The effect of preoperative fasting on postoperative pain, nausea and vomiting in pediatric ambulatory tonsillectomy

Effect of Preoperative Clear Liquid Consumption on Postoperative Recovery in Pediatric Patients Undergoing Minimally Invasive Repair of Pectus Excavatum: A Prospective Randomized Controlled Study

Background/Objectives: Preoperative fasting guidelines traditionally aim to reduce pulmonary aspiration risk. However, concerns over the adverse effects of prolonged fasting have led to exploring alternatives. This study aimed to investigate the impact of preoperative clear liquid intake on postoperative outcomes in children undergoing minimally invasive repair of pectus excavatum (MIRPE). Methods: A prospective randomized controlled study was conducted on children aged 3-6 years scheduled for elective MIRPE. Patients were randomized into either a routine overnight fasting group (NPO) or a clear liquid group. The incidence and severity of emergence delirium (ED) were assessed using Pediatric Anesthesia Emergence Delirium (PAED) and Watcha scales at recovery room. Postoperative pain scores and opioid requirements were evaluated at intervals of 1-6 h, 6-12 h, and 12-24 h after surgery. Results: Fasting time was 178.6 ± 149.5 min and 608.9 ± 148.4 min in the clear liquid group compared and NPO group, respectively. The incidence of ED, measured by PAED and Watcha scales, was lower in the clear liquid group (PAED score ≥ 12: 55.6% vs. 85.2%, p = 0.037; Watcha score ≥ 3: 51.9% vs. 85.2%, p = 0.019). The highest PAED score recorded in the recovery room was significantly lower in the clear liquid group (11.4 ± 2.8 vs. 14.6 ± 2.8, p < 0.001). Clear liquid group showed significantly lower pain scores at 1-6, 6-12, and 12-24 h postoperatively. Additionally, clear liquid group had lower opioid requirement at 1-6 and 6-12 h postoperatively. Conclusions: Preoperative clear liquid consumption was associated with a lower incidence of ED in pediatric patients undergoing MIRPE.

Nausea and Vomiting After Laparoscopic Cholecystectomy: Analysis of Predictive Factors

PURPOSE

The purpose of this study was to identify the factors predictive of postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy.

DESIGN

This is a descriptive, cross-sectional study.

METHODS

In total, 172 patients completed the study. "The Questionnaire Form," "Visual Analog Scale," "Nausea Scale," and "Anxiety Specific to Surgery Questionnaire" created by the researchers were used for data collection.

FINDINGS

At the second postoperative hour, 55.8% of the patients had nausea, 20.3% had vomiting and 75% had severe pain. The severity of nausea, vomiting, and pain decreased with time. Age, gender, smoking, motion sickness, postoperative pain, opioid use, preoperative fasting time, time of first postoperative fluid intake and preoperative anxiety score were found to be among the factors predictive of PONV (P < .05).

CONCLUSIONS

High rates of postoperative nausea and vomiting were recorded.  The factors predictive of PONV can be evaluated in the preoperative period, and PONV can be controlled with early interventions and treatment of patients in the risk group.

Follow up of pain reported by children undergoing outpatient surgery using a smartphone application: AlgoDARPEF multicenter descriptive prospective study

ABSTRACT

In pediatric patients, pain remains the most common complaint after surgery. This French multicenter epidemiological study (AlgoDARPEF) aimed to evaluate the use of a smartphone application (App) to assess the duration and severity of pain experienced by children undergoing outpatient surgery. Children below 18 years of age scheduled for an elective outpatient procedure in one of the participating centers were eligible. Parents were invited to provide daily information for 10 days regarding their child's pain and comfort via a smartphone App using the Parents' Postoperative Pain Measure - Short Form (PPPM-SF). Children over 6 years old could also provide self-assessments of pain using a Numerical Rating Scale (NRS-11). Data regarding pain medication, preoperative anxiety, postoperative nausea and vomiting, and parent satisfaction were also analyzed. Repeated-measures analyses of variance (ANOVAs) were used to compare the self- and hetero-assessments of pain. Eleven centers participated in the study, and 1,573 patients were recruited. Forty-nine percent of parents (n = 772) actually used the App at least once. In all surgeries, the average pain rating on the PPPM-SF scale did not exceed 3/10 throughout the follow-up period, as well as for the four main surgical specialties. Age, visceral surgery, and preoperative anxiety ≥ 4/10 were identified as independent risk factors for experiencing at least one episode of pain ≥ 4/10 during the first 48 postoperative hours. While these findings indicated that postoperative pain management appears to be satisfactory in the families who used the App, some improvements in anxiety management are suggested. This study shows that inviting parents to use a smartphone App to assess and report the quality of postoperative management in pediatric patients, provides useful information. A continuous report is possible, regarding pain and adverse events, over a postoperative ten days period, by a self-reporting or a parent's contribution. Future studies should investigate the ability of live data collection using an App to ensure fast, efficient interactions between patients and physicians.

Observance of preoperative clear fluid fasting in pediatric anesthesia: oral and written information versus text message information. A before-and-after study

INTRODUCTION

Prolonged fasting before surgery is common in pediatrics. In the literature, it is responsible for hypotension, irritability and postoperative nausea and vomiting. Despite clear instructions given during the preanesthetic consultation, fasting rules are respected in only 30%-40% of cases. We aimed to evaluate the benefit of sending a text message the day before surgery to improve the parents' observance of fasting rules.

METHODS

We conducted a before-and-after study at the University Hospital of Poitiers. From August to October 2018, 172 parents of children under 15 years of age scheduled for all types of surgery were enrolled into two groups according to the period: the control group with parents receiving information on preoperative fasting rules during the preanesthetic consultation several days before surgery, and the text message group, receiving the same information during consultation plus a text message the day before the surgery.

RESULTS

There was a difference in observance of clear fluid fasting instructions (between 2 and 3 h before the admission at hospital) in favor of the text message group 33% versus 92% OR 29.2 (10.9-95.2) p < 0.001, and in average fasting time for clear fluids 8.7 h ± 4.8 h vs. 4.3 h ± 2.4 h (p < 0.001).

CONCLUSION

Sending of a reminder text message to the parents the day before the surgery resulted in a significant increase in observance of fasting rules in children undergoing scheduled surgery.

PROSPECT guideline for tonsillectomy: systematic review and procedure-specific postoperative pain management recommendations

Tonsillectomy is one of the most frequently performed surgical procedures; however, pain management remains challenging. Procedure‐specific efficacy as well as specific risks of treatment options should guide selection of pain management protocols based on evidence and should optimise analgesia without harm. The aims of this systematic review were to evaluate the available literature and develop recommendations for optimal pain management after tonsillectomy. A systematic review utilising preferred reporting items for systematic reviews and meta‐analysis guidelines with procedure‐specific postoperative pain management (PROSPECT) methodology was undertaken. Randomised controlled trials published in the English language up to November 2019 assessing postoperative pain using analgesic, anaesthetic or surgical interventions were identified. Out of the 719 potentially eligible studies identified, 226 randomised controlled trials met the inclusion criteria, excluding the studies examining surgical techniques. Pre‐operative and intra‐operative interventions that improved postoperative pain were paracetamol; non‐steroidal anti‐inflammatory drugs; intravenous dexamethasone; ketamine (only assessed in children); gabapentinoids; dexmedetomidine; honey; and acupuncture. Inconsistent evidence was found for local anaesthetic infiltration; antibiotics; and magnesium sulphate. Limited evidence was found for clonidine. The analgesic regimen for tonsillectomy should include paracetamol; non‐steroidal anti‐inflammatory drugs; and intravenous dexamethasone, with opioids as rescue analgesics. Analgesic adjuncts such as intra‐operative and postoperative acupuncture as well as postoperative honey are also recommended. Ketamine (only for children); dexmedetomidine; or gabapentinoids may be considered when some of the first‐line analgesics are contra‐indicated. Further randomised controlled trials are required to define risk and combination of drugs most effective for postoperative pain relief after tonsillectomy.

A Pilot Quality Improvement Project to Reduce Preoperative Fasting Duration in Pediatric Inpatients

Supplemental Digital Content is available in the text.

Despite guidelines allowing clear liquids up to 2 hours before anesthesia, preoperative fasting for pediatric inpatients is often unnecessarily prolonged. This delay can lead to prolonged recovery time and increased postoperative pain. Efforts to reduce fasting duration in pediatric surgical patients is an evolving standard in pediatric anesthesiology. The primary aim of this quality improvement project was to reduce the average inpatient fasting duration undergoing anesthesia by 25% within a year of our pilot intervention. Secondary aims included measuring the adoption rate of the intervention and comparing aspiration rates as a balancing measure.

Clinical Practice Guideline: Tonsillectomy in Children (Update)

OBJECTIVE

This update of a 2011 guideline developed by the American Academy of Otolaryngology-Head and Neck Surgery Foundation provides evidence-based recommendations on the pre-, intra-, and postoperative care and management of children 1 to 18 years of age under consideration for tonsillectomy. Tonsillectomy is defined as a surgical procedure performed with or without adenoidectomy that completely removes the tonsil, including its capsule, by dissecting the peritonsillar space between the tonsil capsule and the muscular wall. Tonsillectomy is one of the most common surgical procedures in the United States, with 289,000 ambulatory procedures performed annually in children <15 years of age based on the most recent published data. This guideline is intended for all clinicians in any setting who interact with children who may be candidates for tonsillectomy.

PURPOSE

The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing children under consideration for tonsillectomy and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to educate clinicians, patients, and/or caregivers regarding the indications for tonsillectomy and the natural history of recurrent throat infections. Additional goals include the following: optimizing the perioperative management of children undergoing tonsillectomy, emphasizing the need for evaluation and intervention in special populations, improving the counseling and education of families who are considering tonsillectomy for their children, highlighting the management options for patients with modifying factors, and reducing inappropriate or unnecessary variations in care. Children aged 1 to 18 years under consideration for tonsillectomy are the target patient for the guideline. For this guideline update, the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of nursing, anesthesiology, consumers, family medicine, infectious disease, otolaryngology-head and neck surgery, pediatrics, and sleep medicine.

KEY ACTION STATEMENTS

The guideline update group made strong recommendations for the following key action statements (KASs): (1) Clinicians should recommend watchful waiting for recurrent throat infection if there have been <7 episodes in the past year, <5 episodes per year in the past 2 years, or <3 episodes per year in the past 3 years. (2) Clinicians should administer a single intraoperative dose of intravenous dexamethasone to children undergoing tonsillectomy. (3) Clinicians should recommend ibuprofen, acetaminophen, or both for pain control after tonsillectomy. The guideline update group made recommendations for the following KASs: (1) Clinicians should assess the child with recurrent throat infection who does not meet criteria in KAS 2 for modifying factors that may nonetheless favor tonsillectomy, which may include but are not limited to multiple antibiotic allergies/intolerance, PFAPA (periodic fever, aphthous stomatitis, pharyngitis, and adenitis), or history of >1 peritonsillar abscess. (2) Clinicians should ask caregivers of children with obstructive sleep-disordered breathing and tonsillar hypertrophy about comorbid conditions that may improve after tonsillectomy, including growth retardation, poor school performance, enuresis, asthma, and behavioral problems. (3) Before performing tonsillectomy, the clinician should refer children with obstructive sleep-disordered breathing for polysomnography if they are <2 years of age or if they exhibit any of the following: obesity, Down syndrome, craniofacial abnormalities, neuromuscular disorders, sickle cell disease, or mucopolysaccharidoses. (4) The clinician should advocate for polysomnography prior to tonsillectomy for obstructive sleep-disordered breathing in children without any of the comorbidities listed in KAS 5 for whom the need for tonsillectomy is uncertain or when there is discordance between the physical examination and the reported severity of oSDB. (5) Clinicians should recommend tonsillectomy for children with obstructive sleep apnea documented by overnight polysomnography. (6) Clinicians should counsel patients and caregivers and explain that obstructive sleep-disordered breathing may persist or recur after tonsillectomy and may require further management. (7) The clinician should counsel patients and caregivers regarding the importance of managing posttonsillectomy pain as part of the perioperative education process and should reinforce this counseling at the time of surgery with reminders about the need to anticipate, reassess, and adequately treat pain after surgery. (8) Clinicians should arrange for overnight, inpatient monitoring of children after tonsillectomy if they are <3 years old or have severe obstructive sleep apnea (apnea-hypopnea index ≥10 obstructive events/hour, oxygen saturation nadir <80%, or both). (9) Clinicians should follow up with patients and/or caregivers after tonsillectomy and document in the medical record the presence or absence of bleeding within 24 hours of surgery (primary bleeding) and bleeding occurring later than 24 hours after surgery (secondary bleeding). (10) Clinicians should determine their rate of primary and secondary posttonsillectomy bleeding at least annually. The guideline update group made a strong recommendation against 2 actions: (1) Clinicians should not administer or prescribe perioperative antibiotics to children undergoing tonsillectomy. (2) Clinicians must not administer or prescribe codeine, or any medication containing codeine, after tonsillectomy in children younger than 12 years. The policy level for the recommendation about documenting recurrent throat infection was an option: (1) Clinicians may recommend tonsillectomy for recurrent throat infection with a frequency of at least 7 episodes in the past year, at least 5 episodes per year for 2 years, or at least 3 episodes per year for 3 years with documentation in the medical record for each episode of sore throat and ≥1 of the following: temperature >38.3°C (101°F), cervical adenopathy, tonsillar exudate, or positive test for group A beta-hemolytic streptococcus.

DIFFERENCES FROM PRIOR GUIDELINE

(1) Incorporating new evidence profiles to include the role of patient preferences, confidence in the evidence, differences of opinion, quality improvement opportunities, and any exclusion to which the action statement does not apply. (2) There were 1 new clinical practice guideline, 26 new systematic reviews, and 13 new randomized controlled trials included in the current guideline update. (3) Inclusion of 2 consumer advocates on the guideline update group. (4) Changes to 5 KASs from the original guideline: KAS 1 (Watchful waiting for recurrent throat infection), KAS 3 (Tonsillectomy for recurrent infection with modifying factors), KAS 4 (Tonsillectomy for obstructive sleep-disordered breathing), KAS 9 (Perioperative pain counseling), and KAS 10 (Perioperative antibiotics). (5) Seven new KASs: KAS 5 (Indications for polysomnography), KAS 6 (Additional recommendations for polysomnography), KAS 7 (Tonsillectomy for obstructive sleep apnea), KAS 12 (Inpatient monitoring for children after tonsillectomy), KAS 13 (Postoperative ibuprofen and acetaminophen), KAS 14 (Postoperative codeine), and KAS 15a (Outcome assessment for bleeding). (6) Addition of an algorithm outlining KASs. (7) Enhanced emphasis on patient and/or caregiver education and shared decision making.

Postoperative Nausea and Vomiting in Paediatric Anaesthesia

Postoperative nausea and vomiting (PONV) is a common complication in paediatric anaesthesia and is a source of significant morbidity. Various independent risk factors have been implicated in the development of paediatric PONV, including higher pain scores postoperatively, the use of opioids for pain management and the use of volatile anaesthetics for the maintenance of anaesthesia. This review of the current literature regarding the prevention and treatment of paediatric PONV is based on a search of the PubMed database, which identified published clinical trials, systematic reviews and meta-analyses. While the occurrence of PONV in many cases is difficult to avoid entirely, the risk can be mitigated by the use of multimodal nonopioid analgesic regimens, total intravenous drugs in favour of volatile anaesthetics and an appropriate regimen of prophylactic pharmacotherapy. Frequently administered drug classes for the prevention of PONV include corticosteroids, 5HT3 antagonists and anticholinergics. The clinical use of the findings in the literature may help to reduce the occurrence of PONV in children. In this review, we provide comprehensive and updated information on the risk factors contributing the occurrence of PONV in children, outline the current opinion on the drugs that are commonly used for management and provide an overview of the guidelines that are used to help establish the prophylaxis and treatment of paediatric PONV.

A Technology-Assisted, Brief Mind-Body Intervention to Improve the Waiting Room Experience for Chemotherapy Patients: Randomized Quality Improvement Study

Background

Patients waiting for chemotherapy can experience stress, anxiety, nausea, and pain. Acupressure and meditation have been shown to control such symptoms.

Objective

This study aimed to evaluate the feasibility and effectiveness of an integrative medicine app to educate patients about these self-care tools in chemotherapy waiting rooms.

Methods

We screened and enrolled cancer patients in chemotherapy waiting rooms at two Memorial Sloan Kettering Cancer Center locations. Patients were randomly assigned into an intervention arm in which subjects watched acupressure and meditation instructional videos or a control arm in which they watched a time- and attention-matched integrative oncology lecture video. Before and after watching the videos, we asked the patients to rate four key symptoms: stress, anxiety, nausea, and pain. We performed the analysis of covariance to detect differences between the two arms postintervention while controlling for baseline symptoms.

Results

A total of 223 patients were enrolled in the study: 113 patients were enrolled in the intervention arm and 110 patients were enrolled in the control arm. In both groups, patients showed significant reductions in stress and anxiety from baseline (all P<.05), with the treatment arm reporting greater stress and anxiety reduction than the control arm (1.64 vs 1.15 in stress reduction; P=.01 and 1.39 vs 0.78 in anxiety reduction; P=.002). The majority of patients reported that the videos helped them pass time and that they would watch the videos again.

Conclusions

An integrative medicine self-care app in the waiting room improved patients’ experiences and reduced anxiety and stress. Future research could focus on expanding this platform to other settings to improve patients’ overall treatment experiences.

Comparing Cold/Liquid Diet vs Regular Diet on Posttonsillectomy Pain and Bleeding

Objective Tonsillectomy is a common operation; however, there are controversial opinions regarding the posttonsillectomy diet. The aim of this study was to compare the effects of cold/liquid diet vs regular diet on posttonsillectomy pain and bleeding. Study Design Prospective randomized controlled trial. Setting Tertiary referral center. Subjects and Methods In total, 194 children who underwent tonsillectomy (with or without adenoidectomy) were randomly allocated into 2 groups. A total of 100 patients were allocated in the cold/liquid diet, and 94 patients were allocated in the regular diet group. Pain score was recorded for the first 7 days, and rate of hemorrhage was recorded for 10 days after surgery. Results The participants' age range was 3 to 17 years. The mean pain score level in the regular diet group after breakfast, lunch, and dinner was not statistically significant in comparison with the cold/liquid diet group. One patient in the regular diet group was admitted to the hospital due to secondary bleeding, but it stopped without any intervention. Conclusion Most otolaryngologists believe in dietary restrictions following tonsillectomy. However, there is much controversy regarding posttonsillectomy dietary advice in the literature. In addition, only a few randomized clinical trials have focused on this subject. We found that there was no difference between regular diet and cold/liquid diet in terms of posttonsillectomy pain and bleeding. Hence, we do not recommend a limited posttonsillectomy diet.

Influence of dietary and physical activity restriction on pediatric adenotonsillectomy postoperative care in Brazil: a randomized clinical trial

Introduction

Although culturally food and physical activity restriction are part of the routine postoperative care of many Brazilian surgeons, current evidences from other countries support no such recommendations.

Objective

To determine whether dietary and physical restriction effectively lead to a decrease on postoperative complications of adenotonsillectomy in children when compared to no restriction.

Methods

We have designed a randomized clinical trial comparing two intervention: no specific counseling on diet or activity (Group A), and restriction recommendations on diet and physical activities (Group B). Caregivers completed a questionnaire on observed pain, diet and activity patterns, and medications administered. Parameters were compared at the 3rd and at the 7th postoperative day between intervention groups.

Results

We have enrolled a total of 95 patients, 50 in Group A and 45 in Group B. Fourteen patients were lost to follow up. Eventually, 41 patients in group A and 40 in Group B were available for final analysis. Mean age in months (A = 79.5; SD = 33.9/B = 81.1; SD = 32.6) and sex (A = 58% male; B = 64.4% male) were equivalent between groups. Pain, evaluated through visual analog scale in the 3rd (A = 2.0; IQR 1–6/B = 4.5; IQR 2–6; p = 0.18) and in the 7th (A = 1.0; IQR 1.0–4.5/B = 2.0; IQR 1.0–4.7; p = 0.29) postoperative days, was not different between groups, as was the amount of analgesics administered. Dietary and physical activity patterns also showed no statistically significant differences between groups.

Conclusion

Dietary and activity restriction after adenotonsillectomy does not seem to affect patients’ recovery. Such information may impact considerably on the social aspects that involve a tonsillectomy, reducing the working days lost by parents and accelerating the return of children to school.

Assessment and management of pain in pediatric otolaryngology

INTRODUCTION

Pain is a disease by itself and it's a public health concern of major implication in children, not just because of the emotional component of the child and his family, but also due to the potential morbidity and mortality involving it. A proper assessment of pain it's a challenge in the pediatric population, due to their lack of understanding and verbalization of hurt. Additionally, a satisfactory treatment of pediatric pain can be arduous due to a lack of clinical knowledge, insufficient pediatric research, and the fear to opioid side effects and addiction.

OBJECTIVES

The aim of this review is to address the current definitions of pain, its physiological mechanisms and the consequences of its inadequate management, as well as, to guide the clinicians in the assessment and management of pain in the pediatric population at otolaryngology services.

METHODOLOGY

Narrative review by selective MeSH search terms: Children, Pediatrics, Otolaryngology, Pain measurement, Pain Management, Analgesics and Analgesia, from databases: MEDLINE/PubMed, Cochrane, ISI, Current Contents, Scielo and LILACS, between January 2000 and May 2016.

RESULTS

129 articles were reviewed according to the requirements of the objectives. Pain measurement is a challenge in children as there are no physical signs that constitute an absolute or specific indicator of pain, and its diagnosis must rely on physiological, behavioral and self-report methods. Regarding treatment, a suitable alternative are the non-pharmacological cognitive/behavioral therapies helped by pharmacological therapies tailored to the severity of pain and the child's age. We provide evidence-based recommendations on pain treatment, including non-opioid analgesics, opioid analgesics and adjuvant medicines to improve the management of pain in children in otolaryngology services.

CONCLUSIONS

We present a global review about assessment and management of pain in pediatric otolaryngology, which leads to future specific reviews on each topic. Research gaps on pain assessment and pharmacological interventions in neonates, infants and children are very wide and it should be promoted ethical and safe research on pain control in this population.

Nursing process in post tonsillectomy pain diagnosis: a systematic review

Objective:

Tonsillectomy is the most common surgery in the field of ENT. Pain is the most common post tonsillectomy complaint. Considering the importance of nursing cares in relieving post-surgery pain in general and post-tonsillectomy pain in particular, this study is conducted with the aim of presenting nursing process in post tonsillectomy pain diagnosis for decreasing loss of appropriate opportunities in nursing cares and achieving appropriate results in taking care of the patients.

Methods:

This study is a targeted systematic review focusing on “effective nursing measures in relieving children’s post tonsillectomy pain”. The main stages of searching strategy included searching in electronic sources of Latin databases; Pub Med, Science Direct, and EMBASE and Persian databases; SID, Iran medex, ISC to find published articles from 2009 to 2014. In the end, final synthesis was done on eight articles in English.

Findings:

Effective nursing measurements for relieving post tonsillectomy pain include: decreasing children’s anxiety through children and their families’ psychological preparation by nurses and other caregivers, using cold compress to reduce neck and jaw pain, presenting distraction techniques, offering fluids and cold foods immediately in the period after surgery, creating a comfortable environment for the children, avoiding too much of talking and adequate sleep.

Conclusion:

It is recommended to the nursing managers and nurses to perform cares achieved from this systematic review to achieve appropriate results in relieving post tonsillectomy pain.

Nurses' provision of parental guidance regarding school-aged children's postoperative pain management: a descriptive correlational study

Involving parents in children's pain management is essential to achieve optimal outcomes. Parents need to be equipped with sufficient knowledge and information. Only a limited number of studies have explored nurses' provision of parental guidance regarding the use of nonpharmacologic methods in children's pain management. This study aimed to examine nurses' perceptions of providing preparatory information and nonpharmacologic methods to parents, and how their demographics and perceived knowledge adequacy of these methods influence this guidance. A descriptive correlational study using questionnaire surveys was conducted to collect data from a convenience sample of 134 registered nurses working in seven pediatric wards of two public hospitals in Singapore. Descriptive statistics, independent-samples t test, and multiple linear regression were used to analyze the data. Most nurses provided various types of cognitive information to parents related to their children's surgery, whereas information about children's feelings was less often provided. Most nurses provided guidance to parents on positioning, breathing technique, comforting/reassurance, helping with activities of daily living, relaxation, and creating a comfortable environment. Nurses' provision of parental guidance on preparatory information and nonpharmacologic methods was significantly different between subgroups of age, education, parent or not, and perceived knowledge adequacy of nonpharmacologic methods. Nurses' perceived knowledge adequacy was the main factor influencing their provision of parental guidance. More attention should be paid to nurses who are younger, have less working experience, and are not parents. There is a need to educate nurses about nonpharmacologic pain relief methods to optimize their provision of parental guidance.

Is fasting duration important in post adenotonsillectomy feeding time?

Background:

Adenotonsillectomy is a common otolaryngology surgery. Nausea and vomiting are the most common complications of this procedure with a prevalence ranging from 49% to 73 %.

Objectives:

Our aim was to evaluate the effects of short time fasting protocol on decreasing postoperative pain, nausea and vomiting, and initiation of oral feeding after adenotonsillectomy.

Patients and Methods:

120 children aged 4 to 14 years candidates for adenotonsillectomy were randomly divided into intervention and control groups (n = 120, 60 in each group). Each patient of the intervention group was given oral dextrose 10% as much volume as he could consume at 3 and 6 hours prior to the operation. All the data including pain severity, nausea and vomiting of the patients, the time of oral feeding initiation etc. were gathered in checklists after the operation. Statistical analyses were then performed using Statistical Package for the Social Sciences (SPSS) software version 16. Descriptive statistical methods and mean difference test for independent groups and chi square test or Fisher exact test, and if regression needed model test were applied. A P value of 0.05 or less was considered statistically significant.

Results:

The amount of Acetaminophen administered for the intervention group was significantly lower than the control group, and also the time of oral feeding initiation was significantly shorter in the intervention group than the control group (P < 0.005). Pain severity at all occasions following surgery was significantly lower in the intervention group than the control group (P < 0.001). Although frequency of nausea at recovery time was significantly lower in the intervention group than the control group (P < 0.002), there were no significant differences in frequency of nausea between the two groups at other postoperative occasions. Postoperative vomiting frequency was not significant between the two groups at any occasions.

Conclusions:

The findings of this survey showed that shortening the duration of pre-adenotonsillectomy fasting period and hydration of patients several hours prior to the operation might be effective in decreasing postoperative pain and facilitating postoperative oral feeding initiation. Nevertheless this method does not seem to prevent postoperative nausea and vomiting.

Pain management for pediatric tonsillectomy: an integrative review through the perioperative and home experience

PURPOSE

This integrative review aims to increase our understanding of current pain management care practices for children undergoing tonsillectomy.

CONCLUSIONS

Synthesis of the literature resulted in four main opportunities for care providers to manage pain: preoperative education and preparation, intraoperative surgical interventions, and postoperative pharmacologic and nonpharmacologic interventions in the post anesthesia care unit and home settings.

PRACTICE IMPLICATIONS

Nurses have many opportunities to understand pain management practices and intervene to minimize pain experienced in pediatric outpatients undergoing tonsillectomy.

The quality of the face-to-face counselling in paediatric ambulatory tonsillectomy: parental point of view

The objective of this study was to examine parental opinion on the quality of preoperative face-to-face counselling about the child's preoperative fasting. Families, whose child was admitted for ambulatory tonsillectomy were randomly assigned to the study groups (n = 116; 58/58). The intervention group received the information with face-to-face counselling, and the control group in written form. The parents assessed (visual analogue scale) the level of clarity, intelligibility and adequacy of the information, how well they had understood the meaning and the implementation of the child's preoperative fast, as well as their own skills and success to implement the child's fast. The parents in the intervention group felt that the information was significantly clearer, more intelligible and adequate and that they succeeded well. Face-to-face counselling is an effective way to educate the parents.

Tonsillectomy care for the pediatrician

Pediatricians play an important role in the perioperative care of hospitalized children after tonsillectomy and are often called upon to manage posttonsillectomy problems in the outpatient setting. The tonsillectomy operation has changed in recent years. More children are operated upon for sleep disordered breathing and fewer for recurrent pharyngitis. New instruments now permit less invasive surgery. Systematic reviews by the Cochrane Collaboration and others have helped define best practices for preoperative assessment and postoperative care. This article will outline these practices as defined in the 2011 American Academy of Otolaryngology-Head and Neck Surgery Foundation clinical practice guideline "Tonsillectomy in Children." It will describe the different tonsillectomy operations, discuss patterns of normal healing, and review management of pain and posttonsillectomy hemorrhage to form a foundation for improved pediatric care.

Management of adverse side-effects after chemotherapy in macaques as exemplified by streptozotocin: case studies and recommendations

The chemotherapeutic streptozotocin is used for induction of diabetes in animal models including non-human primates. Being a cytotoxic nitrosourea compound, it can be associated with adverse events (AEs), mainly nausea and emesis, nephrotoxicity, elevated liver transaminase levels, pulmonary oedema and, most prominently, metabolic acidosis: these can be severe in some cases. The incidence and gravity are to some extent related to the characteristics of the individual animal, diagnostic tools, prompt recognition of symptoms and supportive measures. Careful animal selection, dose adaptation and supportive actions such as renal protective hydration are the main tools in managing AEs, but do not fully eliminate unavoidable and sometimes life-threatening conditions. In our centre we have built experience in a cohort of 78 cynomolgus and rhesus macaques in which six cases manifested severe AEs (8%). This experience has prompted implementation of strategies for early detection and management of adverse effects, together with an animal refinement programme. We present here specific pretreatment regimens, post-infusion laboratory evaluations, and flow charts to assess/treat metabolic acidosis and precipitating factors. Case reports of the six animals with severe AEs are presented to illustrate management of AEs, especially metabolic acidosis, and criteria for early euthanasia where appropriate. We conclude that improved monitoring and validated tools allow for optimal management of adverse effects in an early stage of their manifestation. Reduced morbidity and mortality not only improve individual animal wellbeing but also avoid model-induced confounding that diminishes the translational value of the experimental protocol.

Correlation between acoustic rhinometry and visual analogue scale in children with no nasal symptoms: a prospective cohort study

OBJECTIVES

Acoustic rhinometry is an objective tool to evaluate nasal obstruction. The aim of this study was to evaluate the usefulness of visual analogue scale (VAS) as a subjective tool for nasal obstruction and the correlation between acoustic rhinometry and VAS in children with no nasal symptoms.

DESIGN

Unilateral acoustic values and VAS were measured at baseline and after decongestion of the nose.

SETTING

Tertiary academic hospital.

PARTICIPANTS

The study included 124 children aged between 7 and 14 years with no permanent nasal symptoms.

RESULTS

At baseline, the mean minimal cross-sectional area on the right side was 0.392 cm(2) (sd 0.094), and on the left side 0.360 cm(2) (sd 0.093), whereas the mean VAS on the right side was 7.43 (sd 2.50) and on the left side 6.81 (sd 3.01). After decongestion, the mean minimal cross-sectional area on the right and left sides were 0.421 cm(2) (sd 0.087) and 0.373 cm(2) (sd 0.11), respectively, whereas the mean VAS on the right and left sides were 8.77 (sd 2.02) and 8.54 (sd 2.14), respectively. At baseline, a significant correlation was found between VAS and minimal cross-sectional area, but no correlation was found between VAS and acoustic values after decongestion.

CONCLUSIONS

We conclude that VAS shows potential as a subjective tool to investigate nasal obstruction in children over 7 years of age. There was a correlation between VAS and acoustic rhinometry in children with no nasal symptoms at baseline. No correlation was found in children with decongested normal nasal airways.

Are randomised controlled trials involving adenotonsillectomy well reported?

INTRODUCTION

Evidence-based medicine guides clinical practice. Currently, the evidence base on adenotonsillectomy is under scrutiny to establish clinical guidelines. It is therefore important that reports of clinical trials are of high quality. Guidance on reporting of randomised controlled trials (RCTs) are available in the Consolidated Standards for Reporting Trials (CONSORT) statement first published in 1996 and revised in 2001 and 2010.

METHODS

A review of randomised controlled trials on adenotonsillectomy published after 2001 was undertaken. Each report was systematically assessed using the checklist of items from the CONSORT statement.

RESULTS

Twenty-five trials were identified. All trials, except one, were identified as a randomised controlled trial by title or abstract. Twenty percent of trials reported a sample size calculation. A third of trials reported their method of generating a random allocation sequence. Similarly, a third stated the method of implementing the random allocation. A fifth of trials reported a clear flow of trial participants, with only a single trial reporting this with the aid of a diagram.

CONCLUSION

This review shows the quality of reporting needs to be improved. Critical appraisal of poorly reported trials may result in erroneous conclusions, even though these trials may have been carried out with rigorous adherence to a protocol of high standard. Authors of clinical trial reports should be encouraged to consult the CONSORT statement.

Clinical practice guideline: tonsillectomy in children

OBJECTIVE

Tonsillectomy is one of the most common surgical procedures in the United States, with more than 530,000 procedures performed annually in children younger than 15 years. Tonsillectomy is defined as a surgical procedure performed with or without adenoidectomy that completely removes the tonsil including its capsule by dissecting the peritonsillar space between the tonsil capsule and the muscular wall. Depending on the context in which it is used, it may indicate tonsillectomy with adenoidectomy, especially in relation to sleep-disordered breathing. This guideline provides evidence-based recommendations on the preoperative, intraoperative, and postoperative care and management of children 1 to 18 years old under consideration for tonsillectomy. In addition, this guideline is intended for all clinicians in any setting who interact with children 1 to 18 years of age who may be candidates for tonsillectomy.

PURPOSE

The primary purpose of this guideline is to provide clinicians with evidence-based guidance in identifying children who are the best candidates for tonsillectomy. Secondary objectives are to optimize the perioperative management of children undergoing tonsillectomy, emphasize the need for evaluation and intervention in special populations, improve counseling and education of families of children who are considering tonsillectomy for their child, highlight the management options for patients with modifying factors, and reduce inappropriate or unnecessary variations in care.

RESULTS

The panel made a strong recommendation that clinicians should administer a single, intraoperative dose of intravenous dexamethasone to children undergoing tonsillectomy. The panel made a strong recommendation against clinicians routinely administering or prescribing perioperative antibiotics to children undergoing tonsillectomy. The panel made recommendations for (1) watchful waiting for recurrent throat infection if there have been fewer than 7 episodes in the past year or fewer than 5 episodes per year in the past 2 years or fewer than 3 episodes per year in the past 3 years; (2) assessing the child with recurrent throat infection who does not meet criteria in statement 2 for modifying factors that may nonetheless favor tonsillectomy, which may include but are not limited to multiple antibiotic allergy/intolerance, periodic fever, aphthous stomatitis, pharyngitis and adenitis, or history of peritonsillar abscess; (3) asking caregivers of children with sleep-disordered breathing and tonsil hypertrophy about comorbid conditions that might improve after tonsillectomy, including growth retardation, poor school performance, enuresis, and behavioral problems; (4) counseling caregivers about tonsillectomy as a means to improve health in children with abnormal polysomnography who also have tonsil hypertrophy and sleep-disordered breathing; (5) counseling caregivers that sleep-disordered breathing may persist or recur after tonsillectomy and may require further management; (6) advocating for pain management after tonsillectomy and educating caregivers about the importance of managing and reassessing pain; and (7) clinicians who perform tonsillectomy should determine their rate of primary and secondary posttonsillectomy hemorrhage at least annually. The panel offered options to recommend tonsillectomy for recurrent throat infection with a frequency of at least 7 episodes in the past year or at least 5 episodes per year for 2 years or at least 3 episodes per year for 3 years with documentation in the medical record for each episode of sore throat and 1 or more of the following: temperature >38.3°C, cervical adenopathy, tonsillar exudate, or positive test for group A β-hemolytic streptococcus.

Perioperative acupuncture and postoperative acupressure can prevent postoperative vomiting following paediatric tonsillectomy or adenoidectomy: a pragmatic randomised controlled trial

OBJECTIVE

To investigate the effectiveness of acupuncture and acupressure as supplements to standard treatment for postoperative vomiting in children undergoing tonsillectomy and/or adenoidectomy.

METHODS

A pragmatic, open, block-randomised controlled trial. The results were analysed according to the intention-to-treat principle. The study was conducted without extra resources in a normal setting at the day-surgery department of Lovisenberg Diakonale Hospital in Oslo. 154 children with an American Society of Anesthesiologists grade 1-2, weighing at least 10 kg, were included. Children with concomitant gastrointestinal diseases, emesis or antiemetic treatment <24 h preoperatively, rash or local infection over the actual acupuncture points were excluded together with patients whose parents' informed consent could not be obtained. The intervention group received acupuncture at pericardium 6 bilaterally, at a depth of approximately 0.7 cm with a median of 21 min during anaesthesia, followed by acupressure wristbands for 24 h and standard treatment. The control group received standard treatment. The primary end point was the occurrence of vomiting or retching during 24 h postoperatively.

RESULTS

Children in the acustimulation group experienced less retching and vomiting than the control group-46.8% versus 66.2% (p=0.015). The effect of acustimulation was specifically pronounced in girls and children aged 1-3 years.

CONCLUSION

This trial indicates the effectiveness of acustimulation as an adjunct to standard treatment. The results should encourage and promote the implementation of acustimulation for postoperative vomiting in children undergoing adenoidectomy or tonsillectomy.

The effect of preoperative nutritional face-to-face counseling about child's fasting on parental knowledge, preoperative need-for-information, and anxiety, in pediatric ambulatory tonsillectomy

OBJECTIVE

The objective of this study was to define how preoperative nutritional face-to-face counseling on child's fasting affects parental knowledge, preoperative need-for-information, and anxiety, in pediatric ambulatory tonsillectomy.

METHODS

The participants in the prospective, randomly allocated study were parents (intervention 62/control 62) with children (4-10 years) admitted for ambulatory tonsillectomy. Data were collected by the knowledge test designed for the study and with The Amsterdam preoperative anxiety and information scale (APAIS). The intervention group was invited to a preoperative visit to receive written and verbal face-to-face counseling. They were initiated into the child's active preoperative nutrition. The parents of the control group received current information without face-to-face counseling.

RESULTS

The parents followed the instructions. Their knowledge about the child's fast increased (p=0.003), and need-for-information and anxiety decreased (p<0.0001) significantly.

CONCLUSION

The preoperative face-to-face counseling with written information improves parental knowledge about the child's fasting and active preoperative nutrition, and relieves their need-for-information and anxiety.

PRACTICE IMPLICATIONS

The primary responsibility remains with the health care professionals when the active preoperative nutrition of the child and counseling on it are introduced into nursing practice.

Do diet and activity restrictions influence recovery after adenoidectomy and partial tonsillectomy?

OBJECTIVE

To determine if restrictions of postoperative diet concerning hard food and hot drinks as well as excessive physical exertion influence recovery during 14 days after T&A surgery.

METHODS

800 patients aged 3-13 years (median 6) underwent curette adenoidectomy with or without scissors tonsillotomy. 413 adenoidectomies and 387 adenotonsillotomies were performed. Caregivers of the children completed a questionnaire reporting their child's postoperative activity, diet, pain level, peak and duration, episodes of nausea and fever, medication and caregivers' satisfaction scores. The children were enrolled to food and effort restricted (FER), food non-restricted (FnR), effort non-restricted (EnR), and food and effort non-restricted (FEnR) groups at the end of follow-up.

RESULTS

Two hemorrhages requiring repeat surgery under general anesthesia in FER group and 42 mild episodes of spontaneously subsiding bleeding from nose or mouth occurred. More than one episodes of hemorrhage were observed in other 8 individuals (total incidence of hemorrhages 9.7%). No hemorrhages were noted in the FEnR and FnR groups. There were 23 (4.4%) participants with episodes of bleeding, among them 21 mild hemorrhages, in the FER group and 21 (12.0%) in the EnR group (p<0.001). Peak pain level was lowest in FEnR group (p<0.001) and indications for antibiotics most frequent in FnR group (p<0.001). Parental satisfaction level was highest in FnR and FEnR groups (p<0.001).

CONCLUSIONS

The majority of caregivers reported care of children after T&A surgery according to the instructions. Most frequently disobeyed instructions were those concerning physical exertion. Diet and activity restrictions seem to influence postoperative recovery. Parental satisfaction scores were highest in non-restricted groups.
