Effectiveness of technology-based interventions compared with other non-pharmacological interventions for relieving procedural pain in hospitalized neonates: a systematic review

OBJECTIVE

The objective of this review was to evaluate the effectiveness of technology-based interventions for relieving procedural pain among hospitalized neonates compared with other non-pharmacological interventions.

INTRODUCTION

Neonates who require hospital care often experience acute pain during medical procedures. The current best practice for relieving pain in neonates is the use of non-pharmacological interventions, such as oral solutions or intervention-based human touch. Technological solutions (eg, games, eHealth applications, mechanical vibrators) have become more commonplace in pediatric pain management over recent years; however, there is a sizeable knowledge gap around how effective technology-based interventions are for relieving pain in neonates.

INCLUSION CRITERIA

This review considered experimental trials that include technology-based, non-pharmacological interventions for relieving procedural pain among hospitalized neonates. The primary outcomes of interest include pain response to a procedure measured by a pain assessment scale validated for neonates, behavioral indicators, and changes in physiological indicators.

METHODS

The search strategy aimed to identify both published and unpublished studies. MEDLINE (PubMed), CINAHL (EBSCOhost), Scopus, Cochrane Central Register of Controlled Trials, MedNar, and EBSCO Open Dissertations databases were searched for studies published in English, Finnish, or Swedish. Critical appraisal and data extraction were conducted by 2 independent researchers who adhered to JBI methodology. Meta-analysis could not be performed due to considerable heterogeneity in the studies; as a result, the findings are presented narratively.

RESULTS

A total of 10 randomized controlled trials involving 618 children were included in the review. The staff members delivering the interventions and the outcome assessors were not blinded in all of the studies, which introduced a potential risk of bias. The presented technology-based interventions were diverse, including laser acupuncture, noninvasive electrical stimulation of acupuncture points, robot platform, vibratory stimulation, recorded maternal voice, and recorded intrauterine voice. In the studies, pain was measured using validated pain scales, behavioral indicators, and physiological variables. In the studies in which pain was assessed with a validated pain measure (N=8), technology-based pain relief was significantly more effective than the comparator in 2 studies, whereas no statistically significant differences were observed in 4 studies and the technology-based intervention was less effective than the comparator in 2 studies.

CONCLUSIONS

The effectiveness of technology-based interventions in relieving neonatal pain, either as a standalone method or in combination with another non-pharmacological method, was mixed. Further research is needed to provide reliable evidence on which technology-based, non-pharmacological pain relief intervention is most effective for hospitalized neonates.

Clinical Hypnosis for Procedural Pain and Distress in Children: A Scoping Review

OBJECTIVE

Pain and distress are common in children undergoing medical procedures, exposing them to acute and chronic biopsychosocial impairments if inadequately treated. Clinical hypnosis has emerged as a potentially beneficial treatment for children's procedural pain and distress due to evidence of effectiveness and potential superiority to other psychological interventions. However, systematic reviews of clinical hypnosis for children's procedural pain and distress have been predominantly conducted in children undergoing oncology and needle procedures and are lacking in broader pediatric contexts. This scoping review maps the evidence of clinical hypnosis for children's procedural pain and distress across broad pediatric contexts while highlighting knowledge gaps and areas requiring further investigation.

METHODS

Published databases (PubMed, Cochrane Library, PsycINFO, Embase, CINAHL, Scopus, and Web of Science) and grey literature were searched in addition to hand-searching reference lists and key journals (up to May 2022). Two independent reviewers screened the titles and abstracts of search results followed by a full-text review against eligibility criteria. Articles were included if they involved a clinical hypnosis intervention comprising an induction followed by therapeutic suggestions for pain and distress in children undergoing medical procedures. This review followed the Arksey and O'Malley (2005) methodology and incorporated additional scoping review recommendations by the Joanna Briggs Institute and Preferred Reporting Items for Systematic Reviews and Meta-Analyses.

RESULTS

A total of 38 eligible studies involving 2,205 children were included after 4,775 articles were screened. Research on clinical hypnosis for children's procedural pain and distress was marked by a lack of fidelity measures and qualitative data as well as by inadequate intervention reporting and high attrition rates. Evidence regarding the safety of clinical hypnosis, pain unpleasantness outcomes, factors influencing outcomes, as well as barriers and facilitators to implementing hypnosis and study procedures was also lacking. Clinical hypnosis has potential benefits for children's procedural pain and distress based on evidence of superiority to control conditions and nonpharmacological interventions (e.g., distraction, acupressure) with moderate to large effect sizes as reported in 76% of studies. However, heterogeneous interventions, contexts, study designs, and populations were identified, and the certainty of the evidence was not evaluated.

CONCLUSIONS

The review suggests potential benefits of clinical hypnosis for children's procedural pain and distress and thus provides a precursor for further systematic reviews and trials investigating the effectiveness of clinical hypnosis. The review also indicates the need to further explore the feasibility, acceptability, implementation, and safety of clinical hypnosis in children undergoing painful procedures. Based on the review, researchers implementing clinical hypnosis should adequately report interventions or use treatment manuals, follow recommended research guidelines, and assess the fidelity of intervention delivery to promote replicating and comparing interventions. The review also highlights common methodological shortcomings of published trials to avoid, such as the lack of implementation frameworks, small sample sizes, inadequate reporting of standard care or control conditions, and limited evidence on pain unpleasantness outcomes.

The effectiveness of massage interventions on procedural pain in neonates: A systematic review and meta-analysis

BACKGROUND

The painful procedures experienced by neonates during hospitalization have short-term or long-term effects on neonates. While the limitations of previous interventions make it imperative to explore effective interventions that are readily available. This systematic review and meta-analysis was conducted to evaluate the safety and effectiveness of massage for pain management in neonates.

METHODS

This systematic review was registered in PROSPER. PubMed, Embase, Cochrane Library, and the Clinical Trials Registry were searched to December 2021. Two reviewers independently carried out study selection, data extraction, bias risk assessment. Continuous data were analyzed by mean differences (MD). Dichotomous data were reported using relative risk. If at least two studies reported identical results by the same pain assessment tool, a meta-analysis was conducted using random effect model and inverse variance.

RESULTS

Total 11 included studies involving 755 neonates investigated the effects of massage on neonatal pain response compared to standard care. The meta-analysis showed that massage could effectively improve pain response in neonates compared to standard care no matter whether neonatal infant pain scale (NIPS) or premature infant pain profile (PIPP) was used as an assessment tool. Besides, massage was also effective for crying duration, blood oxygen saturation both during and after the procedure, but non-effective for the variation of respiratory rate after the procedure, and heart rate both during and after the procedure.

CONCLUSIONS

Massage may have a positive effect on pain relief of neonate, and rigorous trials are needed in the future to determine the most effective massage method.

Virtually Augmented Self-Hypnosis applied to endovascular interventions (VA-HYPO): Randomized Controlled Trial Protocol

Endovascular interventions (EVI) are increasingly performed as minimally-invasive alternatives to surgery and have many advantages, including a decreased need for general anesthesia. However, EVI can be stressful for patients and often lead to anxiety and pain related to the procedure. The use of local anesthetics, anxiolytics, and analgesic drugs can help avoid general anesthesia. Nevertheless, these drugs have potential side effects. Alternative nonpharmacological therapies can improve patients’ experience during conscious interventions and reduce the need for additional medications. The added value of virtually augmented self-hypnosis (VA-HYPO) and its potential to reduce pain and anxiety during peripheral and visceral arterial and venous EVI is unknown. This is a prospective two-arm trial designed to randomize 100 patients in two groups according to the use or not of VA-HYPO during peripheral EVI as a complementary nonpharmacological technique to improve patient comfort. The main objective is to compare per-procedural anxiety, and the secondary aim is to compare the rated per-procedural pain in both groups. The potential significance is that VA-HYPO may improve patients’ experience during peripheral and visceral arterial and venous EVI and other minimally invasive interventions performed under local anesthesia.

Techniques to Relieve Pain Associated With Botulinum Injections for Palmar and Plantar Hyperhidrosis

BACKGROUND

Palmar and plantar hyperhidrosis (HH) is a common condition characterized by excessive sweating of the palms and soles. Botulinum neurotoxin (BTX) is a very effective and safe treatment. However, the associated intense injection pain is a major limiting factor deterring patients from selecting this treatment.

OBJECTIVE

The aim of this study was to review the numerous techniques used to minimize pain accompanying injections for palmoplantar HH. Additionally, the advantages and limitations of each modality will be discussed.

MATERIALS AND METHODS

The authors performed a comprehensive literature search in PubMed/MEDLINE, Embase, Cochrane Central, and Google Scholar on randomized controlled trials, cohort studies, and case series on techniques to relieve pain of BTX injections for treatment of palmar and plantar HH.

RESULTS

Current available techniques in reducing botulinum injection with merits and drawbacks are nerve blocks, Bier blocks, cryoanalgesia, needle-free anesthesia, topical anesthetics, and vibration anesthesia.

CONCLUSION

Topical anesthesia, ice, and vibration are the safest and most convenient noninvasive available methods to relieve pain associated with botulinum injection. Nerve blocks, Bier block, and needle-free anesthesia provide better anesthesia but are limited by the need for training and equipment.

A Randomized Controlled Trial of Virtual Reality in Awake Minor Pediatric Plastic Surgery Procedures

BACKGROUND

Virtual reality has been used to alleviate pain and anxiety in a variety of medical procedures. The authors sought to explore the effects of virtual reality in common awake minor plastic surgery procedures where children may experience discomfort.

METHODS

A randomized controlled trial compared virtual reality to standard-of-care distraction among children aged 6 to 16 years undergoing awake minor plastic surgery procedures at a quaternary children's hospital. Primary outcome was change in Faces Pain Scale-Revised pain score, and secondary outcomes included change in Venham Situational Anxiety Scale score, procedure duration, administration of local anesthetic, and pain/anxiety management satisfaction.

RESULTS

Mean pain and anxiety scores were similar in both groups (p = 0.60 and p = 0.18, respectively), and procedure duration was shorter with virtual reality (22 minutes versus 29 minutes; p = 0.002). Duration remained shorter in a linear regression model accounting for procedure type (p = 0.01). Similar proportions of children received additional local anesthetic after the initial dose (virtual reality, n = 6; standard of care, n = 9; p = 0.19) and median pain management satisfaction was similar (virtual reality, 9 of 10; standard of care, 9 of 10; p = 0.41). Median anxiety management satisfaction was similar (virtual reality, 9 of 10; standard of care, 9 of 10; p = 0.05). Younger children reported more "fun" than older children with virtual reality (p = 0.02). Surgeons reported interest "using virtual reality again" in 83 percent of cases.

CONCLUSIONS

The use of virtual reality for awake pediatric plastic surgery reduced procedure time but not pain or anxiety compared to standard of care in children aged 6 to 16 years. Virtual reality was safe and well-liked and should be considered as an additional tool. Increased efficiency may allow more cases to be performed.

Effect of acupressure on procedural pain before heel lancing in neonates

OBJECTIVE

To investigate the effect of acupressure applied to UB60 and K3 acupuncture points in order to relieve the procedural pain caused by heel lancing blood sampling process in the term newborns.

METHODS

The data were collected by using the Information Form and the Neonatal Infant Pain Scale. Acupressure applied for 3 min before heel lancing blood sampling in the newborns in the experimental group (n = 31). No intervention was applied to newborns in the control group (n = 32).

RESULTS

A significant difference was found between mean scores of the newborns in the control and acupressure group in favor of the acupressure group in terms of heart rate during and after the procedure, oxygen saturation before, during and after the procedure, duration of crying during and after the procedure (P < 0.05). It was found that there was a significant difference between groups in terms of Neonatal Infant Pain Scale mean scores during (P = 0.001) and after the procedure (P < 0.05), and the difference was found to be in favor of the acupressure group.

CONCLUSION

As a result, acupressure was found to be an effective method in relieving pain caused by heel lancing blood sampling in newborns.

Improving the discomfort and satisfaction of colonoscopy by distraction with smartphones: A prospective randomized controlled study

BACKGROUND

Colonoscopy is an uncomfortable procedure. Distraction is thought to reduce pain by decreasing the amount of attention a person spends on a painful stimulus. We aimed to assess the usefulness of smartphones on discomfort associated with the colonoscopy.

METHODS

We designated 360 enrolled patients according to prospective randomized controlled study into two groups, including smartphone (SP) group (Relaxation by smartphones) and Control group (No relaxation). Measured outcomes included the discomfort, satisfaction, polyp detection rate and the willingness to repeat colonoscopy were analyzed between groups.

RESULTS

The pain and distension scores of SP group patients were significantly lower than those of the Control group (2.18 ± 2.80 vs 3.55 ± 3.07, P < .001; 4.15 ± 2.35 vs 4.79 ± 2.36, P = .011, respectively). Importantly, patient-reported satisfaction scores of the SP group were significantly higher than those of the Control group (96.45 ± 7.17 vs 91.12 ± 10.49, respectively; P < .001). Moreover, although there were no statistical differences, patients using smartphones were more likely to have shorter reach cecum times (09m:11 s vs 07m:37 s, P = .116) and more polyp detection rate (13.3% vs 9.4%, P = .246). In addition, more patients using smartphones were willing to repeat colonoscopy but no statistical difference (85.0% vs 81.7%, P = .396).

CONCLUSION

Patient using smartphone is a special manner to increase satisfaction during colonoscopy with a less discomfort and is more likely to be polyp detection rate.

Impact of music on anxiety and pain control during extracorporeal shockwave lithotripsy: A protocol for systematic review and meta-analysis

BACKGROUND

The present evidence is insufficient for evaluating the impact of exclusive music therapy on anxiety and pain control in extracorporeal shock wave lithotripsy (ESWL).

METHODS

A systematic review and meta-analysis was conducted to explore the efficacy of music therapy in reducing pain and anxiety in patients undergoing ESWL. PubMed, Web of Science, Embase, EBSCO, and Cochrane library databases (updated March 2020) were searched for randomized controlled trials assessing music therapy in reducing pain and anxiety in patients undergoing ESWL. The search strategy and study selection process were managed according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis statement.

RESULTS

Five randomized controlled trials were included in the meta-analysis. Overall, music intervention groups experienced significant reductions in pain (risk ratios = -1.20, 95% confidence intervals = -1.95 to -0.45, P = .002) and anxiety (risk ratios = -3.31, 95% confidence intervals = -4.97 to -1.84, P < .0001) compared with control groups during ESWL. Music therapy gave patient more satisfaction with the treatment and a willingness to repeat the therapy was reported. However, there was no significant difference in the stone clearance rate.

CONCLUSIONS

Listening to music can reduce patient's pain and anxiety significantly with increased therapy satisfaction and willingness to repeat.

Stress and Perception of Procedural Pain Management in Chinese Parents of Children With Cancer

OBJECTIVES

Children with cancer are exposed to repeated painful and invasive procedures. This study examines Chinese parents' stress and perception toward their children's procedural pain control.

METHODS

We recruited 265 parents of children (aged <18 years) diagnosed with hematological cancer (74.7%) and solid tumors (25.3%) from two major public hospitals. Parents used a scale (0-10) to rate perceived pain experienced by their child when undergoing lumbar puncture (LP), bone marrow aspirate, or/and biopsy. They reported their stress level and attitudes toward analgesics using the adapted Pain Flexibility Scale for Parents and Parental Medication Attitude Questionnaire. General linear modeling was used to identify factors associated with perception outcomes.

RESULTS

Parents (72.8% mothers, age 36.5 [6.8] years) expressed that they were worried (31.7%) and had difficulty with concentration (57.7%) when the child was in pain. Among parents whose children had undergone LP (n = 207), 39.1% perceived that their child still experienced severe pain (pain score >7) even with existing pain control measures. Parents reported concerns over side effects of analgesics (69.4%) and addiction (35.1%). Half of the parents (47.2%) perceived that analgesics should only be reserved for severe pain. Parents who were older (estimate = 2.07, SE = 0.87; P = 0.0054) and had lower education attainment (estimate = -3.38, SE = 1.09; P = 0.0021) had a more negative attitude toward analgesics use. Higher parental distress was associated with avoidance of analgesics use (r_s = 0.17, P = 0.0052).

CONCLUSION

Our findings suggested that subgroups of Chinese parents demonstrated distress with their child's pain and harbored misconceptions over analgesics use. Future work includes devising targeted psychoeducation interventions for these parents.

Parental presence during painful or invasive procedures in neonatology: A survey of healthcare professionals

BACKGROUND

Newborns in neonatology are exposed to invasive and painful procedures. The absence of parents during procedures revealed significantly high pain scores.

OBJECTIVE

The aim of this study was to assess practices regarding the role of parents during painful and invasive procedures.

METHODS

This was a prospective, observational, multicenter study in France in which 471 caregivers participated. Professional practices regarding the role of parents during painful procedures on their child were assessed. Univariate and multivariate analyses were performed to identify factors associated with parental presence during painful procedures.

RESULTS

Parental presence was most often allowed during capillary blood sampling, nasogastric tube insertions, and vein punctures, whereas it was mostly restricted during central line insertions, extubations, lumbar punctures, and intubations. However, we found discrepancies depending on the type of facility and caregiver seniority.

CONCLUSION

An important variability in practices concerning the role of parents during painful and invasive procedures on their child was reported.

Immersive virtual reality as analgesia for women during hysterosalpingography: study protocol for a randomized controlled trial

BACKGROUND

Hysterosalpingography (HSG) is an accepted radiologic diagnostic modality for initial infertility workup, and is generally considered uncomfortable and painful. However, the management of pain related to HSG remains inefficient. As an emerging nonpharmacologic and noninvasive pain control strategy, virtual reality (VR) distraction has been successfully used in areas such as burns, blunt force trauma, hospital-based needle procedures, dental/periodontal procedures, and urological endoscopy patients. This study aims to evaluate the analgesic effect of VR during HSG.

METHODS/DESIGN

A single-center, parallel-group, randomized controlled trial will be carried out in the Radiology Department of Yinchuan Women and Children Healthcare Hospital, Yinchuan. A total of 200 participants who are scheduled for HSG will be enrolled in this study. The participants will be randomized (1:1) into two groups: a VR group and a blank control group. The VR group will receive routine care plus immersive VR intervention and the blank control group will receive routine care. Outcomes will be monitored at baseline, immediately after HSG and 15 min after HSG for each group. The primary outcome is the worst pain score during HSG by a visual analog scale (VAS). The secondary outcomes include: affective pain, cognitive pain, and anxiety during the HSG procedure; worst pain within 15 min after HSG; patient satisfaction and acceptance with pain management; physiological parameters; adverse effects; HSG results; and immersion perception score of the VR system (for the VR condition only).

DISCUSSION

This study will focus on exploring a simply operated, noninvasive and low-cost analgesia during the HSG procedure. The results of this trial will provide data on the feasibility and safety of VR distraction therapy during HSG.

Evaluation of the use of photobiomodulation following the placement of elastomeric separators: Protocol for a randomized controlled clinical trial

BACKGROUND

Pain stemming from the placement of elastomeric separators and the exchanging of wires and accessories is the greatest reason for abandoning orthodontic treatment. Indeed, discomfort related to treatment exerts a negative impact on quality of life due to the difficulty chewing and biting. This paper proposes a study to evaluate the analgesic effects of photomiobodulation (PBM) on individuals undergoing orthodontic treatment.

METHODS

The sample will be composed of 72 individuals who receiving elastomeric separators on the mesial and distal faces of the maxillary first molars. The patients will be randomly allocated to 2 groups: an experimental group irradiated with low-level laser and a sham group submitted to simulated laser irradiation. Upon the placement of the separators, the experimental group will receive a single application of PBM on the mesial and distal cervical portion and apical third of the molars. Perceived pain will be analyzed after one hour using the visual analog scale in both groups. Samples will be taken of the gingival crevice with absorbent paper for 30 seconds for the analysis of cytokines using ELISA and the results of the 2 groups will be compared. The patients will sign a statement of informed consent. Statistical analysis will be performed with the Student's t test and analysis of variance (ANOVA).

DISCUSSION

The expectation is that the patients in the irradiated group will have a lower perception of pain and lower quantity of cytokines compared to those in the sham group. The purpose of the study is to establish an effective method for PBM with the use of low-level infrared laser (Ga-Al-As with a wavelength of 808 nm and output power of 100 mW) for reductions in pain and inflammatory cytokines related to orthodontic treatment.

This protocol was registered in ClinicalTrial.gov, under number NCT03939988. It was first posted and last updated in May 6, 2019.

Efficacy and Safety of Deep Sedation in Percutaneous Radiofrequency Ablation for Hepatocellular Carcinoma

INTRODUCTION

Radiofrequency ablation (RFA) has been accepted as safe and effective for treating early-stage hepatocellular carcinoma (HCC). However, it often causes severe pain. Therefore, in this study, we performed RFA under deep sedation and investigated its efficacy and safety.

METHODS

We conducted a retrospective study including 511 HCC patients who received approximately 886 RFA treatments between December 2014 and November 2016 at our institution. Respiratory depression was defined as oxygen saturation of below 90%; and severe body movement was defined as movement caused by pain, which was managed by lowering the power of the generator. Factors associated with respiratory depression and severe body movement were examined via univariate and multivariate regression analyses.

RESULTS

Respiratory depression occurred in 15.3% of the patients and severe body movement in 26.5% of the patients. In the multivariate analysis, BMI (≥ 25 kg/m², odds ratio [OR] = 1.75, P = 0.035) and longer ablation (≥ 10 min, OR = 2.59, P = 0.002) were significant respiratory depression-related factors. Male sex (OR = 2.02, P = 0.005), Child-Pugh class A (odds ratio = 1.96, P = 0.018), and longer ablation (≥ 10 min, OR = 3.03, P < 0.001) were significant factors related to severe body movement.

CONCLUSION

Deep sedation for RFA can be performed safely and effectively. Higher BMI and longer ablation were risk factors for respiratory depression and male sex, Child-Pugh class A, and longer ablation were independent predictors of severe body movement during RFA under deep sedation.

Interventions for intra-operative pain relief during postpartum mini-laparotomy tubal ligation

BACKGROUND

Postpartum mini-laparotomy tubal ligation (PPTL) is a contraceptive method that works by interrupting the patency of the fallopian tubes. Several methods are used for intraoperative pain relief, such as systemic administration of opioids or intraperitoneal instillation of lidocaine.

OBJECTIVES

To evaluate the effectiveness of and adverse effects associated with interventions for pain relief in women undergoing PPTL.

SEARCH METHODS

We searched for eligible studies published on or before 31 July 2017 in the CENTRAL Register of Studies Online, MEDLINE, Embase, PsycINFO, and CINAHL. We examined review articles and searched registers of ongoing clinical trials, citation lists of included studies, key textbooks, grey literature, and previous systematic reviews for potentially relevant studies.

SELECTION CRITERIA

We included randomised controlled trials (RCT) that compared perioperative pain relief measures during PPTL.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed the titles, abstracts, and full-text articles of potentially relevant studies for inclusion. We extracted the data from the included studies, assessed risk of bias, and calculated and compared results. Discrepancies were resolved by discussion, or by consulting a third review author. We computed the inverse variance risk ratio (RR) with 95% confidence interval (CI) for binary outcomes, and the mean difference (MD) with 95% CI for continuous variables.

MAIN RESULTS

We found only three RCTs, in which a total of 230 postpartum women participated. Most of our analyses were based on relatively small numbers of patients and studies. Overall, the certainty of evidence regarding the effectiveness of interventions was low, due to risk of bias and imprecision. We found very low-certainty evidence regarding the safety of interventions because of risk of bias and imprecision. Two studies had unclear risk of selection bias. One study had unclear risk of reporting bias and a high risk of other bias associated with the study protocol.Women who received an intraperitoneal instillation of lidocaine experienced lower intensity intraperitoneal pain than those given a placebo (pooled MD -3.34, 95% CI -4.19 to -2.49, three studies, 190 participants, low-certainty evidence), or an intramuscular injection of morphine (MD -4.8, 95% CI -6.43 to -3.17, one study, 40 participants, low-certainty evidence). We found no clear difference in intraperitoneal pain between women who had an intramuscular injection of morphine added to an intraperitoneal instillation of lidocaine and those who had an intraperitoneal instillation of lidocaine alone (MD -0.40, 95% CI -1.52 to 0.72, one study, 40 participants, low-certainty evidence). An intramuscular injection of morphine alone was not effective for intraperitoneal pain relief compared to placebo (MD 0.50, 95% CI -1.33 to 2.33, one study, 40 women, low-certainty evidence). None of the studies reported any serious adverse events but the evidence was very low-certainty. Intraperitoneal instillation of lidocaine may reduce the number of women requiring additional pain control when compared to placebo (RR 0.27, 95% CI 0.17 to 0.44, three studies, 190 women, low-certainty evidence).

AUTHORS' CONCLUSIONS

An intraperitoneal instillation of lidocaine during postpartum mini-laparotomy tubal ligation before fallopian tubes were tied may offer better intraperitoneal pain control, although the evidence regarding adverse effects is uncertain. We found no clear difference in intraperitoneal pain between women who received a combination of an injection of morphine, and intraperitoneal instillation of lidocaine and those who received an intraperitoneal instillation of lidocaine alone. These results must be interpreted with caution, since the evidence overall was low to very low-certainty.

Effectiveness of non-pharmacological measures for reducing pain and fear in children during venipuncture in the emergency department: a vibrating cold devices versus distraction

OBJECTIVES

To assess the effectiveness of a physical method of managing pain and fear in children and anxiety in the accompanying adult during venous puncture in the emergency department.

MATERIAL AND METHODS

Quasi-experimental study of 3 groups: one group used a combination of directed distraction by means of a vibration device with ice pack, a second group received only distraction, and no strategy was used in the third.

RESULTS

Pain and adult anxiety were similar in the 2 groups in which a pain management strategy was applied. Pain and adult anxiety were greater when no strategy was adopted. We detected no differences in the level of the children's fear.

CONCLUSION

Directed distraction can be useful for managing pain in children and it reduces the anxiety experienced by accompanying adults. The use of a vibration device with ice does not add benefits. Fear is not reduced by any of these measures.

Efficacy of the Buzzy® device for pain management of children during needle-related procedures: a systematic review protocol

BACKGROUND

Needle-related procedures are the most important source of pain in children in hospital setting. Unmanaged pain could result in short- and long-term physiological, psychological, and emotional consequences. Although the efficacy of numerous interventions has been evaluated, procedural pain management is often suboptimal in children undergoing needle-related procedures. The main objective of this systematic review is to examine the evidence for the efficacy of the Buzzy® device for needle-related procedural pain in children.

METHODS

An electronic search will be conducted in the following databases: CENTRAL, PubMed, MEDLINE, EMBASE, PsycInfo, and CINAHL. There will be no restriction regarding the language, date of publication, and publication status. Eligible studies will be randomized controlled trials using the Buzzy® device for pain management in children undergoing needle-related procedures. Selection of studies, data extraction and management, assessment of risk of bias and quality of evidence will be performed by two independent reviewers. A third researcher will be consulted in case of discrepancies. Depending on the availability and quality of the data as well as clinical and statistical heterogeneity, a meta-analysis will be performed. Otherwise, findings will be qualitatively reported.

DISCUSSION

This will be the first systematic review to examine the efficacy of the Buzzy® device on pain management of children during needle-related procedures. Results of this review will guide clinical practice and recommendations for further research to improve procedural pediatric pain management.

Pain relief for women undergoing oocyte retrieval for assisted reproduction

BACKGROUND

Various methods of conscious sedation and analgesia (CSA) have been used during oocyte retrieval for assisted reproduction. The choice of agent has been influenced by the quality of sedation and analgesia and by concerns about possible detrimental effects on reproductive outcomes.

OBJECTIVES

To assess the effectiveness and safety of different methods of conscious sedation and analgesia for pain relief and pregnancy outcomes in women undergoing transvaginal oocyte retrieval.

SEARCH METHODS

We searched; the Cochrane Gynaecology and Fertility specialised register, CENTRAL, MEDLINE, Embase, PsycINFO and CINAHL, and trials registers in November 2017. We also checked references, and contacted study authors for additional studies.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) comparing different methods and administrative protocols for conscious sedation and analgesia during oocyte retrieval.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane. Our primary outcomes were intraoperative and postoperative pain. Secondary outcomes included clinical pregnancy, patient satisfaction, analgesic side effects, and postoperative complications.

MAIN RESULTS

We included 24 RCTs (3160 women) in five comparisons. We report the main comparisons below. Evidence quality was generally low or very low, mainly owing to poor reporting and imprecision.1. CSA versus other active interventions.All evidence for this comparison was of very low quality.CSA versus CSA plus acupuncture or electroacupunctureData show more effective intraoperative pain relief on a 0 to 10 visual analogue scale (VAS) with CSA plus acupuncture (mean difference (MD) 1.00, 95% confidence interval (CI) 0.18 to 1.82, 62 women) or electroacupuncture (MD 3.00, 95% CI 2.23 to 3.77, 62 women).Data also show more effective postoperative pain relief (0 to 10 VAS) with CSA plus acupuncture (MD 0.60, 95% CI -0.10 to 1.30, 61 women) or electroacupuncture (MD 2.10, 95% CI 1.40 to 2.80, 61 women).Evidence was insufficient to show whether clinical pregnancy rates were different between CSA and CSA plus acupuncture (odds ratio (OR) 0.61, 95% CI 0.20 to 1.86, 61 women). CSA alone may be associated with fewer pregnancies than CSA plus electroacupuncture (OR 0.22, 95% CI 0.07 to 0.66, 61 women).Evidence was insufficient to show whether rates of vomiting were different between CSA and CSA plus acupuncture (OR 1.64, 95% CI 0.46 to 5.88, 62 women) or electroacupuncture (OR 1.09, 95% CI 0.33 to 3.58, 62 women).Trialists provided no usable data for other outcomes of interest.CSA versus general anaesthesia Postoperative pain relief was greater in the CSA group (0 to 3 Likert: mean difference (MD) 1.9, 95% CI 2.24 to 1.56, one RCT, 50 women).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 1.00, 95% CI 0.43 to 2.35, two RCTs, 108 women, I² = 0%).Evidence was insufficient to show whether groups differed in rates of vomiting (OR 0.46, 95% CI 0.08 to 2.75, one RCT, 50 women) or airway obstruction (OR 0.14, 95% CI 0.02 to 1.22, one RCT, 58 women). Fewer women needed mask ventilation in the CSA group (OR 0.05, 95% CI 0.01 to 0.20, one RCT, 58 women).Evidence was also insufficient to show whether groups differed in satisfaction rates (OR 0.66, 95% CI 0.11 to 4.04, two RCTs, 108 women, I² = 34%; very low-quality evidence).Trialists provided no usable data for outcomes of interest.2. CSA + paracervical block (PCB) versus other interventions.CSA + PCB versus electroacupuncture + PCB Intraoperative pain scores were lower in the CSA + PCB group (0 to 10 VAS: MD -0.66, 95% CI -0.93 to -0.39, 781 women, I² = 76%; low-quality evidence).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.96, 95% CI 0.72 to 1.29, 783 women, I² = 9%; low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus general anaesthesiaEvidence was insufficient to show whether groups differed in postoperative pain scores (0 to 10 VAS: MD 0.49, 95% CI -0.13 to 1.11, 50 women; very low-quality evidence).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.70, 95% CI 0.22 to 2.26, 51 women; very low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus spinal anaesthesiaPostoperative pain scores were higher in the CSA + PCB group (0 to 10 VAS: MD 1.02, 95% CI 0.48 to 1.56, 36 women; very low-quality evidence).Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.93, 95% CI 0.24 to 3.65, 38 women; very low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus PCBEvidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.93, 95% CI 0.44 to 1.96, 150 women; low-quality evidence) or satisfaction (OR 1.63, 95% CI 0.68 to 3.89, 150 women, low-quality evidence).Trialists provided no usable data for other outcomes of interest.CSA + PCB versus CSA only Evidence was insufficient to show whether groups differed in clinical pregnancy rates (OR 0.62, 95% CI 0.28 to 1.36, one RCT, 100 women; very low-quality evidence). Rates of postoperative nausea and vomiting were lower in the CS + PCB group (OR 0.42, 95% CI 0.18 to 0.97, two RCTs, 140 women, I² = 40%; very low-quality evidence).Trialists provided no usable data for other outcomes of interest.

AUTHORS' CONCLUSIONS

The evidence does not support one particular method or technique over another in providing effective conscious sedation and analgesia for pain relief during and after oocyte retrieval. Simultaneous use of sedation combined with analgesia such as the opiates, further enhanced by paracervical block or acupuncture techniques, resulted in better pain relief than occurred with one modality alone. Evidence was insufficient to show conclusively whether any of the interventions influenced pregnancy rates. All techniques reviewed were associated with a high degree of patient satisfaction. Women's preferences and resource availability for choice of pain relief merit consideration in practice.

[Painful procedures in small ruminants - castration of rams and bucks. - An overview]

The castration of farm animals is practiced routinely throughout the world and the procedure is subject to different levels of regulation in different countries. In Germany, painful procedures in animals are regulated by the animal welfare act. However, the indications for acceptable methods of lamb and kid castration are still under discussion. There are distinct differences between the theoretical requirements of this legislation and experiences in practice. When male lambs are kept for many months with their dams, or with ewe lambs, castration is essential to avoid unwanted pregnancies and the slaughter of pregnant females. In the opinion of the authors, it is essential that castration of small ruminants must remain possible. However, the methods used for these painful procedures need to be reassessed and if necessary new regulations established. When castration is necessary, sufficient anaesthesia and analgesia must be used irrespective of species, age and method. To make this possible potent anaesthetics and analgesics urgently need to be licensed for use in these species. This would provide an evidence base for their use and extricate veterinary practitioners from the need to use the cascade system with its associated liabilities. Current literature has been reviewed here and possible new approaches discussed in order to establish solutions that are suitable for the animals, their keepers and veterinarians.

The Effectiveness of Distraction as Procedural Pain Management Technique in Pediatric Oncology Patients: A Meta-analysis and Systematic Review

CONTEXT

Diagnostic tests and treatment regimens for pediatric cancers involve invasive and painful procedures. Effective management of such pain has been shown to be suboptimal in many parts of the world, often because of the cost and limited availability of appropriate medications. Current evidence suggests that distraction (a relatively low-cost technique) is a promising intervention for procedural pain management. There is, however, limited evidence demonstrating its effectiveness in pediatric oncology patients.

OBJECTIVES

A systematic review was conducted to ascertain the effectiveness of distraction as a procedural pain management technique in pediatric oncology patients.

METHODS

Using a comprehensive search strategy, MEDLINE, PsycINFO, Cochrane Library, AMED, CINAHL, Web of Science, and EMBASE electronic databases were searched for studies comparing distraction techniques to standard care/any intervention. Using the selected studies, a systematic review and meta-analysis of randomized controlled trials was conducted.

RESULTS

Two hundred ninety-nine studies were identified, with seven randomized control trials identified as eligible for inclusion. Pain was assessed using self-report, observer-report, and physiological measures. A meta-analysis of four studies showed distraction as effective in reducing procedural pain, based on self-reported pain. A meta-analysis of three studies, based on pulse rates, demonstrated similar results. For observer-reported pain, limited evidence supported the effectiveness of distraction.

CONCLUSION

This systematic review demonstrates that distraction is a promising intervention for procedural pain. Future research should assess effectiveness of distraction in varied populations, to explore evidence of cultural influences on pain expression, measurement, and management approaches.
