of PTA and need for ABTE of the contralateral side after unilateral ABTE were evaluated.

RESULTS

Overall, 10/655 (1.5 %) patients presented with postoperative bleeding after ABTE. In 404/655 an ABTE with contralateral TE was performed. Here, 8/404 (1.98 %) patients showed contra- or bilateral bleeding. Only in 2/251 (0.7 %) patients occurred a bleeding complication after unilateral ABTE. Therefore, bleeding after unilateral ABTE was significantly lower than ABTE with contralateral TE (1.98 % vs. 0.7 %, p= 0.001). In 0.8 % of the patients a contralateral ABTE was necessary due to a metachronous PTA.

CONCLUSION

Overall, the rate of postoperative bleeding after ABTE (1.5 %) was low. Unilateral ABTE showed significantly lower postoperative bleeding rates compared to ABTE with contralateral TE. Consequently, the indication of a contralateral TE must be very strict.

Bipolar loop device versus bipolar diathermy for tonsillectomy: A pilot randomized controlled trial

OBJECTIVE

Tonsillectomy is one of the most common surgeries performed in the pediatric population. Although different forms of instruments and various methods are used to perform tonsillectomy, none of them is still recognized as the best global technique. This study aimed to compare the outcomes of the new Bipolar Loop tonsillectomy versus bipolar diathermy technique.

METHODS

This study is a pilot randomized clinical trial and was conducted on 40 pediatric patients who were the candidate of tonsillectomy. Patients were divided into two groups of Bipolar Loop or bipolar diathermy. Operation time, intraoperative bleeding, tonsillar fossa wound, postoperative complications, and duration of return to normal diet were evaluated in the current study.

RESULTS

In both of the Bipolar Loop and bipolar diathermy groups, no significant difference was found in terms of sex, age, and weight. The average amount of the operative time, intra-operative blood loss, and postoperative pain loss were significantly less in the Bipolar Loop group (P < .001). In addition, the tonsillar fossa wound healing scores were significantly better (on the 14th day, P = 0.009). However, there was no significant difference between the two groups in terms of postoperative bleeding, duration of return to a normal diet, and postoperative symptoms of fever, otalgia, or voice change between the groups.

CONCLUSION

The study showed that blood loss and postoperative pain through day 7 were significantly less in the Bipolar Loop group. Tonsillectomy with Bipolar Loop can be recommended as one of the methods for tonsillectomy, especially in pediatric patients.
