Difference of delayed post-tonsillectomy bleeding between children and adults

The Utility and Safety of Prophylactic Tranexamic Acid in Tonsillectomy: A Systematic Review and Meta-analysis

OBJECTIVE

We conducted a systematic review of randomized controlled trials (RCTs) to evaluate the efficacy of tranexamic acid (TXA) in reducing posttonsillectomy hemorrhage (PTH).

DATA SOURCES

We searched MEDLINE, EMBASE, and CENTRAL for RCT comparing prophylactic TXA to control in patients undergoing tonsillectomy.

REVIEW METHODS

Per Preferred Reporting Items for Systematic Review and Meta-analysis guidelines, the databases were searched from date of inception through October 2023. RCTs of patients undergoing tonsillectomy or adenotonsillectomy and receiving prophylactic TXA versus control were included. Two reviewers screened citations, extracted data, assessed the risk of bias, and classification of Grading of Recommendations, Assessment, Development, and Evaluation independently. Standardized mean difference with 95% confidence interval (CI) was applied for continuous variables. Dichotomous data were expressed as relative risk with 95% CI.

RESULTS

A total of 10 RCT were included in our quantitative analysis. Eight studies reported on PTH rate. Prophylactic TXA showed non-significant decrease in PTH (relative risk or risk ratio [RR]: 0.62 [0.35, 1.10]). Sensitivity analysis showed significant decrease in PTH after exclusion of High-risk bias studies (RR: 0.48 [0.30, 0.77]). Intraoperative blood loss volume was significantly lower in the TXA group (35.59 mL [-48.19, -22.99]).

CONCLUSION

Overall, this study showed a tendency toward lesser PTH rate with prophylactic TXA. However, this tendency only reaches statistical significance when studies with high risk of bias are excluded. Well-designed trials are still needed to support our observations.

Treatment of Post-Tonsillectomy Hemorrhage With Nebulized Tranexamic Acid: Initial Investigation of a Novel Therapeutic Modality

OBJECTIVES

The use of nebulized tranexamic acid (TXA) in massive pulmonary hemorrhage is well-described. Published utilization in post-tonsillectomy bleeding (PTB) is limited to a single case. This study examines whether TXA resulted in change of operative intervention necessity and narcotic utilization.

METHODS

This was a retrospective cohort study at a single, urban academic medical center in the United States. Chart review was conducted of all patients who presented to the hospital for post-tonsillectomy bleed (PTB) between 3/1/2018 and 7/1/2020. Demographic data, intervention modality, need for control under general anesthesia, and opioid use were collected and analyzed.

RESULTS

Twenty-one patients underwent a total of 23 visits for PTB over the study period. Control of hemorrhage without need for operating room intervention for PTB was 100% (6/6) for patients receiving TXA nebulizer and 53% (9/17) for those receiving other treatment modalities. Opioid usage in hospital and on discharge was also lower in patients receiving TXA nebulizers. All results were statistically significant.

CONCLUSIONS

Our study supports nebulized TXA as an effective, non-invasive mode of hemostasis in patients presenting to the emergency department for post-tonsillectomy hemorrhage. Nebulized TXA may prevent the need for general anesthesia and operative intervention. Otolaryngologists should consider addition of this novel treatment appropriation of TXA to their management options for postoperative tonsillar hemorrhage.

The relationship between posttonsillectomy bleeding to hemogram and coagulation parameters

PURPOSE

Tonsillectomy is a common surgery performed for indications such as chronic tonsilitis, tonsil hypertrophy and obsructive sleep apnea. Although posttonsillectomy bleeding (PTB) is rare and can be controlled with simple interventions in many patients, it is one of the most feared complications of tonsillectomy surgery. In our study, we investigated the effects of changes in hemogram and coagulation values and seasonal effects on PTB.

METHODS

Pediatric and adult patients who underwent tonsillectomy with cold knife method between August 2020 and August 2023 in our clinic were retrospectively reviewed. Demographic data, hemogram and coagulation values of the patients in the control and study groups were recorded and the differences between the two groups in terms of these parameters were evaluated.

RESULTS

Our study included 991 patients aged 1-51 years. The rate of PTB was calculated as 2.82%. No patient with primary PTB was found. The duration of bleeding development was 7.03 days. Age, WBC and neutrophil values were statistically significantly higher in the study group. There were no significant differences between two groups in terms of gender, season and other hemogram and coagulation parameters.

CONCLUSIONS

Age, high WBC and neutrophil levels were determined as possible risk factors for PTB. Seasonal and gender distribution, aPTT and INR values were similar in the two groups. In order to prevent and predict bleeding, detailed infection investigation should be performed and the risk of bleeding should be considered to increase with increasing age.

Analysis of risk factors for post-tonsillectomy hemorrhage in adults

OBJECTIVES

To identify the risk factors for post-tonsillectomy hemorrhage (PTH) in adult patients (>19 years).

METHODS

275 adult patients who underwent tonsillectomy between 2009 and 2019 were retrospectively analyzed. Possible risk factors associated with PTH were investigated by univariate and multivariate logistic regression analyses.

RESULTS

PTH occurred in 39 of 275 patients (14.2%). Regarding underlying diseases, PTH occurred more frequently in focal infection of IgA nephropathy. Furthermore, bipolar electrocautery was the other risk factor for PTH on multivariate analysis.

CONCLUSION

Focal infection of IgA nephropathy and bipolar electrocautery were identified as the risk factors for PTH.

Investigation of Adult Post-Tonsillectomy Hemorrhage Rates and the Impact of NSAID Use

OBJECTIVES/HYPOTHESIS

Tonsillectomy is one of the most common ambulatory surgeries performed in the United States, yet the incidence of post-tonsillectomy hemorrhage (PTH) in adults remains unclear. In addition, any association between non-steroidal anti-inflammatory drugs (NSAIDs) and PTH in adults is currently unknown. The aim of this study is to examine the incidence and management of adult PTH at a single academic center and to assess for any association between NSAID use and PTH in adults.

STUDY DESIGN

Retrospective chart review.

METHODS

We conducted a retrospective chart review of adult tonsillectomies performed at our institution between January 1, 2012, and December 30, 2019. Demographics, past medical history, medications, NSAID use, surgical indication, bleeding events, and interventions were documented. The rate of PTH was calculated, logistic regression was performed to assess for any predictive factors, and odds ratios were calculated for NSAID use and PTH.

RESULTS

A total of 1,057 adult tonsillectomies were performed within the aforementioned time period. A total of 126 patients experienced 163 bleeding events for a postoperative hemorrhage rate of 11.9%. Most were controlled with bedside interventions, while 29 (23%) bled more than once. The hemorrhage rate for those who were not prescribed NSAIDs postoperatively (n = 625) was 11.7%, compared to 12.6% for those who did receive NSAIDs postoperatively (n = 432), which was not significantly different (adjusted odds ratio 1.01, 95% confidence interval 0.69-1.49; P = .95).

CONCLUSIONS

This retrospective cohort study of 1,057 adult patients found the incidence of PTH to be 11.9%. This study found no association between the use of NSAIDs and the rate of PTH, although a higher-powered study is needed.

Study of Patients’ Return to Surgery Post-Tonsillectomy and/or Adenoidectomy: A Relation Between Patient Age and Timing of Uncontrolled Bleeding

Background: Tonsillectomy and/or adenoidectomy (T/A) are common surgical procedures. Postoperative uncontrolled bleeding is a well-established complication; however, the relation between certain variables and uncontrolled bleeding are unclear. Methods: We explored the Pennsylvania Patient Safety Reporting System database for event reports that described a patient who had a T/A procedure and later returned to surgery to control bleeding. We analyzed the post-T/A bleeding events according to numerous variables, such as patient sex and age, timing of the bleed, procedure performed (i.e., tonsillectomy and/or adenoidectomy), and bleeding site. Results: We identified 219 event reports from 56 healthcare facilities over a four-year period. The study revealed that 78% of the patients were discharged and then returned to surgery to control bleeding. Patients ranged in age from 1–45 years and 53% were female. Among the 219 events, 41% were a primary bleed (0–1 postoperative days) and 59% were a secondary bleed (2–30 postoperative day). Additionally, 0–1 days and 6–7 days after operation were the periods when patients most frequently returned to surgery (range of 0–30 days). We expanded upon much of the previous research by exploring the relation between patient age and days postoperative return to surgery. We found that a majority of patients in age categories 1–10, 11–20, and 21–30 years had a secondary bleed; in contrast, a majority of patients age 31–45 had a primary bleed. Conclusion: Our findings indicate that the post-T/A timing of uncontrolled bleeding may vary systematically as a function of patient age; however, future research is needed to better understand this topic. We encourage readers to use our findings, along with findings from previous research, to inform their practice and strategies to mitigate risk of patient harm.

The efficacy of Tranexamic Acid Administration in Patients Undergoing Tonsillectomy: An Updated Meta-Analysis

OBJECTIVE

There is controversy regarding the efficacy and safety of tranexamic acid (TXA) in reducing tonsillectomy-related hemorrhage. We conducted a systematic review and meta-analysis to evaluate the prophylactic role of TXA in tonsillectomy.

METHODS

We searched 6 databases to identify studies that directly compare the effect of TXA versus controls in tonsillectomy patients. Standardized mean difference was applied to summate the findings across the studies. Dichotomous data were expressed as relative risk.

RESULTS

Ten studies representing a total of 111 898 patients were included. The pooled results showed a significant reduction of intraoperative blood loss by 39.02 ml (SMD = -1.05, 95% CI: -1.91 to -0.20, P = .016) and the rate of post-tonsillectomy hemorrhage (RR = 0.42, 95% CI: 0.28 to 0.65, P < .0001), with no significant difference in reduction of further intervention risk (RR = 0.78, 95% CI: 0.45 to 1.35, P = .373).

CONCLUSIONS

Overall, this study indicates that TXA may reduce blood loss and frequency of post-operative hemorrhage associated with tonsillectomy. Further large, high-quality clinical trials are still needed to explore TXA's effect on post-tonsillectomy hemorrhage and the safety of its use.

Risk factors of post-tonsillectomy hemorrhage in adults

OBJECTIVE

Tonsillectomy is an essential surgery and is conducted on both children and adults. However, the risk factors of post-tonsillectomy hemorrhage for adult patients remain unclear. In this study, we analyzed post-tonsillectomy hemorrhage in adult patients.

METHODS

We retrospectively analyzed 325 adult patients who underwent a tonsillectomy between 2014 and 2018 in our facilities.

RESULTS

The average age of this study's population was 31.7 ± 10.5 years (range: 19-70 years), and 250 (76.9%) patients were male. Overall, post-tonsillectomy hemorrhage occurred in 71 (21.8%) patients and 5 (1.5%) patients required a second surgery for hemostasis. Post-tonsillectomy hemorrhage often occurred on postoperative day zero or six. Using multiple logistic regression analysis, current smoking status (odds ratio 3.491; 95% confidence interval 1.813-6.723), male sex (odds ratio 3.924; 95% confidence interval 1.548-9.944), and perioperative non-steroidal anti-inflammatory drug administration (odds ratio 7.930; 95% confidence interval 1.004-62.64) were revealed as overall post-tonsillectomy hemorrhage risk factors. To analyze the hemorrhage period after tonsillectomy, we categorized the post-tonsillectomy hemorrhage patients into the primary (bleeding within postoperative day one) and secondary hemorrhage (bleeding on or after postoperative day two) groups. The current smoking status and older age were risk factors for primary hemorrhage and the current smoking status and sex (male) were risk factors for secondary hemorrhage.

CONCLUSIONS

In this study, smoking status, sex, and perioperative non-steroidal anti-inflammatory drug administration were the clinical risk factors for adult post-tonsillectomy hemorrhage. Thus, smoking cessation is, at least, mandatory for patients who receive tonsillectomy to avoid post-tonsillectomy hemorrhage.

Does Ibuprofen Increase Bleed Risk for Pediatric Tonsillectomy?

OBJECTIVE

To evaluate risk factors for pediatric posttonsillectomy hemorrhage (PTH) and the need for transfusion using a national database.

STUDY DESIGN

Retrospective cohort study.

SETTING

The study was conducted using the Pediatric Health Information System (PHIS) database.

METHODS

Children ≤18 years who underwent tonsillectomy with or without adenoidectomy (T±A) between 2004 and 2015 were included. We evaluated the risk of PTH requiring cauterization according to patient demographics, comorbidities, indication for surgery, medications, year of surgery, and geographic region.

RESULTS

Of the 551,137 PHIS patients who underwent T±A, 8735 patients (1.58%) experienced a PTH. The risk of PTH increased from 1.33% (95% confidence interval [CI]: 1.15%, 1.53%) in 2010 to 1.91% (95% CI: 1.64%, 2.24%) in 2015 (P < .001). Older age (≥12 vs <5 years old: adjusted odds ratio [aOR] 3.17; 95% CI: 2.86, 3.52), male sex (aOR 1.11; 95% CI: 1.05, 1.17), medical comorbidities (aOR 1.18; 95% CI: 1.08, 1.29), recurrent tonsillitis (aOR 1.15; 95% CI: 1.07, 1.24), and intensive care unit admission (aOR 1.74; 95% CI: 1.55, 1.95) were significantly associated with an increased risk of PTH. Use of ibuprofen (aOR 1.36; 95% CI: 1.22, 1.52), ketorolac (aOR 1.39; 95% CI: 1.14, 1.69), anticonvulsant (aOR 1.23; 95% CI: 1.03, 1.76), and antidepressants (aOR 1.35; 95% CI: 1.03, 1.76) were also associated with an increased risk of PTH. The need for blood transfusion was 2.1% (181/8735).

CONCLUSION

The incidence of PTH increased significantly between 2011 and 2015, and ibuprofen appears to be one contributing factor. Given the benefits of ibuprofen, it is unclear whether this increased risk warrants a change in practice.

Does suturing tonsil pillars post-tonsillectomy reduce postoperative hemorrhage?: A literature review

OBJECTIVE

Literature review comparing post-tonsillectomy hemorrhage in pediatric and adult patients with and without suturing tonsil pillars to investigate whether suturing tonsil pillars reduces the risk of post-tonsillectomy hemorrhage.

REVIEW METHODS

Online journal databases were searched using the key phrases "post tonsillectomy hemorrhage", "post tonsillectomy bleed", and "tonsil pillar suture". 10 published studies were found regarding tonsil pillar suturing, four directly related to postoperative bleeding and five focusing on postoperative pain reduction. There was one study that evaluated both pain and bleeding. The pain reduction studies were comprised of 225 patients while the postoperative bleeding studies included 3987 patients.

CONCLUSIONS

Suturing tonsil pillars after tonsillectomy may be beneficial after cold tonsillectomy.

IMPLICATIONS FOR PRACTICE

Post-operative bleeding is one of the most common complications that can result in increased patient distress and hospitalization. In this article, we provide a literature review of tonsil pillar suturing and post-tonsillectomy hemorrhage. Our study suggests suturing the tonsil pillars immediately post-tonsillectomy may reduce the risk of severe post-operative bleeding requiring return to the operating room for certain patients.

Predictors for hemorrhage following pediatric adenotonsillectomy

OBJECTIVE

To determine risk factors and trends for posttonsillectomy hemorrhage (PTH) following adenotonsillectomy (T&A) at a single children's tertiary referral hospital.

METHODS

Charts from all patients 2-12 years old undergoing T&A alone at a single children's hospital from January 1, 2010 through December 31, 2015 were reviewed. Data was collected on patient demographics, indication for procedure, time of year, academic affiliation of surgeon, surgical technique and method, post-operative pain medication prescribed,and readmission for PTH. Univariate chi-square analyses and logistic regression along with multivariable stepwise logistic regression were used to identify predictors of PTH. SPSS version 24 was used for statistical analyses with p < .05 indicating statistical significance.

RESULTS

There were 2565 children undergoing T&A during the study period. One hundred seventy-three (6.7%) patients were readmitted, of which 53 (30.6%) were due to PTH. Univariate analyses identified children at the highest age quartile of the study, 7.72-12.97 years old (odds ratio [OR] = 5.775, 95% confidence interval [CI] = 2.248-14.837, p < .001) and children with a BMI z-score of 2 or greater (OR = 3.391, 95% CI = 1.497-7.680, p = .003) were at increased risk for PTH. Multivariable analyses also identified both the highest age quartile and BMI z-score of 2 or greater to be a risk factor for PTH.

CONCLUSION

In children undergoing T&A, age greater than 7.72 years old and BMI z-score of 2 or greater are significant risk factors for PTH. Replication of these findings in a more highly powered trial is needed.

Practice patterns in the management of post-tonsillectomy hemorrhage: An American Society of Pediatric Otolaryngology survey

OBJECTIVES

To evaluate practice patterns amongst pediatric otolaryngologists in the management of post-tonsillectomy hemorrhage.

METHODS

A cross-sectional survey of the American Society of Pediatric Otolaryngology membership was administered electronically. The survey contained questions related to practice type, availability of resident and fellow call coverage, and management of different scenarios of post-tonsillectomy hemorrhage. Anonymous responses were collected and tabulated.

RESULTS

The response rate was 157/443 (35%). For patients presenting with a convincing history of post-tonsillectomy hemorrhage but no clot or bleeding on exam, the most common management was overnight observation (55%) or discharge home with close follow-up (29%). In patients presenting with tonsillar clot but no active bleeding, the most common management was operating room for control (50%), followed by observation (25%) and bedside topical treatment (13%). In the same scenario with a cooperative teenager, bedside topical treatment was most common (45%), followed by operating room for control (27%) and observation (16%). In patients presenting with active tonsillar bleeding, operating room for control was most common (83%) while few (6%) attempted bedside treatment. If the patient was a cooperative teenager, 38% attempted bedside treatment while 52% would still go to the operating room.

CONCLUSIONS

There is substantial variation in the management of post-tonsillectomy hemorrhage amongst the pediatric otolaryngologists. Further studies to determine outcomes associated with differing treatment strategies would be useful in establishing practice recommendations.

Tonsillectomy Bleed Rates across the CHEER Practice Research Network: Pursuing Guideline Adherence and Quality Improvement

OBJECTIVES

(1) Compare postoperative bleeding in the CHEER network (Creating Healthcare Excellence through Education and Research) among age groups, diagnoses, and practice types. (2) Report the incidence of bleeding by individual CHEER practice site based on practice guidelines.

STUDY DESIGN

Retrospective data collection database review of the CHEER network based on ICD-9 and CPT codes related to tonsillectomy patients.

SETTING

Multisite practice-based network.

SUBJECTS AND METHODS

A total of 8347 subjects underwent tonsillectomy as determined by procedure code within the retrospective data collection database, and 107 had postoperative hemorrhage. These subjects had demographic information and related diagnoses based on the CPT and ICD-9 codes collected. Postoperative ICD-9 and CPT codes were used to identify patients who also had postoperative bleed. Variables included age (<12 vs ≥12 years), diagnoses (infectious vs noninfectious), and practice type (community vs academic). Statistical analysis included multivariate logistic regression variables predictive of postoperative bleeding, with P < .05 considered significant.

RESULTS

Thirteen sites contributed data to the study (7 academic, 6 community). There was postoperative bleeding for an overall bleed rate of 1.3%. Patients ≥12 years old had a significantly increased bleed rate when compared with the younger group (odds ratio, 5.98; 95% confidence interval: 3.79-9.44; P < .0001). There was no significant difference in bleed rates when practices or diagnoses were compared.

CONCLUSION

A site descriptor database built to expedite clinical research can be used for practice assessment and quality improvement. These data were also useful to identify patient risk factors for posttonsillectomy bleed.

Hemostasis in Tonsillectomy

Tonsillectomy is a commonly performed procedure with an accepted risk of posttonsillectomy hemorrhage (PTH) approaching 5%, but catastrophic effects of hemorrhage are exceedingly rare. A variety of surgical techniques and hemostatic agents have been used to reduce the rate of hemorrhage, although none eliminate the risk. Numerous patient, surgical, and postoperative care factors have been studied for an association with PTH. The most consistent risk factors for PTH seem to be patient age and coagulopathies. Surgeon skill and surgical technique are most consistently associated with primary PTH.

Lower-pole intracapsular tonsillectomy in obstructive sleep apnea patients

CONCLUSION

Lower-pole intracapsular tonsillectomy (LPIT) is a valuable surgical technique capable of decreasing post-operative bleeding in obstructive sleep apnea (OSA) patients.

OBJECTIVE

This study performed LPIT to simultaneously reduce post-operative bleeding of lower pole and prevent recurrent tonsillitis of upper pole and compared its effects to extracapsular tonsillectomy (ET).

METHODS

ET was performed in the extracapsular plane, with complete monopolar dissection. In LPIT, the upper pole of palatine tonsil was removed by electrocautery with the extracapsular plane, followed by removal of the lower-pole by plasma ablation with the intracapsular plane. Post-operative bleeding incidence, bleeding site, and degree of pain were compared between the two groups.

RESULTS

Three hundred and forty-seven patients diagnosed of OSA with polysomnography were enrolled. ET was performed in 152 patients and LPIT in 195 patients. There were no significant differences in post-operative pain between the two groups. The LPIT group showed significantly lower total bleeding incidence than the ET group (4.1% vs 9.2%; p = .05). In particular, lower-pole bleeding incidence was lower in the LPIT group than the ET group (1.0% vs 5.3%; p = .02).

Postoperative Bleeding and Associated Utilization following Tonsillectomy in Children

Objective To assess posttonsillectomy hemorrhage (PTH), associated nonoperative readmissions/revisits, and reoperations in children. Data Sources MEDLINE, EMBASE, and the Cochrane Library. Review Methods Two investigators independently screened studies against predetermined criteria and extracted key data. Investigators independently assessed study risk of bias and the strength of the evidence of the body of literature. We calculated unadjusted pooled estimates of PTH frequency and conducted a Bayesian meta-analysis to estimate frequency of primary and secondary PTH and PTH-associated reoperation and revisits/readmissions by partial and total tonsillectomy and surgical approach. Results In meta-analysis, the frequency of primary and secondary PTH associated with total and partial tonsillectomy was <4% for any technique and with overlapping confidence bounds. Pooled frequencies of PTH were also <5% overall (4.2% for total tonsillectomy, 1.5% for partial tonsillectomy) in comparative studies. Fewer PTH episodes occurred with tonsillectomy for obstructive sleep-disordered breathing than for throat infection. In meta-analysis, frequency of PTH-associated nonoperative revisits/readmission or reoperation ranged from 0.2% to 5.7% for total tonsillectomy and from 0.1% to 3.7% for partial tonsillectomy. At least 4 deaths were reported in case series including 1,778,342 children. Conclusions PTH occurred in roughly 4% of tonsillectomies in studies included in this review. Although studies typically did not report bleeding severity or amount, relatively few episodes of PTH necessitated reoperation for hemostasis. Nonetheless, tonsillectomy is not without risk of harm. Frequency of PTH across techniques was similar; thus, we cannot conclude that a given technique is superior.

Is celecoxib a useful adjunct in the treatment of post-tonsillectomy pain in the adult population? A randomised, double-blind, placebo-controlled study

OBJECTIVE

To evaluate the efficacy and safety of celecoxib for pain management in post-tonsillectomy adult patients.

DESIGN

A randomised, double-blind, placebo-controlled, phase 3 clinical trial was conducted in an adult population (aged 18-55 years), with a parallel group design using an allocation ratio of 1:1.

METHODS

Eighty patients underwent elective tonsillectomy or adenotonsillectomy, operated on by one surgeon. They were discharged home with randomly assigned celecoxib or placebo, together with regular post-tonsillectomy medications (paracetamol and Endone). Pain scores were measured from post-operative days 1 to 10. All patients were assessed on post-operative days 5, 12 and 28.

RESULTS

There were no statistically significant differences in the daily or overall pain scores, the total intake of Endone, or the time taken to achieve freedom from pain after tonsillectomy between the study arms (n = 40 each arm). The celecoxib-treated group experienced significantly more vomiting (celecoxib vs placebo p < 0.001 (Mann-Whitney test), confidence interval = 0.57 to 0.76).

CONCLUSION

Celecoxib usage was associated with significantly more vomiting and did not reduce narcotic analgesia requirement post-tonsillectomy.

Risk factors for pediatric post-tonsillectomy hemorrhage

OBJECTIVES

To determine pre-operative risk factors for post-tonsillectomy secondary hemorrhage in children, and quantify the magnitude of their risk.

MATERIALS AND METHODS

Retrospective case-control study of all pediatric tonsillectomy patients experiencing post-operative bleeding from 2005 to 2010 in a community practice consisting of three fellowship-trained pediatric otolaryngologists were identified. The 91 cases were matched with 151 controls that underwent tonsillectomy by the same surgeon on the same day as each identified case. All charts were reviewed, and 41 pre-operative variables were extracted and statistically analyzed with contingency and regression analysis to calculate significance and odds ratios.

RESULTS

Three significant predictors of post-operative bleeding were identified. Performing a tonsillectomy on a child with recurrent tonsillitis (vs. other indications) increased the risk of post-operative hemorrhage by 4.5 times (p<0.0001, 95% confidence intervals 2.41-8.38). Performing a tonsillectomy on a child with attention deficit hyperactivity disorder (ADHD) increased the risk by 8.7 times (p=0.029, 95%CI 1.4-53.6). Older children were more predisposed to post-operative bleeding. For every increase in age by one year, the hemorrhage risk increased by 1.1 times (p=0.0025, 95%CI 1.032-1.162). Children 11 years of age and older had double the risk of bleeding compared to younger children (odds ratio 1.98, p=0.0381, 95%CI 1.04-3.79). None of the remaining 38 variables showed significant differences between cases and controls.

CONCLUSIONS

The risk of post-tonsillectomy hemorrhage is significantly increased in older children and those with recurrent tonsillitis and ADHD.

Efficacy of sucralfate for the treatment of post-tonsillectomy symptoms

Pain after tonsillectomy remains the main issue of postoperative morbidity and the search for an effective post-tonsillectomy analgesic is of increasing relevance. The aim of this study was to evaluate the effectiveness of topical sucralfate during an early post-tonsillectomy period. Fifty patients of both genders from 6 to 58 years submitted to tonsillectomy or adenotonsillectomy were randomly included into either a sucralfate treatment group (N = 25) or into a control group (N = 25). Patients of the sucralfate group received topical sucralfate four times a day for 7 days. No topical treatment was applied to patients of the control group. A systemic analgesic was standardized. Post-tonsillectomy symptoms, including throat pain, odynophagia and otalgia, were evaluated during the period of seven postoperative days. Secondary outcomes were analgesic use, well being in general, return to regular daily activities, secondary hemorrhage and side effects of sucralfate. This study revealed that during the period of the second to seventh postoperative days average throat pain scores of the sucralfate using patients were significantly lower than those of the control group patients (p < 0.05); the same could be applied to odynophagia scores during the period of all seven postoperative days (p < 0.01) and otalgia scores from the 4th postoperative day (p < 0.05). The sucralfate group patients also had a significantly smaller need for analgesics, better scores of well being in general and early return to regular daily activities with no side effects of the treatment. Topical sucralfate could be recommended for the everyday clinical practice as a safe, adjuvant medicine of treatment during the period of the first post-tonsillectomy week.
