A national survey of the anesthetic management of tonsillectomy surgery in children

Cauterization tonsillectomy as compared to traditional tonsillectomy technique

Background:

Tonsillectomy is one of the most frequently applied and oldest surgical procedures in otorhinolaryngology. Various surgical techniques are used to perform this operation including traditional and cauterization techniques.

Objectives:

To assess morbidity and efficacy and compare objectively the techniques in tonsillectomy, i.e., traditional technique and cauterization technique. This study compares the traditional and cauterization tonsillectomy techniques in view of their advantages and complications.

Methods:

This is a retrospective study and comparative study, conducted during the period from January 2017 to March 2018 from the patients attending to Alnamas General Hospital, Aseer Region, Saudi Arabia. The questionnaire was designed to compare the traditional and cauterization tonsillectomy. Fifty patients underwent traditional technique and fifty patients underwent cauterization method. The data analyzed using SPSS V.16.0 (SPSS Inc; Chicago, IL, USA).

Results:

A total of 100 patients, 62 males and 38 females, aged 8 to 16 years were included in the study. A total of 100 patients were enrolled in the study. Traditional and cauterization tonsillectomy were performed. 50 (27 male and 23 female) patients, whose ages ranged from 9 to 16 years old underwent the traditional tonsillectomy, 50 (35 male and 15 female) patients whose ages ranged from 8 to 16 years underwent cauterization. The two groups were similar for demographic parameters. The difference between mean operative times of the two methods was statistically significant. Postoperative bleeding is significantly higher in the traditional technique compared to cauterization method. Postoperative pain is significantly less in cauterization method. Only a few patients experienced fever, bleeding, and other complications related to anesthesia. The bleeding severity is significantly lower in the cauterization technique. Postoperative pain was less in cauterization technique on day 1 and day 5. Postoperative pain was from mild to severe.

Conclusion:

This study revealed significantly less postoperative complications in traditional tonsillectomy in comparison with the cauterization method. Healing time was significantly faster in cauterization technique than in traditional method.

How Pediatric Anesthesiologists Manage Children with OSA Undergoing Tonsillectomy

OBJECTIVE

The purpose of this study was to describe typical anesthesia practices for children with obstructive sleep apnea (OSA).

STUDY DESIGN

Online survey.

METHOD

A sample of pediatric anesthesiologists received the survey by email.

RESULTS

110 respondents were included. 46.4% worked in a free-standing children's hospital and 32.7% worked in a children's facility within a general hospital. 73.6% taught residents. 44.4% saw at least one child with OSA per week, 25.5% saw them daily. On a 100-mm visual analog scale, respondents rated their comfort with managing these children as 84.94 (SD 17.59). For children with severe OSA, 53.6% gave oral midazolam preoperatively, but 24.5% typically withheld premedication and had the parent present for induction. 68.2% would typically use nitrous oxide for inhalational induction. 68.2% used fentanyl intraoperatively, while 20.0% used morphine. 61.5% reduced their intraop narcotic dose for children with OSA. 98.2% used intraoperative dexamethasone, 58.2% used 0.5 mg/kg for the dose. 98.2% used ondansetron, 62.7% used IV acetaminophen, and 8.2% used IV NSAIDs. 83.6% extubated awake. 27.3% of respondents stated that their institution had standardized guidelines for perioperative management of children with OSA undergoing adenotonsillectomy. People who worked in children's hospitals, who had >10 years of experience, or who saw children with OSA frequently were significantly more comfortable dealing with children with OSA (P < 0.05).

CONCLUSION

Apart from using intraoperative dexamethasone and ondansetron, management varied. These children would likely benefit from best practices perioperative management guidelines.

Comparison of Cold Technique Tonsillectomy and Thermal Welding Tonsillectomy at Different Age Groups

The aim of this study is to compare objectively advantages and disadvantages of cold technique tonsillectomy and thermal welding tonsillectomy at the same case. A total of 100 patients, 53 patients younger than 12 years of age and 47 patients elder than 12 years of age, were included in this study. Tonsillectomy was performed by using cold technique on the right side of the palatine tonsils and thermal welding on the left side. Right and left sides were compared regarding perioperative bleeding, surgical dissection time, postoperative pain scale at the 1st and 7th day and postoperative bleeding parameters. Perioperative bleeding was found to be higher in cold technique side in patients younger than 12 years of age (p&lt;0.001). Postoperative pain score on the day 1 was significantly higher in cold technique side, whereas it was found to be higher in thermal welding side at postoperative day 7 (p&lt;0.001). Perioperative bleeding was found to be significantly higher in cold technique side (p&lt;0.001) and surgical dissection time of thermal welding was found to be longer (p&lt;0.001) in patients elder than 12 years of age. Postoperative pain score at the day 1 and day 7 was found to be higher in thermal welding side (p&lt;0.001). Postoperative pain score at the day 1 and day 7 were statistically significantly higher in patients elder than 12 years of age. As a result, both techniques have its unique superior aspects and both can be applied as a routine tonsillectomy technique.

Use of Succinylcholine by Anaesthetists in Turkey: A National Survey

OBJECTIVE

Although succinylcholine (SCh) has side effects, it is among the most commonly used muscle relaxants for rapid induction because of the faster onset of its effects and short effect duration. However, there is no information regarding the frequency of use of SCh by anaesthetists in Turkey. This study aims to investigate the use of SCh by anaesthetists working in Turkey.

METHODS

A web-based survey form was sent by e-mail to anaesthetists working in Turkey. The form comprised a total of 24 questions.

RESULTS

E-mails were sent to a total of 1882 addresses at two separate times. E-mail replies were received from 433 (23%) anaesthetists. Based on those who responded to the survey, 54.27% anaesthetists routinely used SCh for adult elective cases, 29.33% for paediatric elective cases and 74.13% for emergency cases. In adult elective cases, SCh was most frequently chosen for caesarean section (20.5%), and in paediatric elective and emergency cases, SCh was chosen most frequently because difficult intubation was expected (31.3 and 21.4%, respectively).

CONCLUSION

Our study reveals that SCh is still widely used by anaesthetists in Turkey. Majority of physicians who participated our survey were aware of the side effects; however, they reported using SCh in certain special situations. It is evident that creation of a standard care guide for departments is essential. The first stage of creating a standard care guide is to analyse and document the current application. With this aim, more wide-ranging advanced studies should be completed.

INFLUENCE OF OVERWEIGHT AND OBESITY IN CHILDREN ON ANESTHESIOLOGICAL COMPLICATIONS APPEARANCE DURING ADENOIDECTOMY AND ADENOTONSILLECTOMY

INTRODUCTION

Obesity in children is becoming from year to year enormous medical and socio-epidemilogical problem according to increasing number of overweight and obese children. Overweight and obesity in children mostly affects on cardiovascular, respiratory and endocrine system disturbances. Adenoidectomy and adenotonsillectomy belong to group of most often done operation in children population. Anesthesiology complications during adenodecotomy and adenotonsillectomy in children are known as very disturbing and dramatic.

METHODS

Retrospective-prospective study includes 162 children, both genders, 3 to 12 years old, who are hospitalized and operated (adenoidectomies and adenotonsillectomies) on Otorihinolaryngolic clinic of University clinical centre Tuzla in the four year period. Purpose of the study is to show the influence of overweight in children on appearance of anesthesiology complications such as difficult intubation, bronchospasm and laryngospasm. Body mass index (BMI), which is used as universal measure, is adapted with gender specific scales of National statistic centre of United States of America. All children with BMI over 25 are referred as overweight and those over 30 as obese. These children categories were compared to those with normal BMI according to anesthesiology complications incidence.

RESULTS

Overweight in operated children is noticed in 21%, and 11% of children was obese and there wasn't distinction between boys and girls. Anesthesiology complications are evaluated in 12 of them (7.4%). Total analyzed sample show significant connection and influence of overweight with appearance of anesthesiology complications. Separate comparison for two types of operations is indicating that during adenoidectomies there hasn't been noticed connection between overweight and anestehesiological complications, while in case of adenotonsillectomies direct and significant correlation is proven.

CONCLUSIONS

According to increased risk of anesthesiology complications in overweight and obese children during adenodectomies and adenotonsillectomies it is important for anesthesiologists to do much serious preoperative evaluation of obese children, and to be more prepared for every of possible unwished supersize during perioperative period.

Routine tonsillar bed oversew after diathermy tonsillectomy: does it reduce secondary tonsillar haemorrhage?

Tonsillectomy is a common otolaryngological procedure and is associated with a small risk of postoperative pharyngeal haemorrhage. This study compares secondary post tonsillectomy haemorrhage rates between two operative techniques: diathermy tonsillectomy and diathermy tonsillectomy with tonsillar bed oversew. A total of 424 patients underwent tonsillectomies with or without other procedures such as adenoidectomy and grommet insertion by two ears, nose and throat surgeons at three hospitals from May 2012 to July 2013. A diathermy tonsillectomy was performed in 266 patients, while a diathermy tonsillectomy with tonsillar bed oversew was performed in 158 patients. All patients were followed up within 2-4 weeks of surgery. Primary haemorrhage did not occur in either surgical technique groups. Secondary haemorrhage occurred in 20 patients (7.52 %) in the diathermy tonsillectomy group and in 9 patients (5.70 %) in the diathermy with tonsillar bed oversew group. This result was not significantly different (OR = 0.74, 95 % CI 0.33-1.67, p = 0.47). Sex, age, indication for surgery and whether or not a tonsillectomy was performed alone or with other procedures were not significant factors for secondary haemorrhage. In summary, routine tonsillar bed oversew after diathermy tonsillectomy does not reduce the risk of secondary tonsillar haemorrhage.

Postoperative pain during the first week after adenoidectomy and guillotine adenotonsillectomy in children

BACKGROUND

Adenoidectomy (AD) and adenotonsillectomy (ATE) are frequently occurring and often painful interventions in children. In literature, it is very prevalent that postoperative pain in children following ATE is hard to control. The purpose of this study was to evaluate the prevalence and severity of postoperative pain in children undergoing AD and ATE in the ambulatory setting.

METHODS

A prospective cohort study was performed including 167 children aged 0-12 years, undergoing AD using an adenotome and ATE using the guillotine technique in day care. Children undergoing AD received acetaminophen pre- and postoperatively. Children undergoing ATE received acetaminophen and diclofenac preoperatively, sufentanyl postoperative and a prescription of around-the-clock treatment with acetaminophen and diclofenac at home. Pain intensity and analgesic consumption were recorded in hospital using the Faces, Legs, Activity, Cry and Consolability-scale (FLACC), as well as during a 1-week follow-up period at home using the Parents' Postoperative Pain Measure (PPPM) and Visual Analogue Scale (VAS) scores.

RESULTS

All children left the recovery room with adequate pain scores and were discharged with a median VAS of two after ATE and one after AD. The PPPM and VAS scores were highest at the first measurement at home for AD patients (VAS = 2.0 and PPPM = 1.5) and ATE patients (VAS = 4.5 and PPPM = 9). On the second postoperative day, AD patients scored 0.0 points on both VAS and PPPM. ATE patients scored at that time 3.0 point on the VAS and 6.0 points using the PPPM. Despite high adherence to pain treatment, daytime activities normalized after an average of 2 and 7 days after AD and ATE, respectively.

CONCLUSION

Examination of the PPPM and VAS scores illustrated that children undergoing AD were comfortable with acetaminophen as a single analgesic, whereas children undergoing ATE experience significant pain for up to two postoperative days when treated with acetaminophen and diclofenac.

Acupuncture instead of codeine for tonsillectomy pain in children

OBJECTIVES

Severe throat pain can result from tonsillectomy and last up to 10 days in children. Codeine elixir has long been used for pain relief, but has recently been banned by the Food and Drug Administration due to a recently recognized risk of death. We explored acupuncture as an alternative means of pain relief for children and adolescents after tonsillectomy.

METHODS

This was a retrospective review of children and adolescents who underwent tonsillectomy over a three-month period. No narcotics were prescribed after surgery. Patients who wanted help with pain relief were offered acupuncture. Perceived pain level was assessed before and after the acupuncture treatment. Following the 10-day recovery for tonsillectomy, patients or their parents were queried as to how long the pain relief from acupuncture intervention was perceived to last.

RESULTS

56 children and adolescents underwent tonsillectomy in the three-month window selected for the retrospective review. 31 of these patients (ranging from 2 to 17 years in age) received an acupuncture intervention for postoperative pain. The mean reported pain level before acupuncture was 5.52 (SD = 2.28) out of 10. This fell to 1.92 (SD = 2.43) after acupuncture. Statistical analysis supported the general conclusion that pain reports decline after acupuncture in the sampled population. However, the limitations of the methodology and the sample suggest that this generalization should be treated as preliminary. 17 patients or their parents provided a post-recovery report for how long they believed the acupuncture intervention lasted. The mean duration of perceived acupuncture benefit was 61.24 h, though the standard deviation was large (64.58 h) with about 30% of patients reporting less than three hours of benefit and about 30% reporting more than 60 h. No adverse effects were observed as a result of acupuncture treatments.

CONCLUSIONS

The data tentatively suggest that acupuncture decreases perceived pain in children and adolescents after tonsillectomy. These data - combined with the cost effectiveness, safety and ease of administering acupuncture - suggest that further studies exploring the effectiveness of acupuncture in juveniles after tonsillectomy are merited.

Comparison of three techniques in adult tonsillectomy

This study aimed at investigating the thermal welding (TW), classic dissection (CD) and bipolar cautery dissection (BCD) tonsillectomy in adults. 120 adults with chronic tonsillitis, who were scheduled for elective tonsillectomy between January 2009 and April 2012, were randomized to tonsillectomy with the TW, CD and BCD methods. Operation time, intraoperative blood loss, post-operative haemorrhage rate and especially post-operative pain were evaluated. The difference between operative time of the TW and BCD groups against CD group was statistically significant (p < 0.05). The difference between intraoperative blood loss of the TW and BCD groups against CD group was statistically significant (p < 0.05). No significant difference was found in the incidence of post-tonsillectomy haemorrhage between the three groups (p > 0.05). The difference between post-operative pain score between CD and TW was not statistically significant (p > 0.05). The difference between post-operative pain score of the two groups against BCD group was statistically significant (p < 0.05). TW technique is a relatively safe and reliable method with significantly less post-operative morbidity than CD and BCD tonsillectomy. When we compared TW with the CD and BCD tonsillectomy, we found significant reduction in the surgical time and the intraoperative blood loss without any increase in the post-operative pain.

A comparison between dexamethasone and methylprednisolone for vomiting prophylaxis after tonsillectomy in inpatient children: a randomized trial

BACKGROUND

The frequent incidence of postoperative vomiting in children undergoing tonsillectomy, in addition to the occurrence of severe pain, may delay postoperative oral intake and lead to increased risk of dehydration. Thus, prophylactic therapy is indicated in this high-risk group. Glucocorticoids, such as dexamethasone and methylprednisolone, have anti-inflammatory and antiemetic properties with dexamethasone being frequently used. We hypothesized that methylprednisolone should be noninferior to dexamethasone for the prevention of vomiting in children after tonsillectomy.

METHODS

We designed a randomized double-blind trial to compare the efficacy of a single prophylactic dose of 0.5 mg/kg dexamethasone with a dose of 2.5 mg/kg methylprednisolone on the incidence of postoperative vomiting during the first 24 hours (primary outcome) in children undergoing total or partial tonsillectomy with a noninferiority margin set at 9%. One hundred sixty children undergoing total or partial tonsillectomy under general anesthesia were randomly assigned to receive either IV dexamethasone 0.5 mg/kg (n = 79) or methylprednisolone 2.5 mg/kg (n = 81) after induction of anesthesia. Secondary analysis of all studied outcomes was also performed according to the type of surgery.

RESULTS

An intention-to-treat analysis showed an overall incidence of vomiting of 30% in the dexamethasone group and of 22% in the methylprednisolone group (difference: 8%, 95% confidence interval [CI]: -5% to 21%). A per protocol analysis showed an incidence of vomiting of 32% and 23%, respectively (difference: 9%, and 95% CI of the difference: -5 to 23%, P(sup) = 0.28). The time and quality of oral intake and the duration of IV hydration, as well as pain and satisfaction scores and the need for analgesics, were similar between the 2 groups. The incidence of vomiting was also similar in patients who had total versus partial tonsillectomy; however, time to first oral intake, duration of IV hydration, and the need for analgesics were less with better satisfaction scores in partial versus total tonsillectomy patients.

CONCLUSION

Methylprednisolone is at worst 5% less effective than dexamethasone by the intention-to-treat analysis, and by the per protocol analysis. Thus, it is noninferior to dexamethasone in preventing vomiting after tonsillectomy in children.

A randomised controlled trial of two analgesic techniques for paediatric tonsillectomy*

Investigators from Bristol described a fentanyl- and diclofenac-based analgesic technique for tonsillectomy with low postoperative nausea and vomiting rates and low pain scores. This study compared the effectiveness of a modified Bristol technique with a codeine-based regimen with respect to PONV and analgesia. Sixty-five children, ASA 1-2, were randomly assigned to either the Bristol group (fentanyl 1-2 μg.kg(-1) and diclofenac 1-2 mg.kg(-1)) or codeine group (codeine 1.5 mg.kg(-1)). All children received paracetamol 15 mg.kg(-1) and dexamethasone 0.1 mg.kg(-1) . Postoperative nausea and vomiting and pain scores were recorded hourly, and fitness for discharge was assessed at 4 h. The overall incidence of postoperative nausea and vomiting was 21% with no difference between groups (Bristol group 8/30, codeine group 5/32, p = 0.29). Children in the Bristol group required analgesia earlier than those in the codeine group (p < 0.005), but maximum pain scores were not different (Bristol group median (IQR [range) 4.5 (3-5 [0-5]), codeine group 4.0 (2-5 [1-5]), p = 0.15). Twenty-three per cent of children were assessed as not fit for discharge at 4 h. The codeine-based regimen may have a small advantage over the Bristol regimen, but neither technique seems ideally suited for a day-case service without a longer period of observation.

Dexamethasone and Tonsillectomy Bleeding

Objective. To use meta-analytic techniques to examine the effect of dexamethasone on the risk of postoperative bleeding following tonsillectomy.

Data Sources. PubMed and Embase databases accessed on April 23, 2009, and April 28, 2009.

Review Methods. Using principles of meta-analysis, inclusion and exclusion criteria were developed to identify all randomized controlled trials of patients undergoing tonsillectomy in which perioperative intravenous dexamethasone was administered in at least 1 treatment arm and bleeding complications were reported. Electronic databases were searched to identify candidate articles. Two authors independently abstracted data from each article. Discrepancies were resolved by consensus. A fixed-effects model was used to pool relative risks among studies using the Mantel-Haenszel method. Studies were assessed for publication bias using a funnel plot of studies’ effect size vs standard error of the effect size as well as Begg test and Egger test. A P value <.05 was considered significant.

Results. The primary search identified 85 potential studies. Fourteen met inclusion criteria and were selected for meta-analysis. No significant heterogeneity was found among studies (I2< 0.1%; 95% confidence interval [CI], 0%-55%; P = .68). The pooled relative risk (RR) of postoperative bleeding did not differ significantly between patients receiving dexamethasone and controls (RR, 1.02; 95% CI, 0.65-1.61; P = .92). When studies were stratified by age, primary vs secondary hemorrhage, and follow-up duration, no further significant differences in bleeding rate were identified. No evidence of publication bias was found using Begg ( P = .70) or Egger ( P = .73) tests.

Conclusion. The results of this meta-analysis indicate that perioperative dexamethasone does not confer an increased risk of postoperative bleeding in patients undergoing tonsillectomy.

Anesthesia for pediatric airway surgery: recommendations and review from a pediatric referral center

Pediatric airway surgery presents many significant challenges to the anesthesia provider. The clinical experience of the Massachusetts Eye and Ear Infirmary serves as a guide in this review to describe the clinical reasoning and perioperative management of the pediatric patient needing airway surgery, with specific emphasis on diagnostic procedures, trauma, laryngotracheal reconstruction, juvenile recurrent respiratory papillomatosis, and adenotonsillectomy.

Challenges in pediatric ambulatory anesthesia: kids are different

The care of the child having ambulatory surgery presents a specific set of challenges to the anesthesia provider. This review focuses on areas of clinical distinction that support the additional attention children often require, and on clinical controversies that require providers to have up-to-date information to guide practice and address parental concerns. These include perioperative risk; obstructive sleep apnea; obesity; postoperative nausea and vomiting; neurocognitive outcomes; and specific concerns regarding common ear, nose, and throat procedures.

Laryngeal mask airways in ear, nose, and throat procedures

The use of laryngeal mask airway (LMA) and its variants in ear, nose, and throat procedures have been extensively described in case reports, retrospective reviews, and randomized clinical trials. The LMA has developed a considerable following because of its lack of tracheal stimulation, which can be a considerable advantage in ear, nose, and throat (ENT) procedures. The incidence of coughing on emergence has been shown to be lower with the LMA than with the endotracheal tube (ETT). Although other approaches to smooth emergence have been described, few would argue that it is as easy to achieve a smooth emergence with an ETT as with an LMA. Although patients certainly exist for whom the LMA is contraindicated, many will experience better results with the LMA because of the features delineated in this article.
