Invasive procedures and atraumatic care in pediatric nursing practice: nurses' perceptions

Introduction

Invasive procedures in pediatric nursing practice require a child-centered approach to minimize pain levels associated with manifestations of stress, anxiety, and long-term traumatic reactions.

Method

This cross-sectional study aimed at identifying nurses' perception of stress, anxiety, and pain levels in children and adolescents (0-18 years) undergoing invasive procedures, and strategies used to minimize the associated distress. Based on a literature review, an online questionnaire was developed that evaluates the distress associated with frequent invasive procedures and strategies used to reduce discomfort.

Results

Participants were 157 nurses who provided nursing care to children in all types of healthcare settings, such as hospitals and community health centers. Nurses evaluated lumbar puncture and catheter insertion as the procedures that caused more stress, anxiety, and pain in all age groups. ANOVA and post-hoc analyses indicate that nurses perceived adolescents as experiencing less stress than children in all the invasive procedures. Pediatric specialist nurses perceived a significantly higher total level of distress (an index that indicates stress, anxiety or pain in the whole group of procedures) compared to nurses with other specialties or generalist nurses, in all age groups. Non-pharmacological strategies were the most frequently used strategies used by nurses for minimizing distress in children, including distraction (51.2%), preparation (30.7%), and sensory techniques (14.6%). Pharmacological strategies, such as topical anesthetics and light sedation, were less frequently used.

Conclusion

This study highlights the importance of specialized training and knowledge concerning strategies to reduce distress in pediatric invasive procedures, suggesting the need for more significant investment in education and support for nursing professionals to improve patient experience.

The nurse's role in assisting with a lumbar puncture in an infant or child

A lumbar puncture may be performed for various reasons, but is commonly used to facilitate the diagnosis of central nervous system infections in infants and children. It involves inserting a needle into the lower spine to obtain cerebrospinal fluid, which is then sent for testing in a laboratory. The results of the tests, together with a clinical assessment of a patient, can guide the effective treatment of infections and reduce the risk of neurological conditions. This article outlines some of the reasons why lumbar punctures are performed, discusses the practical aspects of the procedure and explains how nurses can effectively support the child and their family, while also assisting the practitioner undertaking the procedure.

Hypnosis and nitrous oxide impact on the school aged patients' anxiety and cooperation candidate for tooth extraction: A randomized clinical trial

Background

This randomized clinical trial (RCT) investigated whether hypnosis would lead to favorable outcomes in reducing anxiety, enhancing cooperation, and improving physiological responses in school-aged children undergoing tooth extraction compared to nitrous oxide/oxygen (N2O/O2) and conventional behavior guidance (CBG).

Methods

Sixty-six school-aged children (mean age: 7.87 ± 1.18 years) who needed one posterior primary tooth extraction were included. Children with low-to-moderate anxiety were randomly divided into three groups (n = 22 each): hypnosis, N2O/O2, and CBG. Anxiety levels during and after anesthetic injection and tooth extraction were assessed using the Venham Clinical Anxiety Scale (VCAS) and the Venham Picture Test (VPT). Changes in heart rate (HR) and oxygen saturation (SpO2) were monitored. Children's cooperation levels were measured using the Venham Clinical Cooperation Scale (VCCS).

Results

The VPT scores were significantly higher in the CBG group than in the N2O/O2 and hypnosis groups (p < 0.001). The VCAS scores in the N2O/O2 group were lower than those in the CBG group (p < 0.05) and were comparable to those in the hypnosis group. The VCCS scores were significantly higher in the CBG group than in the N2O/O2 and hypnosis groups (p < 0.05). HR changes in the N2O/O2 group were significantly lower than in the hypnosis and CBG groups (p < 0.05). No significant difference in pain was observed between the groups the day after the intervention.

Conclusion

N2O/O2 inhalation and hypnosis are effective in reducing self-reported and observed anxiety and improving cooperation levels in pediatric patients during dental extraction. Moreover, the frequency of reported pain was lower in the hypnosis group compared to the other groups.

Peri-operative cardiac arrest in children as reported to the 7th National Audit Project of the Royal College of Anaesthetists

The 7th National Audit Project of the Royal College of Anaesthetists studied peri-operative cardiac arrest. An activity survey estimated UK paediatric anaesthesia annual caseload as 390,000 cases, 14% of the UK total. Paediatric peri-operative cardiac arrests accounted for 104 (12%) reports giving an incidence of 3 in 10,000 anaesthetics (95%CI 2.2-3.3 per 10,000). The incidence of peri-operative cardiac arrest was highest in neonates (27, 26%), infants (36, 35%) and children with congenital heart disease (44, 42%) and most reports were from tertiary centres (88, 85%). Frequent precipitants of cardiac arrest in non-cardiac surgery included: severe hypoxaemia (20, 22%); bradycardia (10, 11%); and major haemorrhage (9, 8%). Cardiac tamponade and isolated severe hypotension featured prominently as causes of cardiac arrest in children undergoing cardiac surgery or cardiological procedures. Themes identified at review included: inappropriate choices and doses of anaesthetic drugs for intravenous induction; bradycardias associated with high concentrations of volatile anaesthetic agent or airway manipulation; use of atropine in the place of adrenaline; and inadequate monitoring. Overall quality of care was judged by the panel to be good in 64 (62%) cases, which compares favourably with adults (371, 52%). The study provides insight into paediatric anaesthetic practice, complications and peri-operative cardiac arrest.

Longitudinal Study on Dental Status, Caries Risk Assessment, and Oral Health-Related Quality of Life in 3-6-Year-Old Children Receiving Nitrous Oxide Inhalational Sedation

Introduction Dental caries prevention in early childhood is crucial, necessitating timely assessments by dental professionals and parents. The oral health of children during their early years can significantly impact both the children themselves and their parents' quality of life. This study seeks to assess the changes in oral health-related quality of life after treatment under nitrous oxide sedation in anxious preschool children, for whom treatment otherwise is quite difficult chairside. Aim The aim of this study is to assess the association between dental caries status, risk assessment, and oral health-related quality of life (OHRQoL) in 3-6-year-old children, before and after undergoing treatment under nitrous oxide inhalation sedation. Materials and methods Eighty children were assessed for caries risk and dental status using the caries risk assessment for treatment (CRAFT) tool. Nitrous oxide sedation was employed for dental treatment, and assessments were conducted pre-treatment and post-treatment. Statistical analyses performed were paired t-tests, correlation analyses, and Chi-Square tests. Results The study revealed a mean age of 4.033 ± 0.96, with a balanced gender distribution (47.5% boys, 52.5% girls). Post-treatment, significant negative correlations were observed between OHRQoL and treatment outcomes, emphasizing improved oral health-related quality of life. Associations were found between OHRQoL, pufa index, and caries risk post-treatment. Conclusion The current research suggests that treatment done under nitrous oxide sedation could improve the OHRQoL in preschool children. Integrating risk assessment and OHRQoL enhances understanding, facilitating targeted prevention and treatment strategies. Addressing untreated dental caries is imperative for optimizing the overall well-being of children in this age group.

The application of drug behavior management methods in the treatment of dental fear and oral diseases in children: A review

Oral behavior management methods include basic behavior management methods and drug behavior management methods. In many cases, dental treatment that cannot be done simply through basic behavior management is not possible. The uncooperative behavior of children with dental fear in oral treatment has increased the demand for medication based behavior management methods. Drug sedation can provide more effective analgesic and anti-anxiety effects, thereby helping to provide comfortable, efficient, and high-quality dental services. This article will review the drug sedation methods selected in clinical treatment of pediatric dental fear in recent years, as well as the safety and effectiveness of commonly used drugs, in order to provide guidance for dental professionals in clinical practice.

[Inhalation anesthesia in the cat: Development of cuff pressure when using nitrous oxide]

OBJECTIVE

During inhalation anesthesia with nitrous oxide in oxygen the pressure in the cuff of the endotracheal tube may increase due to diffusion of nitrous oxide into the cuff. The aim of the study was to investigate the development of cuff pressure during nitrous oxide anesthesia under clinical conditions in feline patients and to identify possible influencing factors such as tube size and gas flow rate.

MATERIAL AND METHODS

The prospective study included cats scheduled for inhalation anesthesia with nitrous oxide for a minimum duration of 60 minutes at the Department for Small Animals of the University of Leipzig. Cuff pressure was adjusted with a cuff manometer and its development was recorded.

RESULTS

In total, the cuff pressure values of 24 cats were recorded. Animals were allocated into groups by tube size (ID 4.0 mm and ID 4.5 mm) and by fresh gas flow rate: low flow rate (0.6 l/min) and high flow rate (3 l/min). During anesthesia, cuff pressure increased over time, with statistical significance occurring from 45 minutes onwards in comparison to the initial cuff pressure (p=0.005). After 60 minutes, there was a mean cuff pressure increase of 3 cmH2O. Despite this moderate mean increase, highly variable pressure values up to 48 cmH2O in individual animals were recorded. No cat reached the termination criterion of 60 cmH2O cuff pressure. Effects of tube size (p=0.63) and flow rate (p=0.334) on the cuff pressure were not evident.

CONCLUSION

After a period of 45 minutes of nitrous oxide administration, a significant increase in cuff pressure occurs in the cat. However, tube size and total gas flow rate do not seem to influence the cuff pressure development.

CLINICAL RELEVANCE

When using nitrous oxide during inhalation anesthesia, regular cuff pressure evaluation and correction are necessary and hence recommended in feline patients. As individual pressure changes may be highly variable, no fixed recommendations for optimal management are possible.

Predictors of Parental Acceptance towards Contemporary Behavior Management Techniques Used in Pediatric Dentistry: A Preliminary Study on Turkish Population

BACKGROUND

Parents, who make the final decision regarding their child's treatment, play a significant role in their dental care. Parental approval is important for each stage of treatment and may affect the physician's approach to the treatment. Therefore, it is essential for pediatric dentists to comprehend which behavior management techniques (BMTs) are acceptable to parents and to identify the factors that influence their acceptability.

METHODS

Parents who were bringing their children for dental treatment answered a survey on the acceptance of twenty contemporary BMTs. The sociodemographic data of the parents and the age, gender, and Frankl behavior rating scale (Frankl) scores of their children were recorded. Parents were asked to indicate their level of acceptance of each BMT. Binary logistic regression analysis was designed to see the predictors of "accepted" and "declined" answers.

RESULTS

According to acceptance frequencies, the most accepted technique was communication and communicative guidance. The most declined technique was parental absence. The child's age, gender, Frankl score, parental educational status, and parent type predict the acceptability of some BMTs.

CONCLUSION

This study revealed that pediatric dentists must consider parent and child factors when selecting BMTs for children. We believe that this study can provide a basis for determining which factors pediatric dentists should consider when selecting individualized BMTs.

Pain Management in Children Admitted to the Emergency Room: A Narrative Review

Pain is a biopsychosocial experience characterized by sensory, physiological, cognitive, affective, and behavioral components. Both acute and chronic pain can have short and long-term negative effects. Unfortunately, pain treatment is often inadequate. Guidelines and recommendations for a rational approach to pediatric pain frequently differ, and this may be one of the most important reasons for the poor attention frequently paid to pain treatment in children. This narrative review discusses the present knowledge in this regard. A literature review conducted on papers produced over the last 8 years showed that although in recent years, compared to the past, much progress has been made in the treatment of pain in the context of the pediatric emergency room, there is still a lot to do. There is a need to create guidelines that outline standardized and easy-to-follow pathways for pain recognition and management, which are also flexible enough to take into account differences in different contexts both in terms of drug availability and education of staff as well as of the different complexities of patients. It is essential to guarantee an approach to pain that is as uniform as possible among the pediatric population that limits, as much as possible, the inequalities related to ethnicity and language barriers.

Sedative and adverse effect comparison between oral midazolam and nitrous oxide inhalation in tooth extraction: a meta-analysis

OBJECTIVE

Oral midazolam and nitrous oxide inhalation were commonly used sedative and analgesic techniques during tooth extraction. It is still controversial whether oral midazolam can replace the nitrous oxide inhalation for sedative and analgesic treatment of tooth extraction. Therefore, we conducted this study in order to provide a reference for doctors to choose effective sedative and analgesic treatment in tooth extraction.

METHODS

We searched the Chinese and English databases including PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure, Wanfang and VIP information databases.

RESULTS

Through this meta-analysis, we found that the success rate of sedation and analgesia treatment with oral midazolam during tooth extraction was 75.67% and the incidence of adverse reactions was 21.74%. The success rate of sedation and analgesia treatment using nitrous oxide inhalation during tooth extraction was 93.6% and the incidence of adverse reactions was 3.95%.

CONCLUSION

The use of nitrous oxide inhalation for sedation and analgesia during tooth extraction is very effective, and oral midazolam can be used as an alternative to nitrous oxide inhalation.

Evaluation and Treatment of Pain in Fetuses, Neonates and Children

The perception of pain is individual and differs between children and adults. The structures required to feel pain are developed at 24 weeks of gestation. However, pain assessment is complicated, especially in neonates, infants and preschool-age children. Clinical scales adapted to age are the most used methods for assessing and monitoring the degree of pain in children. They evaluate several behavioral and/or physiological parameters related to pain. Some monitors detect the physiological changes that occur in association with painful stimuli, but they do not yet have a clear clinical use. Multimodal analgesia is recommended for pain treatment with non-pharmacological and pharmacological interventions. It is necessary to establish pharmacotherapeutic protocols for analgesia adjusted to the acute or chronic, type and intensity of pain, as well as age. The most used analgesics in children are paracetamol, ibuprofen, dipyrone, opioids (morphine and fentanyl) and local anesthetics. Patient-controlled analgesia is an adequate alternative for adolescent and older children in specific situations, such as after surgery. In patients with severe or persistent pain, it is very important to consult with specific pain services.
