Postoperative tonsillectomy bleeding complications in children: A comparison of three surgical techniques

Postoperative Bleeding in Children With Tonsillectomy: A Retrospective Cohort

BACKGROUND

It is necessary to evaluate the risk factors of secondary bleeding after tonsillectomy in children, to provide reference for clinical children management and care.

METHODS

Children who underwent tonsillectomy from January 1, 2018, to December 31, 2022, in our hospital were retrospectively included. The characteristics of children with and without secondary bleeding were analyzed.

RESULTS

A total of 1068 children undergoing tonsillectomy were included, and the incidence of secondary bleeding children undergoing tonsillectomy was 4.87%. Age ≥ 9 years old (odds ratio [OR] = 2.609, 95% confidence interval [CI] = 2.112-3.437), type of surgery (OR = 1.764, 95% CI = 1.148-2.291), and degree of tonsil embedding (OR = 2.116, 95% CI = 1.805-2.644) were the risk factors of secondary bleeding after tonsillectomy in children (all P < .05).

CONCLUSION

Medical staff should proactively monitor and address the identified risk factors by implementing timely warning systems and preventive strategies to reduce the postoperative bleeding following tonsillectomy.

PlasmaBlade versus Electrocautery for Deep Inferior Epigastric Perforator Flap Harvesting in Autologous Breast Reconstruction: A Comparative Clinical Outcome Study

(1) Background: DIEP-based breast reconstruction necessitates wide undermining at the abdominal donor site, creating large wound areas. Flap harvesting is usually conducted using electrosurgical dissection devices. This study sought to compare the clinical outcomes in patients after using the PEAK PlasmaBlade (PPB) versus monopolar electrocautery (MPE). (2) Methods: This retrospective cohort study included 128 patients with DIEP-based breast reconstruction. Patient characteristics and information on the postoperative course were collected and a comparative evaluation was conducted. (3) Results: The MPE group exhibited significantly (p* = 0.0324) higher abdominal drainage volume (351.11 ± 185.96 mL) compared to the PPB group (279.38 ± 183.38 mL). A subgroup analysis demonstrated that PPB significantly reduced postoperative wound fluid in patients with BMI > 30 kg/m2 (p* = 0.0284), without prior neoadjuvant chemotherapy (p** = 0.0041), and among non-smokers (p = 0.0046). Furthermore, postoperative pain was significantly (p**** < 0.0001) lower in the PPB cohort. (4) Conclusions: This study confirms the non-inferiority of the PEAK PlasmaBlade to conventional electrocautery for abdominal flap harvesting. The PPB demonstrated advantages, notably reduced drainage volume and lower postoperative pain levels. Recognizing patient subsets that benefit more from the PPB highlights the importance of personalized device selection based on patient characteristics.

Impact of Ketorolac on Reoperation for Hemorrhage After Pediatric Tonsillectomy: A Single-Center Retrospective Propensity-Matched Study

OBJECTIVE

To determine if perioperative ketorolac is associated with an increased rate of reoperation for hemorrhage after pediatric tonsillectomy at 30 days and 48 hours.

STUDY DESIGN

Single-center retrospective propensity-matched study.

SETTING

Quaternary pediatric hospital and ambulatory surgery center.

METHODS

Patients less than 18 years old undergoing tonsillectomy or adenotonsillectomy between January 1, 2015 and October 1, 2020 were included. Hemorrhage rates between exposed (K+) and unexposed (K-) patients were calculated for the total cohort and a 1:1 propensity-matched cohort. Additional analyses included: multivariable logistic regression, subgroup analysis of ASA 1 and 2 patients, subgroup analysis comparing children with teenagers.

RESULTS

There were 5873 patients (42.1% K+) in the full cohort and 4694 patients in the propensity-matched cohort. Reoperation for hemorrhage within 30 days occurred in 1.9% of K+ patients and 1.6% of K- patients (P = 0.455) in the full cohort and 1.9% of K+ patients and 1.7% of K- patients (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.72-1.69, P = 0.662) in the propensity-matched cohort. Reoperation within 48 hours occurred in 0.65% of K+ patients and 0.53% of K- patients (P = 0.679) in the full cohort and 0.68% of K+ patients and 0.51% of K- patients (OR 1.33, 95% CI 0.63-2.81, P = 0.451) in the propensity-matched cohort. There was no association between perioperative ketorolac administration and reoperation for hemorrhage in any of the other analyses.

CONCLUSION

Ketorolac at end of surgery should be considered as part of the nonopioid analgesic regimen for pediatric tonsillectomy.

Incidence and predictors of readmission following tonsillectomy in pediatric population

BACKGROUND

Tonsillectomy is one of the most common surgical procedures performed in the pediatric population. This study aims to estimate the incidence rate of readmission post tonsillectomy in pediatrics and identify the causes and predictors contributing to the readmission post-surgery.

METHODS

A retrospective cohort study included 1280 pediatric patients (18 years or younger) who underwent tonsillectomy at a tertiary hospital in 2019 and 2020. The study sample was divided into two groups based on readmission and were compared using the appropriate statistical tests. Significant variables (p-value≤0.05) were included in the logistic regression model to determine the predictors of readmission following tonsillectomy in these patients.

RESULTS

The readmission rate following tonsillectomy was 6.3 % (95 % confidence interval 5.1-7.9). The causes of readmission included poor oral intake followed by bleeding and vomiting, 55.6 %,49.4 %, and 13.6 %, respectively. In the multivariable logistic regression model, the only significant predictor of post-tonsillectomy readmission was the use of a single postoperative analgesia (OR: 57.27, P = 0.000).

CONCLUSION

The readmission rate following tonsillectomy in this study was relatively high. The most common causes contributing to readmission post tonsillectomy were poor oral intake and hemorrhage. The study also revealed a significant association between the utilization of single postoperative analgesia and an increased likelihood of readmission.

The Impact of Surgical Indication on Posttonsillectomy Hemorrhage: A Systematic Review and Meta-Analysis

OBJECTIVE

To investigate the impact of the surgical indication on posttonsillectomy bleed rates.

DATA SOURCES

PubMed, Scopus, CINAHL.

REVIEW METHODS

A systematic review was performed searching for articles published from the date of inception to July 6, 2022. English language articles describing posttonsillectomy hemorrhage rates in pediatric patients (age ≤ 18) stratified by indication were selected for inclusion. A meta-analysis of proportions with comparison (Δ) of weighted proportions was conducted. All studies were assessed for risk of bias.

RESULTS

A total of 72 articles with 173,970 patients were selected for inclusion. The most common indications were chronic/recurrent tonsillitis (CT/RT), obstructive sleep apnea/sleep-disordered breathing (OSA/SDB), and adenotonsillar hypertrophy (ATH). Posttonsillectomy hemorrhage rates for CT/RT, OSA/SDB, and ATH were 3.57%, 3.69%, and 2.72%, respectively. Patients operated on for a combination of CT/RT and OSA/SDB had a bleed rate of 5.99% which was significantly higher than those operated on for CT/RT alone (Δ2.42%, p = .0006), OSA/SDB alone (Δ2.30%, p = .0016), and ATH alone (Δ3.27%, p < .0001). Additionally, those operated on for a combination of ATH and CT/RT had a hemorrhage rate of 6.93%, significantly higher than those operated on for CT/RT alone (Δ3.36%, p = .0003), OSA/SDB alone (Δ3.01%, p = .0014), and ATH alone (Δ3.98%, p < .0001).

CONCLUSION

Patients operated on for multiple indications had significantly higher rates of posttonsillectomy hemorrhage than those operated on for a single surgical indication. Better documentation of patients with multiple indications would help further characterize the magnitude of the compounding effect described here.

A comparison of coblation and modified monopolar tonsillectomy in adults

OBJECTIVE

To compare the intraoperative records and postoperative clinical outcomes of adults who underwent coblation and modified monopolar tonsillectomy tonsillectomies.

MATERIALS AND METHODS

Adult patients with tonsillectomy were randomly divided into the coblation and modified monopolar tonsillectomy groups. The estimated blood loss, postoperative pain score, operation time, post-tonsillectomy hemorrhage (PTH), and cost of disposable equipment were compared.

RESULTS

Pain intensity in the coblation and monopolar groups was similar on postoperative days 3 and 7. However, the mean maximum pain score in the monopolar group was significantly higher compared to the coblation group on postoperative days 1 (P < 0.01) and 2 (P < 0.05).Secondary PTH occurred in 7.1% (23/326) of patients in the coblation group and 2.8% (9/327) of patients in the monopolar group (P < 0.05).

CONCLUSION

Although pain was significantly increased on postoperative days 1 and 2 in the modified monopolar tonsillectomy group, the operation time, secondary PTH, and medical costs were significantly decreased compared to the coblation technique group.

Comparing nationally reported adverse events associated with coblation vs. PlasmaBlade for tonsillectomy

OBJECTIVE(S)

Coblation, or radiofrequency ablation, and pulsed-electron avalanche knife (PEAK) plasmablade are newer approaches for tonsillectomy that reduce exposure to thermal heat. This study aims to describe and compare adverse events related to these devices for tonsillectomy.

STUDY DESIGN

Retrospective cross-sectional study.

SETTING

The US Food and Drug Administration's Manufacture and User Facility Device Experience (MAUDE) database.

METHODS

The MAUDE database was queried for reports involving coblation devices and the PEAK plasmablade from 2011 to 2021. Data were extracted from reports pertaining to tonsillectomy with and without adenoidectomy.

RESULTS

There were 331 reported adverse events for coblation and 207 for the plasmablade. For coblation, 53 (16.0 %) of these involved patients and 278 (84.0 %) were device malfunctions. Similarly for the plasmablade, 22 (10.6 %) involved patients and 185 (89.4 %) were device malfunctions. The most frequent patient-related adverse event was burn injury, which was significantly more common with the plasmablade compared to coblation (77.3 % vs. 50.9 %, respectively, p = 0.042). For both the coblator and plasmablade, the most common device malfunction was intraoperative tip or wire damage (16.9 % vs. 27.0 %, respectively, p = 0.010). The Plasmablade tip caught fire in five reports (2.7 %) with one causing burn injury.

CONCLUSIONS

While coblation devices and the plasmablade have demonstrated utility in tonsillectomy with or without adenoidectomy, they are associated with adverse events. Plasmablade use may require greater caution for intraoperative fires and patient burn injuries compared to coblation use. Interventions to improve physician comfort with these devices may help reduce adverse events and inform preoperative discussions with patients.

Comparison of three common tonsil surgery techniques: cold steel with hot hemostasis, monopolar and bipolar diathermy

PURPOSE

To analyze the risk of postoperative hemorrhage in tonsil surgery with different surgical methods, instruments, indications, and age groups. Monopolar diathermy compared to bipolar diathermy was of particular interest.

METHODS

The data from tonsil surgery patients were retrospectively collected between 2012 and 2018 in the Hospital District of Southwest Finland. The surgical method, instruments, indication, sex and age and their association with a postoperative hemorrhage were analyzed.

RESULTS

A total of 4434 patients were included. The postoperative hemorrhage rate for tonsillectomy was 6.3% and for tonsillotomy 2.2%. The most frequently used surgical instruments were monopolar diathermy (58.4%) cold steel with hot hemostasis (25.1%) and bipolar diathermy (6.4%) with the overall postoperative hemorrhage rates 6.1%, 5.9% and 8.1%, respectively. In tonsillectomy patients, the risk for a secondary hemorrhage was higher with bipolar diathermy compared to both monopolar diathermy (p = 0.039) and the cold steel with hot hemostasis technique (p = 0.029). However, between the monopolar and the cold steel with hot hemostasis groups, the difference was statistically non-significant (p = 0.646). Patients aged > 15 years had 2.6 times higher risk for postoperative hemorrhage. The risk of a secondary hemorrhage increased with tonsillitis as the indication, primary hemorrhage, tonsillectomy or tonsillotomy without adenoidectomy, and male sex in patients aged ≤ 15 years.

CONCLUSION

Bipolar diathermy increased the risk for secondary bleedings compared to both monopolar diathermy and the cold steel with hot hemostasis technique in tonsillectomy patients. Monopolar diathermy did not significantly differ from the cold steel with hot hemostasis group regarding the bleeding rates.

A novel classification and grading scale of palatine tonsil anatomy in children

PURPOSE

The influence of tonsil anatomical differences on post-tonsillectomy hemorrhage and pain has not been studied yet. This study aimed to establish a classification and grading scale of palatine tonsil anatomy, not size, for personalized post-tonsillectomy care.

METHODS

Between August 2020 and August 2021, 337 children who underwent extracapsular tonsillectomy were recruited. The images of tonsil anatomy during the surgery were recorded and then classified and graded. Postoperative hemorrhage was recorded, and the degree of pain was measured using a visual analog scale (VAS). The primary outcomes were the associations between postoperative hemorrhage, pain, and the classification and grade of tonsil anatomy, analyzed by univariable and multivariable analyses.

RESULTS

186 of the 337 patients (55.2%) were male and 151 (44.8%) were female; the mean age was 5.59 years. The overall postoperative hemorrhage rate was 4.1%. The mean postoperative VAS score was 4.96. By univariable analysis with logistic regression model, significant associations were found between postoperative hemorrhage and the grade 2 and grade 3 tonsillar lower pole, and grade 3 tonsillar bed. Multivariable analysis with binary logistic regression model also revealed significant associations between postoperative hemorrhage and the grade 2 and grade 3 lower pole (OR: 8.23, 95% CI 1.01-67.37, P = 0.049; OR: 23.86, 95% CI 2.22-56.47, P = 0.009, respectively) and grade 3 tonsillar bed (OR: 14.25, 95% CI 1.46-18.75, P = 0.022). Linear regression analysis showed the associations between postoperative pain and grade 2 and grade 3 lower pole (β: 0.88, 95% CI 0.31-1.32, P = 0.002; β: 1.56, 95% CI 1.29-3.29, P = 0.001, respectively) and grade 3 anterior surface (β: 0.85, 95% CI 0.30-3.07, P = 0.004). Age and upper pole were not associated with the postoperative hemorrhage and pain neither.

CONCLUSION

In the present study, we established a novel classification and 3-grade scale of palatine tonsil anatomy, based on upper pole, anterior surface, lower pole, and tonsillar bed. Furthermore, we revealed for the first time that some anatomical characteristics of tonsils were associated with post-tonsillectomy complications.

Medical Gas Plasma—A Potent ROS-Generating Technology for Managing Intraoperative Bleeding Complications

Cold medical gas plasmas are under pre-clinical investigation concerning their hemostatic activity and could be applied for intra-operative bleeding control in the future. The technological leap innovation was their generation at body temperature, thereby causing no thermal harm to the tissue and ensuring tissue integrity. This directly contrasts with current techniques such as electrocautery, which induces hemostasis by carbonizing the tissue using a heated electrode. However, the necrotized tissue is prone to fall, raising the risk of post-operative complications such as secondary bleedings or infection. In recent years, various studies have reported on the ability of medical gas plasmas to induce blood coagulation, including several suggestions concerning their mode of action. As non-invasive and gentle hemostatic agents, medical gas plasmas could be particularly eligible for vulnerable tissues, e.g., colorectal surgery and neurosurgery. Further, their usage could be beneficial regarding the prevention of post-operative bleedings due to the absence or sloughing of eschar. However, no clinical trials or individual healing attempts for medical gas plasmas have been reported to pave the way for clinical approvement until now, despite promising results in experimental animal models. In this light, the present mini-review aims to emphasize the potential of medical gas plasmas to serve as a hemostatic agent in clinical procedures. Providing a detailed overview of the current state of knowledge, feasible application fields are discussed, and possible obstacles are addressed.

A prospective, randomized, single‐blind study comparing coblation and monopolar extracapsular tonsillectomy

Objective

The aim of this study was to compare intraoperative blood loss, postoperative pain, post‐tonsillectomy hemorrhage (PTH), and medical costs associated with extracapsular tonsillectomy between coblation and monopolar electrocautery in children.

Materials and methods

This study included 293 patients aged 6–15 years planned to undergo extracapsular tonsillectomy. Data on estimated blood loss, postoperative pain score, operation time, PTH, and the cost of disposable equipment were collected.

Results

Coblation extracapsular tonsillectomy was associated with significantly lower mean pain scores than monopolar technique on postoperative days 1 (p <.001) and 2 (p = 0.02). However, the pain score was similar between the groups at all other time points. The monopolar group had a significantly shorter operation time compared to the coblation group (11.09 ± 7.53 vs. 17.12 ± 4.29 min, p <.001). Intraoperative estimated blood loss was not significantly different between the groups (p = .43).The cost of extracapsular tonsillectomy was significantly lower in the monopolar compared to the coblation group (US$ 28.18 vs. US$ 430.48, p <.001). PTH occurred in 17 patients (5.80%) and required a second surgery. Secondary PTH occurred in 6.16% (9/146) and 0.68% (1/147) of patients in the coblation and monopolar groups, respectively (p <.001). The PTH was significantly higher in the tonsillitis compared to in the tonsillar hypertrophy (12.37% vs. 2.55%, p = .002), However, the difference of PTH was not significant among mean pain scores subgroups. Of the 17 patients with PTH, the lower pole, middle portion, and upper pole were involved in 15 (88.24%), 2 (11.76%), and 0 cases, respectively.

Conclusions

Coblation and novel monopolar electrocautery extracapsular tonsillectomy are associated with similar postoperative pain scores except on postoperative days 1 and 2. However, monopolar technique offers significant advantages over coblation method with less operative time, decreased secondary PTH, and cost.

Early Pacemaker Implantation after Transcatheter Aortic Valve Replacement: Impact of PlasmaBlade™ for Prevention of Device-Associated Bleeding Complications

Background and Objectives: Permanent pacemaker implantation (PPI) is frequently required following transcatheter aortic valve replacement (TAVR). Dual antiplatelet therapy (DAPT) or oral anticoagulation therapy (OAK) is often necessary in these patients since they are at higher risk of thromboembolic events due to TAVR implantation, high incidence of coronary artery diseases (CAD) with the necessity of coronary intervention, and high rate of atrial fibrillation with the need of stroke prevention. We sought to evaluate the safety, efficiency, and clinical outcomes of early PPI following TAVR using the PlasmaBlade™ (Medtronic Inc., Minneapolis, MN, USA) pulsed electron avalanche knife (PEAK) for bleeding control in patients under DAPT or OAK. Materials and Methods: This retrospective single-center study included patients who underwent PPI after transfemoral TAVR (TF) at our center between December 2015 and May 2020. All PPI were performed using the PlasmaBlade™ Device. Results: The overall PPI rate was 14.1% (83 of 587 patients; 82.5 ± 4.6 years; 45.8% male). The PPI procedures were used to treat high-grade atrioventricular block (81.9%), severe sinus node dysfunction (13.3%), and alternating bundle branch block (4.8%). At the time of the procedure, 35 (42.2%) patients received DAPT, and 48 (57.8%) patients received OAK (50% with vitamin K antagonist (VKA) and 50% with novel oral anticoagulants (NOAK)). One device-pocket hematoma treated conservatively occurred in a patient (1.2%) receiving NOAK. Two re-operations were necessary in patients due to immediate lead dislocation (2.4%). Conclusions: The results of this study illustrate that the use of PlasmaBlade™ for PPI in patients after a TAVR who require antithrombotic treatment is feasible and might result into lower rates of severe bleeding complications compared to rates reported in the literature. Use of the PlasmaBlade device may be considered in this specific group of patients because of their high risk of bleeding.

Comparative healing of swine skin following incisions with different surgical devices

Background

Electrosurgical technology is widely used in surgical dissection and hemostasis, but the generated heat creates thermal injury to adjacent tissues and delays wound healing. The plasma blade (PB) applies pulsed radiofrequency (RF) to generate electrical plasma along the edge of a thin, flat, insulated electrode, minimizing collateral tissue damage. This study aimed to evaluate wound healing in swine skin following incision with a new surgical system that applies low-temperature plasma (NTS-100), a foreign PB, conventional electrosurgery (ES), and a scalpel blade.

Methods

In vitro porcine skin and an in vivo porcine skin model were used in this study. Full-thickness skin incisions 3 cm in length were made on the dorsum of each animal for each of the 5 surgical procedures at 0, 21, 28, 35, and 42 days. The timing of the surgical procedures allowed for wound-healing data points at 1, 2, 3, and 6 weeks accordingly. Local operating temperature and blood loss were quantified. Wounds were harvested at designated time points, tested for wound tensile strength, and examined histologically for scar formation and tissue damage.

Results

Local operating temperature was reduced significantly with NTS-100 (cut mode 83.12±23.55 °C; coagulation mode 90.07±10.6 °C) compared with PB (cut mode 94.46±11.48 °C; coagulation mode 100.23±6.58 °C, P<0.05) and ES (cut mode 208.99±34.33 °C, P<0.01; coagulation mode 233.37±28.69 °C, P<0.01) in vitro. Acute thermal damage from NTS-100 was significantly less than ES incisions (cut mode: 247.345±42.274 versus 495.295±103.525 µm, P<0.01; coagulation mode: 351.419±127.948 versus 584.516±31.708 µm, P<0.05). Bleeding, histological scoring of injury, and wound strength were equivalent for the NTS-100 and PB incisions.

Conclusions

The local operating temperature of NTS-100 was lower than PB, and NTS-100 had similarly reliable safety and efficacy.

Comparison of Post-Tonsillectomy Hemorrhage between Monopolar and Plasma Blade Techniques

The plasma blade is an innovative device that was recently introduced for performing tonsillectomy. While one of the benefits of the plasma blade is limited thermal damage, the effects of plasma blades on postoperative hemorrhage have not been thoroughly investigated. Patients who underwent tonsillectomy in our institution between January 2013 and September 2018 were retrospectively enrolled in the study. A total of 1214 patients were enrolled in the study, with 759 participants who underwent monopolar tonsillectomy and 455 participants who underwent plasma blade tonsillectomy. In total, 14 bleeding events occurred in the monopolar group, and 10 events occurred in the plasma blade group. The odds ratio for postoperative bleeding in the plasma blade group was 1.20 (95% CI 0.52 to 2.72). After adjusting for potential confounders, the adjusted odds ratio was 1.34 (95% CI 0.58 to 3.07). In conclusion, there is no significant difference in post-tonsillectomy hemorrhage rates between the traditional monopolar technique and plasma blade technique. Plasma blade tonsillectomy can be considered as safe as traditional monopolar tonsillectomy.

Primary and secondary postoperative hemorrhage in pediatric tonsillectomy

BACKGROUND

Tonsillectomy is the most common procedure for treatment of pediatric recurrent acute tonsillitis and tonsillar enlargement that contributes to obstructive sleep apnea hypopnea syndrome. Postoperative hemorrhage of tonsillectomy is a life-threatening complication.

AIM

To identify the risk factors that may contribute to primary and secondary post-operative hemorrhage in pediatric tonsillectomy.

METHODS

The clinical data from 5015 children, 3443 males and 1572 females, aged 1.92-17.08 years, with recurrent tonsillitis and/or tonsil hypertrophy who underwent tonsillectomy in our hospital from January 2009 to December 2018 were retrospectively collected. The variables including sex, age, time of onset, diagnosis, method of tonsillectomy, experience of surgeon, time when the surgery started and monthly average air temperature were abstracted. The patients with postoperative hemorrhage were classified into two groups, the primary bleeding group and the secondary bleeding group, and their characteristics were compared with those of the nonbleeding group separately. Statistical analysis was performed by chi-square test with SPSS 20.

RESULTS

Ninety-two patients had post-tonsillectomy hemorrhage, and the incidence rate of post-tonsillectomy hemorrhage was 1.83%. The mean age was 5.75 years. Cases of primary hemorrhage accounted for approximately 33.70% (31/92), and cases of secondary hemorrhage occurred in 66.30% (61/92). The rate of reoperation for bleeding was 0.92%, and the rate of rehospitalization for bleeding was 0.88% in all patients. Multiple hemostasis surgery was performed in 6.52% (3/46) of patients. The method of tonsillectomy (coblation tonsillectomy) and experience of the surgeon (junior surgeon with less than 5 years of experience) were significantly associated with primary hemorrhage (χ² = 5.830, P = 0.016, χ²= 6.621, P = 0.010, respectively). Age (over 6 years old) and time of onset (more than a 1-year history) were significantly associated with secondary hemorrhage (χ²= 15.242, P = 0.000, χ²=4.293, P = 0.038, respectively). There was no significant difference in sex, diagnosis, time when the surgery started or monthly average air temperature. There was a significant difference in the intervention measures between the primary bleeding group and the secondary bleeding group (χ²= 10.947, P = 0.001). The lower pole and middle portion were the common bleeding sites, followed by the upper pole and palatoglossal arch.

CONCLUSION

The incidence rate of post-tonsillectomy hemorrhage is low. Coblation tonsillectomy and less than 5 years’ experience of surgeon contribute to the tendency for primary hemorrhage. Age and time of onset are responsible for secondary hemorrhage.

Using Lean to Improve Patient Safety and Resource Utilization After Pediatric Adenotonsillectomy

OBJECTIVE

The objective of this quality improvement project was to decrease the rate of nonemergent use of emergency department (ED) resources in children undergoing adenotonsillectomy by 50% and/or reach a future state of 5% or less overall ED visits among all postoperative patients within 1 year. A secondary objective was to standardize the preoperative, intraoperative, and postoperative management of these patients.

METHODS

The study was a quality improvement project using Lean. The target population was children younger than 18 years undergoing tonsillectomy with or without adenoidectomy. A retrospective review of adenotonsillectomy was performed for a 12-month period. Lean tools including A3 Thinking, Ishikawa "fishbone" diagram, and value stream mapping were used to analyze the problem and identify interventions. Postintervention data were collected for a 10-month period.

RESULTS

Compared with the baseline period, the ED visit rate after adenotonsillectomy decreased from 36.2% to 15.5% (P = 0.0095). The rate of ED visits for nonbleeding complaints decreased from 30.4% to 12.1% (P = 0.01748). There was no significant change in rate of ED visits for bleeding (decreased from 5.8% to 3.5% [P = 0.6873]). There was no significant change in the use of intraoperative dexamethasone and acetaminophen.

CONCLUSIONS

Postadenotonsillectomy patients often use emergency resources better reserved for other patients. Addressing this problem with Lean principles significantly decreased postoperative ED visit rates by more than 50%.

IMPLICATIONS FOR PRACTICE

To our knowledge, this is the first reported use of Lean principles to decrease utilization of emergency resources in the postoperative period. Lean can be applied to other processes in our field to eliminate waste and add value to improve patient outcomes.

Endovascular Embolization for Control of Post-Tonsillectomy Hemorrhage

Post-operative hemorrhage is a potentially life-threatening complication of tonsillectomy. While standard surgical maneuvers including the use of electrocautery, application of topical hemostatic agents, direct pressure, and suturing of the tonsillar pillars have traditionally been used for the treatment of severe bleeding, endovascular approaches are an important adjunct when other techniques are unsuccessful. Here, we describe the case of a 10-year-old female who presented with severe bleeding four days after tonsillectomy and adenoidectomy for chronic tonsillitis. She was taken emergently to the operating room where pulsatile bleeding was noted from the right inferior tonsillar pole. Hemostasis could not be achieved using electrocautery despite multiple attempts. The patient was taken for emergent angiography, which demonstrated an irregularity of the right tonsillar artery consistent with arterial vasospasm, and which corresponded to the intraoral site of bleeding localized by the surgeon. Coil embolization of the tonsillar artery was successfully performed, and the patient experienced no further bleeding. We conclude that endovascular embolization of branches of the external carotid artery is an effective treatment for severe post-tonsillectomy hemorrhage in children and should be considered when attempts at surgical control are ineffective. This procedure requires exceptional collaboration between the surgical, radiology, and anesthesia teams.

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.

Is Postextracapsular Tonsillectomy Bleeding More Common on the Side of the Surgeon's Nondominant Hand?

OBJECTIVES

To determine the difference in bleeding when extracapsular tonsillectomy with electrocautery is performed on the dominant and nondominant side of the surgeon's hands.

STUDY DESIGN

Retrospective cohort study.

SETTING

Academic university hospital.

METHODS

Medical record data of patients who were admitted with posttonsillectomy bleeding from January 1, 2000, to July 31, 2017, were reviewed. Included were age, sex, surgical indication, side of posttonsillectomy bleeding, and time of bleeding. Information on the surgeon's dominant hand was also collected. All patients underwent total extracapsular resection with electrocautery.

RESULTS

Of 280 patients, 186 met the inclusion criteria, 116 (62.3%) males and 70 (37.7%) females. Ages ranged from 2 to 74 years (mean ± SD, 17 ± 13 years; median, 13 years). In 136 cases (73.1%), bleeding was on the side of the surgeon's nondominant hand (P < .0001). In 50 (26.9%) cases, bleeding was on the side of the surgeon's dominant hand. The odds ratio of bleeding on the side of the surgeon's nondominant hand compared to the dominant hand was 8.99.

CONCLUSION

The risk of bleeding following extracapsular tonsillectomy with electrocautery on the side of the surgeon's nondominant hand is significantly higher than on the side of the dominant hand. Thus, additional caution is required when operating on the nondominant side of the oral cavity in extracapsular tonsillectomy using electrocautery. These findings raise questions regarding dexterity as a risk factor for posttonsillectomy bleeding.

Complications associated with PlasmaBlade TnA during tonsillectomy and adenoidectomy from 2010 to 2020: A MAUDE study

PURPOSE

The pulsed-electron avalanche knife (PEAK) PlasmaBlade TnA (Medtronic, n.d.) is a relatively new electrosurgical technology that is used widely in head and neck surgery (Medtronic Manuals, n.d.). This study aims to summarize device malfunctions, patient complications, and subsequent interventions related to PEAK PlasmaBlade TnA during tonsillectomy and adenoidectomy.

MATERIALS AND METHODS

The US Food and Drug Administration's Manufacture and User Facility Device Experience database was queried for reports of PlasmaBlade TnA adverse events from June 6, 2009, to August 30, 2020. Data were extracted from reports pertaining to tonsillectomy with or without adenoidectomy.

RESULTS

128 reports were identified, from which 163 adverse events were extracted. Of these, 23 (14.6%) were related to patients, and 140 (85.4%) were related to device malfunction. The most frequently reported patient-related adverse event was a burn injury (17 [73.9%]). The most common device malfunctions were dislodgment of device component (39 [27.9%]), followed by tip ignition (32 [22.9%]), damaged tip or wire during operation (28 [20%]), and melted device (24 [17.1%]).

CONCLUSIONS

PEAK PlasmaBlade TnA have demonstrated utility in tonsillectomy with or without adenoidectomy but are associated with adverse events. Interventions aimed at improving both physician and patient education may help reduce adverse events attributed to improper use. Further study is needed to clarify optimal approaches to education.

Predictors of Occurrence and Timing of Post-Tonsillectomy Hemorrhage: A Case-Control Study

OBJECTIVE

To describe cases and timing of pediatric post-tonsillectomy hemorrhage (PTH), to evaluate predictors of PTH, and to determine the optimal amount of postoperative care unit (PACU) monitoring time.

STUDY DESIGN

Using the Pediatric Health Information System (PHIS) database and electronic medical records, a matched case-control study from 2005 to 2015 was performed.

SETTING

A single, tertiary-care institution.

SUBJECTS AND METHODS

Each case of PTH was matched with 1 to 4 controls for the following factors: age, sex, surgeon, and time of year. A total of 124 cases of PTH and 479 tonsillectomy controls were included. The rate and timing of postoperative bleeding were assessed, and matched pair analysis was performed using conditional logistic regression.

RESULTS

Our institutional PTH rate of 1.9% (130 of 6949) included 124 patients; 15% (19) were primary (≤24 hours), with 50% (9) occurring within 5 hours. Twenty-one percent (4 of 19) of primary PTH patients received operative intervention. Eighty-five percent (105 of 124) of all cases were secondary PTH, and 47% (49) of those patients received operative intervention. Cold steel (OR 1.9, 95% CI 1.1-3.3) and Coblation (OR 1.9, 95% CI 1.2-3.1) techniques and tonsillectomy alone (OR 3.7, 95% CI 1.9-7.2) increased odds of PTH. Patients who developed PTH had 4 times the odds of having a preceding postoperative respiratory event than controls (OR 4.0, 95% CI 1.6-10.0).

CONCLUSION

We conducted a rigorous case-control study for PTH, finding that PTH was associated with use of cold steel and Coblation techniques and with tonsillectomy alone. Patients with a postoperative respiratory event may be more likely to develop a PTH and should be counseled accordingly. A PACU monitoring time of 4 hours is sufficient for outpatient tonsillectomy.

Recovery After Adenotonsillectomy-Do Steroids Help? Outcomes From a Randomized Controlled Trial

OBJECTIVES

The primary objective was to compare pain control following adenotonsillectomy (AT) in children with and without a single postoperative dose of oral dexamethasone in addition to standard analgesic medication. The secondary objective was to compare changes in caregiver-reported snoring, return to normal diet and baseline function, and the number of phone calls and emergency department (ED) visits.

STUDY DESIGN

Prospective randomized controlled trial.

SETTING

Tertiary care university hospital.

METHODS

Children aged 3 to 10 years with sleep-disordered breathing who were scheduled to undergo AT were randomized to receive standard analgesia with or without dexamethasone (0.6 mg/kg) administered on the third postoperative day. Standard analgesia was defined as alternating weight-based doses of ibuprofen and acetaminophen. A nurse practitioner blinded to the study condition performed telephone surveys postoperatively, and the electronic medical record was reviewed.

RESULTS

Enrollment comprised 149 children, of whom 119 were included. When compared with the control group (n = 61, 51%), children who received dexamethasone (n = 58, 49%) had a greater decrease in reported pain score on day 4 (mean ± SD, 2.5 ± 3.1 vs 1.1 ± 3.5, P < .001). Additionally, steroid use was associated with fewer caregiver phone calls (18 [29.5%] vs 6 [10%]) and ED visits (6 [10%] vs 1 [2%]).

CONCLUSION

A single dose of dexamethasone administered on day 3 after adenotonsillectomy significantly improved pain control. There were fewer phone calls and ED visits in the steroid arm. These results support the use of oral steroids as an adjunct for postoperative pain control in children undergoing AT.

Pediatric Obstructive Sleep Apnea and Neurocognition

Pediatric obstructive sleep apnea affects a large number of children and has multiple end-organ sequelae. Although many of these have been demonstrated to be reversible, the effects on some of the organ systems, including the brain, have not shown easy reversibility. Progress in this area has been hampered by lack of a preclinical model to study the disease. Therefore, perioperative and sleep physicians are tasked with making a number of difficult decisions, including optimal surgical timing to prevent disease evolution, but also to keep the perioperative morbidity in a safe range for these patients.

Bilateral reduction mammaplasty with pulsed electron avalanche knife PlasmaBlade™ and conventional electrosurgical surgery: A retrospective, randomised controlled clinical trial

Wound-healing disorders are common complications in bilateral reduction mammaplasty. Traditional electrosurgical devices generate large amounts of thermal energy, often causing extensive thermal-related collateral tissue damage. This study aimed to retrospectively analyse the operative performance of a novel low-thermal plasma dissection device (pulsed electron avalanche knife-PEAK PlasmaBlade™) compared with traditional electrosurgery. Twenty patients with breast hypertrophy were randomly treated with PEAK PlasmaBlade™ on one breast and conventional electrosurgery on the other. Primary outcome measures were resection weight, drain duration, total drainage volume, and drain output on the first postoperative day. Breasts treated with PEAK PlasmaBlade™ had significantly higher resection weights (728.0 ± 460.1 g vs 661.6 ± 463.4 g; P = .038), significantly lower drain output on the first postoperative day (15.9 ± 15.2 mL vs 27.6 ± 23.5 mL; P = .023), and significantly lower drain durations (2.8 ± 1.0 days vs 3.3 ± 1.0 days; P = .030). Mean total drainage volume was lower where breast reduction was performed with PEAK PlasmaBlade™, but this difference was not significant. No major complications occurred, but wound-healing disorders were documented in almost one-third of the patients (35.0%, n = 7). The PEAK PlasmaBlade™ seems to be superior to conventional electrosurgery for bilateral reduction mammaplasty in terms of tissue damage and wound healing.

PEAK PlasmaBlade versus monopolar electrocautery tonsillectomy in adults: A prospective double-blinded randomized controlled trial

OBJECTIVE

To evaluate the efficacy and compare postoperative pain and recovery following PEAK PlasmaBlade and monopolar electrocautery tonsillectomy in adults.

STUDY DESIGN

Prospective double-blinded randomized controlled trial.

METHODS

Fifty-eight patients were recruited and randomized into 2 groups: PEAK PlasmaBlade (n = 29) or monopolar electrocautery (n = 29) tonsillectomy. Postoperative pain, complications, patient satisfaction, number of tablets of analgesia taken and days taken to return to soft diet, normal diet, normal activities and achieve pain-free swallowing were compared and analysed, with the aid of a pain diary given to patients. Statistical analysis was performed with SPSS 13.0 with statistical significance set at P < 0.05.

RESULTS

Patients in the PEAK PlasmaBlade group were able to achieve pain-free swallowing in a shorter time compared to the electrocautery group (13.28 versus 15.76 days, P = 0.035). Patients were also more satisfied with PEAK PlasmaBlade tonsillectomy (P = 0.046). No significant differences in the incidence of postoperative haemorrhage, daily visual analog score for pain, number of tablets of analgesia taken and time taken to return to soft diet, normal diet and activities were seen for both groups.

CONCLUSIONS

This study showed that PEAK PlasmaBlade tonsillectomy has a faster recovery period in terms of time taken to achieve pain-free swallowing and may offer advantages when compared to monopolar electrocautery tonsillectomy.

Postoperative Pain and 14-Day Recovery in Children Undergoing Adenotonsillectomy: Low Thermal Damage Device Versus Electrosurgery

This was a randomized controlled trial of low thermal damage device versus traditional electrosurgery in children 3 to 17 years old with a clinical diagnosis of sleep disordered breathing, obstructive sleep apnea with adenotonsillar hypertrophy, or recurrent adenotonsillitis. Pain score (Wong-Baker FACES pain scale) was recorded each morning before eating, drinking, or administering pain medication for 14 days postoperatively. Seventy-five children were enrolled. There was no difference in the rate of decrease in pain scores. A significant interaction between rate of pain decrease and number of pain medication doses was present ( P < .0001). Median number of pain medication doses was greater with electrosurgery (36, range: 7-49) versus low thermal device (21, range: 2-124; P = .001). Pain scores reached 0 after a median of 7 days (95% confidence interval [CI], 5.2-8.6) for low thermal device and 9 days (95% CI, 8.0-10.0) for electrosurgery ( P = .67). One child randomized to electrosurgery was withdrawn due to hospitalization for postoperative bleed. In children, low thermal device results in significantly less pain medication used during the postoperative period than electrosurgery.

Post-tonsillectomy hemorrhagic outcomes in children with bleeding disorders at a single institution

OBJECTIVE

To report on the post-tonsillectomy bleeding outcomes and factors associated with hemorrhage among children with pre- or post-operatively diagnosed bleeding disorders treated with an institutional protocol.

METHODS

Retrospective cohort study of patients with hematologic disorders who underwent tonsillectomy between 2003 and 2016 and were treated with perioperative desmopressin or factor replacement and/or aminocaproic acid. Postoperative outcomes were compared to controls matched for age, sex, and indication for surgery. Analysis of factors associated with hemorrhage was performed in patients with bleeding disorders using Mann-Whitney U or chi-squared tests.

RESULTS

45 patients with hematologic disorders met inclusion criteria. Platelet dysfunction, including von Willebrand Disease (vWD), was the most common diagnosis (77.8%). Most patients had a preoperative diagnosis of a bleeding disorder and received perioperative hematologic medications (86.7%). Compared to matched controls, patients with hematologic disorders experienced more postoperative bleeding (15.5%; 12 bleeds, 7 patients vs. 1.7%; 1 bleed, 1 patient, p = 0.05) and had longer postoperative stays (1.3 days vs. 0.4 days, p < 0.001). Among the patients with hematologic disorders, patients who experienced a postoperative bleed were significantly more likely to have a factor deficiency (e.g. Hemophilia over vWD) and have a postoperative diagnosis (compared to preoperative diagnosis) for which they did not receive perioperative hematologic medication. Of patients with a postoperative bleed, all those diagnosed postoperatively required at least one surgical intervention to control bleeding compared to 33% of patients with a preoperative diagnosis. A history of post-surgical bleeding, male sex, age at surgery, and pharyngitis as surgical indication were not associated with higher hemorrhage rates in this group.

CONCLUSIONS

This study suggests a clinically important magnitude of increased bleeding risk in patients with hematologic disease. This risk appears to decrease with the use of an institutional protocol consisting of desmopressin or factor replacement and an antifibrinolytic agent extending through postoperative day 10.

The effect of tonsillotomy on chronic recurrent tonsillitis in children

OBJECTIVES

The objective of this study is to determine whether partial tonsillectomy (tonsillotomy) impacts the occurrence of acute or recurrent tonsillitis in children.

METHODS

One hundred and eighty patients (1-14 years) were retrospectively surveyed by a questionnaire or by data analysis of a regional database. Subjects who suffered from severe systemic diseases or immunodeficiency syndromes were excluded. Episodes of acute tonsillitis before and after surgery, rate of antibiotic treatment, postoperative hemorrhage, and re-operation were obtained.

RESULTS

Fifty-one patients suffered from preoperative tonsillitis. The rate of reinfection was 9.8%. The frequency of tonsillitis was significantly reduced in children after tonsillotomy (p < .001). Further, tonsillotomy led to a significant reduction of antibiotic treatment (p < .001). The rate of definitive tonsillectomy was 1.1% and thus effectiveness was very high. About 1.7% of all children suffered from postoperative bleeding, of which one (0.6%) required surgical revision. None of the bleedings was life threatening.

CONCLUSIONS

Tonsillotomy is beneficial for patients with recurrent tonsillitis and carries less risk of postoperative complications than tonsillectomy.

Use of intranasal corticosteroids in adenotonsillar hypertrophy

Objectives:

This review examined the efficacy of intranasal corticosteroids for improving adenotonsillar hypertrophy.

Method:

The related literature was searched using PubMed and Proquest Central databases.

Results:

Adenotonsillar hypertrophy causes mouth breathing, nasal congestion, hyponasal speech, snoring, obstructive sleep apnoea, chronic sinusitis and recurrent otitis media. Adenoidal hypertrophy results in the obstruction of nasal passages and Eustachian tubes, and blocks the clearance of nasal mucus. Adenotonsillar hypertrophy and obstructive sleep apnoea are associated with increased expression of various mediators of inflammatory responses in the tonsils, and respond to anti-inflammatory agents such as corticosteroids. Topical nasal steroids most likely affect the anatomical component by decreasing inspiratory upper airway resistance at the nasal, adenoidal or tonsillar levels. Corticosteroids, by their lympholytic or anti-inflammatory effects, might reduce adenotonsillar hypertrophy. Intranasal corticosteroids reduce cellular proliferation and the production of pro-inflammatory cytokines in a tonsil and adenoid mixed-cell culture system.

Conclusion:

Intranasal corticosteroids have been used in adenoidal hypertrophy and adenotonsillar hypertrophy patients, decreasing rates of surgery for adenotonsillar hypertrophy.
