A Meta-analysis to Assess the Effectiveness of a Procedural Scale to Measure Pain in a Child Aged 0-1 Year

Background: Infant pain liability has been assessed in several studies; nonetheless, diminutive is recognized about the relevance and effectiveness of using one type of pain scale affording to the type of painful stimulus and the infant’s age. Purpose: Our purpose was to conduct a metaanalysis to assess and report on the efficiency of using the procedural pain scale to measure pain in a child aged 0-1 year using non-pharmacological interventions. Methods: A systematic search was performed up to October 2021 in PubMed and Cochrane Library. The current review enrolled randomized clinical trials (RCTs) according to PRISMA guidelines. Cochrane's risk of bias assessment was performed to assess the studies' quality and risk of bias. Meta-analyses were completed by calculating the standardized mean difference (SMD) at a 95% confidence interval (CI) using Review Manager Software. The review variables are: neonatal, pain, RCT and assessment. Results: The literature search returned 50 trials, but only 8 were involved in this meta-analysis. In most studies related to procedural pain (heel lance and vaccination), three commonly validated pain scales were used in all trials (neonatal infant pain scale NIPS, premature infant pain profile PIPP and neonatal pain, agitation and sedation scale NPASS. The 8 studies with 918 infant participants entered into analysis using effective pain scales (NIPS, PIPP and NPASS) to measure procedural pain effectively. Most studies used effective pain scales to measure procedural pain (NIPS, PIPP and NPASS). The meta-analysis showed a significant reduction in pain using NIPS, PIPP and NPASS tools. The most used was NIPS at 62.5%, followed by PIPP (25%) and NPASS (12.5%). The various interventions in studies reflected the strength of the used pain scale when assessing pain severity and supported the effect of non-pharmacological interventions (swaddling, mother holding and sucrose) in pain reduction compared with the control group (SMD 1.2, 95% CI -1.88 to -0.52, P =0.0005), I` = 95%, P>0.00001. Conclusion: In this meta-analysis, it has been reported that the pain scales used were an appropriate measure of the outcome of pain reduction. The type and accuracy of the validation of pain scales are also essential when selecting tools for a clinical trial. Implications for Nursing: The pain scales used in studies are appropriate to assess pain when measuring procedural pain (heel lance and needle-related procedures such as vaccination). Pediatric nurses should take care of selecting appropriate tools to assess pain in children before managing the pain. Further, pediatric nurses should be aware of that the inconsistency about the best tool for children is related to several factors. One is related to matching the pain tool to the age group and type of pain

Feasibility and Acceptability of the Pain Profile, a Clinical Questionnaire Aimed at Improving Pain Care.

Despite being one of the most common medical complaints, chronic pain is difficult to manage due to ineffective communication between providers and patients and time restraints during appointments. Patient-centered questionnaires have the potential to optimize communication by assessing a patient's pain history, prior treatments, and associated comorbidities to develop an effective treatment plan. This study aimed to analyze the feasibility and acceptability of a pre-visit clinical questionnaire aimed at improving communication and pain care. The "Pain Profile" questionnaire was piloted across two specialty pain clinics in a large academic medical center. Patient and provider surveys were conducted with patients who completed the Pain Profile questionnaire and providers who use it in practice. Surveys consisted of multiple-choice and open-ended questions regarding the helpfulness, usability, and implementation of the questionnaire. Descriptive analyses of patient and provider surveys were conducted. Qualitative data were analyzed using matrix framework-based coding. A total of 171 patients and 32 clinical providers completed the feasibility and acceptability surveys. 77% of patients (N= 131) found the Pain Profile helpful in communicating their pain experiences and 69% of providers (N= 22) found it helpful in guiding clinical decisions. The section that assessed the impact of pain was rated most helpful by patients (4/5) while the open-ended section asking patients to describe their pain history was rated least helpful by patients and providers (3.7/5 and 4.1/5, respectively). Both patients and providers provided suggestions to future iterations of the Pain Profile, including the addition of opioid risk and mental health screening tools. The Pain Profile questionnaire was feasible and acceptable in a pilot study at a large academic site. Future testing in a large-scale, fully powered trial is needed to assess the effectiveness of the Pain Profile in optimizing communication and pain management.

Effects of fentanyl and sucrose on pain in retinopathy examinations with pain scale, near-infrared spectroscopy, and ultrasonography: a randomized trial.

This study aimedto compare the efficacy of intravenous, intranasal fentanyl and oral sucrose inreducing the pain response during retinopathy of prematurity examinations using premature infant pain profile (PIPP) scores. The study included 42 infants who underwent retinopathy screening examinations. The infants were divided into three groups: oral sucrose, intranasal fentanyl, and intravenous fentanyl. Vital signs (heart rate, arterial oxygen saturation, and mean arterial pressure) were recorded. The PIPP was used to determine pain severity. Cerebral oxygenation and middle cerebral artery blood flow were evaluated using near-infrared spectroscopy and Doppler ultrasonography, respectively. The data obtained were compared between groups. There was no significant difference between the three groups regarding postconceptional and postnatal ages or birth weights and weight at the time of examination. All babies had moderate pain during the examination. No correlation was observed between analgesia method and pain scores (P = 0.159). In all three groups, heart rate and mean arterial pressure increased, whereas oxygen saturation decreased during the exam compared with pre-examination values. However, heart rate (HR), mean arterial pressure (MAP) and arterial oxygen saturation (sPO2) values did not differ between groups (HR, P = 0.150; MAP, P = 0.245; sPO2, P = 0.140). The cerebral oxygenation (rSO2) values between the three groups were found to be similar [rSO2: P = 0.545, P = 0.247, P = 0.803; fractional tissue oxygen extraction (FTOE): P = 0.553, P = 0.278]. Regarding cerebral blood flow values, we also did not find any difference between the three groups [mean blood flow velocity (Vmean): P = 0.569, P = 0.975; maximum flow velocity (Vmax): P = 0.820, P = 0.997]. Intravenous and intranasal fentanyl and oral sucrose were not superior to each other in preventing pain during the examination for retinopathy of prematurity (ROP). Sucrose may be a good alternative for pain control during ROP examination. Our findings suggest that ROP exam may not affect cerebral oxygenation or cerebral blood flow. Larger scale studies are needed to determine the best pharmacological option to reduce pain during ROP exams and evaluate the effects of this procedure on cerebral oxygenation and blood flow.

Comparison between combined regional nasal block and general anesthesia versus general anesthesia with dexmedetomidine during endoscopic sinus surgery

ABSTRACT Background Research findings are inconsistent regarding the efficiency of regional nasal blocks over hypotensive techniques. The current study aimed to compare regional nasal block to dexmedetomidine (DEX) for surgical field optimization. Methods A total of 70 patients (ASA I or II) aged 18 to 65 years were divided into two groups (35 patients each). The DEX group received 1 µg/kg of DEX in 10 minutes after induction of anesthesia, followed by 0.7 µg/kg/hour during maintenance of anesthesia. The other group [Sphenopalatine ganglion block (SPGB) group] was subjected to regional nasal block by SPGB immediately after induction of general anesthesia. This was done via a transoral approach using 2 ml of a mixture of lidocaine (2%) and bupivacaine (0.5%) for each side. Results Surgical conditions were satisfactory in all patients of both groups, but significantly better with bilateral SPGB. In addition, the block group had also improved extubation characteristics and postoperative analgesia. Patients who received bilateral SPGB complained significantly of dental numbness. Conclusions Both DEX and regional nasal block provided excellent functional endoscopic sinus surgery (FESS) with a high score of surgeons’ satisfaction. The SPGB can provide better surgical field optimization with less blood loss, less intraoperative analgesic consumption, and early extubation with minor complications, and better immediate postoperative pain profile. So, SPGB can be used efficiently and safely in combination with general anesthesia in patients undergoing FESS.

Stress and pain regulation: Parallel processes among traumatized individuals

IntroductionThe human reaction to traumatic events is often marked by a dialectic alteration of two emotional states –a state characterized by intrusion, anxiety and hyperarousal, and a state of denial marked by dissociation and numbing. These two seemingly opposite states represent attempts to modulate stress, as gradual reduction of their intensity represents an adaptation to stress. Maladaptive reactions to trauma, however, reflect disrupted regulation capacities, manifested as persistent over-modulation or under-modulation of stress.ObjectivesTo demonstrate that these manifestations of disrupted regulation, as observed among individuals with posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD) are also reflected in patterns of pain modulation.MethodsThree studies using self-report questionnaires and psychophysical tests, assessing sensitivity to pain, as reflected by pain thresholds, and reactivity to suprathreshold noxious stimuli, as implicated in their ratingResultsStudy 1 Included 32 PTSD outpatients, 29 anxiety disorder outpatients, and 20 healthy controls. PTSD patients reported higher rates of chronic pain (83.3%) than anxiety patients (42.0%) and controls (5.0%). PTSD severity correlated with chronic pain severity (r = 0.61, p < 0.01). PTSD patients displayed a unique paradoxical pain profile, according to which their pain thresholds were significantly higher than those of the anxiety patients and controls (p < 0.01), but they perceived suprathreshold stimuli as being much more intense (p < 0.01).Study 2 included 32 PTSD outpatients and 43 healthy controls. Findings replicated the paradoxical pain profile among PTSD patients. Pain thresholds were positively associated with dissociation level (b = 0.49; p < 0.05) and negatively associated with anxiety level (b = -0.63, p < 0.01). Pain ratings were positively associated with anxiety (b = 0.52, p < 0.05) and negatively related to dissociation levels (b = -.51, p < 0.05).Study 3 included 46 women diagnosed with BPD and 47 healthy controls. Women with BPD reported higher levels of childhood trauma (p < 0.05) than the controls. They also demonstrated higher pain thresholds (p < 0.05). Among subjects with high levels of body dissociation, implicated by reduced body awareness, those with BPD demonstrated hyposensitivity to pain, manifested in higher pain thresholds, lower suprathreshold pain ratings, and pain evoked by higher temperature, than the controls. Among those with low levels of body dissociation, BPD subjects demonstrated increased reactivity to pain as manifested in higher pain ratings and pain evoked by lower temperature.ConclusionsThese findings demonstrate the association between over-modulation and under-modulation of stress and over-modulation and under-modulation of pain, respectively, among PTSD and BPD patients. These findings point to parallel processes of disrupted regulation among traumatized individuals.Disclosure of InterestNone Declared

The Role of Substance P, Neurokinin A, Neuropeptide Y, and Cortisol in Assessing Neonatal Pain.

Introduction: Our aim was to investigate biomarkers of neonatal pain and their association with two pain scales. Methods: This prospective study included 54 full-term neonates. Levels of substance P (SubP), neurokinin A (NKA), neuropeptide Y (NPY), and cortisol were recorded and two pain scales (Premature Infant Pain Profile [PIPP] and Neonatal Infant Pain Scale [NIPS]) were used. Results: A statistically significant decrease in the levels of NPY (p = 0.02) and NKA (p = 0.03) was detected. A significant increase in NIPS scale (p < 0.001) and PIPP scale (p < 0.001) postpainful intervention was also detected. There was a positive correlation between cortisol and SubP (p = 0.01), NKA and NPY (p < 0.001) and between NIPS and PIPP (p < 0.001). A negative correlation was found for NPY with SubP (p = 0.004), cortisol (p = 0.02), NIPS (p = 0.001) and PIPP (p = 0.002). Conclusions: Novel biomarkers and pain scales may help in designing an objective tool for the quantification of neonatal pain in the everyday practice.

Development of two outpatient interdisciplinary group modules in the treatment of patients with pain and risk of chronification

An early treatment of patients who suffer from pain and show risk factors for chronification is meaningful as these patients can benefit from an early interdisciplinary multimodal pain treatment (IMST). In view of the insufficient treatment, two outpatient treatment modules for the secondary prevention of pain chronification are developed within the framework of PAIN2020: the educative and accompanying IMST (E‑IMST and B‑IMST). The developmental process of both IMSTs is presented. In this context two target groups of patients were defined for which 1session (E‑IMST) or 10intervention appointments (B‑IMST) were planned, depending on the chronification, impairment and complexity of the disorder. The conception was carried out in five steps: development of the objectives, development of the main contents, workshop on the content and conceptional design (contents, mediation, exercises), preparation of atime schedule and processing of the results (manual, presentations, worksheets, handbook). The B‑IMST was initially developed from which the contents for the E‑IMST were subsequently extracted. Additionally, aconcept for testing the feasibility and aworking model for apilot study were developed. The objectives for both forms of IMST are improvement of the understanding of pain and contributing factors, the increase of the experience of control and self-efficacy and the increase in self-responsibility with respect to strategies to reduce pain. Differences between the two treatment modules arise from the needs and framework conditions. Medical, physiotherapeutic and psychotherapeutic contents and schedules were organized for both IMST modules. The B‑IMST consists of five modules each with two sessions as group interventions (biopsychosocial model, activation planning, regulation of needs, sleep and medication, routine transfer). The 3‑h E‑IMST group intervention mainly intends to mediate knowledge on pain and the biopsychosocial pain model. Theoretical and practical interventions, empirical knowledge and experience-oriented methods are employed. There are now two interdisciplinary structured manuals for the secondary preventive treatment of patients with recurrent pain and arisk profile for chronification. These approaches must now prove themselves with respect to feasibility and effectiveness.

The effect of swaddling method applied to preterm infants during the aspiration procedure on pain

PurposeThe study was carried out to determine the effect of the swaddling method on pain in preterm infants (between 27 and 36 weeks) hospitalized in the Neonatal Intensive Care Unit during the aspiration procedure. Preterm infants were recruited by convenience sampling from level III neonatal intensive care units in a city in Turkey. MethodThe study was conducted in a randomized controlled trial manner. The study consisted of preterm infants (n = 70) receiving care or treatment at a neonatal intensive care unit. While swaddling was applied to the infants in the experimental group before the aspiration process. The pain was assessed before, during, and after the nasal aspiration using the Premature Infant Pain Profile. ResultsNo significant difference was found in terms of pre-procedural pain scores whereas a statistically significant difference was detected in terms of pain scores during and after the procedure between the groups. ConclusionIt was determined in the study that the swaddling method reduced the pain of the preterm infants during the aspiration procedure. Implications for practiceThis study emphasized that swaddling had pain-reducing during the aspiration procedure in the neonatal intensive care unit in preterm infants. It is recommended that future studies be conducted using different invasive procedures in preterm infants born earlier.

The Relationship between Pain and Spasticity and Tell-Tale Signs of Pain in Children with Cerebral Palsy.

Pain and quality of life are closely interrelated in children with cerebral palsy (CCP). Even though 67% of CCP experience pain, it is overlooked and untreated. In this study, our purpose was two-fold: first, to examine the relationship between pain and spasticity by evaluating the effects of AbobotulinumtoxinA/Dysport (BoNT), and second, to describe the symptoms and location of pain in CCP. The subjects were 22 CCP in at least moderate pain. They were evaluated for spasticity by the modified Ashworth and Tardieu scale and for pain by the r-FLACC and the pediatric pain profile. After one injection of BoNT, the subjects were re-evaluated. We found a significant reduction in pain, but no significant relationship between the reduction of pain and spasticity. We found no association between the dose of BoNT and pain or spasticity. Pain in the lower extremity was located primarily in the hip region. The effect of ultrasound-guided intermuscular injections of BoNT suggests that pain in CCP has an extra-articular component. We found that pain in CCP manifests as specific tell-tale signs and problems in daily living. In conclusion, we found no relationship between pain and spasticity. Signs and manifestations of pain are described in detail. Lower extremity (hip) pain seems to have a soft tissue/extra-articular component.

Effect of Non-Pharmacological Methods in the Reduction of Neonatal Pain: Systematic Review and Meta-Analysis.

In neonatology, neonates have traditionally been considered incapable of feeling pain, due to the immaturity of their nervous system. Currently, there is sufficient information on the perception of pain in neonates; however, this treatment at this crucial stage for development requires a better approach. For this reason, the aim of this study was to analyse the efficacy of non-pharmacological analgesia interventions during heel prick, and to assess their effects on heart rate (HR), premature infant pain profile (PIPP) and O2 saturation. A systematic review and meta-analysis was performed following the guidelines of the preferred reporting items for systematic reviews and meta-analyses (PRISMA), and the Cochrane collaboration handbook. The databases PubMed, Cochrane Library, Web of Science, Scopus, CINAHL and Science Direct were searched until the end of January 2022. The DerSimonian and Laird methods were used to estimate the effect size with a 95% confidence interval (CI95%). Effect size estimates were 0.05 (95% CI: -0.19, 0.29) for HR, -0.02 (95% CI: -0.24, 0.21) for PIPP scale, and -0.12 (95% CI: -0.29, 0.05) for O2 saturation. The non-pharmacological interventions analysed (breastfeeding, kangaroo-mother care method, oral sucrose and non-nutritive sucking) were not statistically significant in reducing neonatal pain, but did influence the decrease in pain score and a faster stabilisation of vital signs.

The effectiveness of repeated sucrose for procedural pain in neonates in a longitudinal observational study.

To determine the analgesic effectiveness of repeated sucrose administration for skin-breaking (SB) procedures over the Neonatal Intensive Care Unit (NICU) hospitalization of preterm infants. Longitudinal observational study, conducted in four level III Canadian NICUs. Eligible infants were <32 weeks gestational age at birth, and <10 days of life at enrollment. Infants received 24% sucrose (0.12 ml) prior to all painful procedures. The Premature Infant Pain Profile - Revised (PIPP-R) was used at 30 and 60 seconds after a medically-required SB procedure as soon as possible after enrollment and weekly up to three additional times for scheduled procedures. 172 infants (57.3% male, gestational age 28.35 (±2.31) weeks) were included. The mean 30 s PIPP-R scores were 6.11 (±3.68), 5.76 (±3.41), 6.48 (±3.67), and 6.81 (±3.69) respectively; there were no statistically significant interactions of study site by time (p = 0.31) or over time (p = 0.15). At 60 s, mean PIPP-R scores were 6.05 (±4.09), 5.74 (±3.67), 6.19 (±3.7), and 5.99 (±3.76) respectively; there were no study site by time interactions (p = 0.14) or differences over time (p = 0.52). There was a statistically significant site difference in the effectiveness of sucrose at 30 and 60 seconds (p < 0.01). Consistently low PIPP-R scores following a skin-breaking procedure indicated that the analgesic effectiveness of the minimal dose of sucrose was sustained over time in the NICU. Further research is required to determine the optimal combination of sucrose and other pain management strategies to improve clinical practice and the impact of consistent use of repeated use of sucrose on neurodevelopment.

The effect of using maternal voice, white noise, and holding combination interventions on the heel stick sampling

BackgroundHeel stick sampling, a common procedure in newborns, causes acute pain. AimsThis study aims to measure the outcome of five various non-pharmacologic pain relief groups; maternal voice, white noise, holding, maternal voice+holding, and white noise+holding. MethodsThe study is an open label, randomized controlled trial. A total of 178 newborns were included in this study. Newborns were randomly allocated to each group; white noise (n = 31), maternal voice (n = 31), holding (n = 30), white noise+holding (n = 29), maternal voice+holding (n = 28), and control (n = 29) interventions. Newborns' pain responses were evaluated using the Neonatal Infant Pain Scale (NIPS), and the Premature Infant Pain Profile (PIPP). The primary measured outcomes were the newborns' pain levels, while the secondary outcomes were the heart rate and changes in oxygen saturation. The mean values of pain in neonates between groups were evaluated one minute before (Phase1), during (Phase2), and one minute after (Phase3) the procedure. ResultsThe research results are given with comparisons in three time periods (Phase1, Phase2 and Phase3). White noise and white noise+holding were found to have the lowest mean NIPS and PIPP score (p < 0.001). The mean heart rate was found to be the lowest in the white noise+holding group (p < 0.001). There was no significant difference between the groups in terms of oxygen saturation score (p = 0.453). ConclusionThe white noise+holding applied to newborns during heel stick sampling were effective in pain reduction. Nurses and midwives can use white noise+holding method. Implications to practiceThese results contribute to the pain management of newborns.

Effect of Music on Infant Stress as Measured by Cortisol Levels and Premature Infant Pain Profile: A Systematic Review with Meta-analysis

Hospitalized infants often experience pathological stress and pain with adverse short and long term effects on health outcomes. However, data regarding the benefits of music therapy for infant stress and pain are conflicting.

Preliminary outcomes of the COVID-19 pandemic: a new chronic pain profile

In summing up the preliminary results of the COVID-19 pandemic that has not yet ended, modern research pays much attention to the so-called post-COVID syndrome, which includes the long-term consequences of the disease. In English, symptoms are reported as long COVID, post-acute COVID, or chronic post-COVID syndrome and are described as symptoms of fatigue, respiratory disorders, memory, and sleep problems. Symptoms such as muscle pain and decreased endurance when performing habitual physical exertion are mentioned much less often. Meanwhile, among the complaints of those who have been ill, this symptom is present quite often, reducing the quality of life and tolerability of normal physical exertion. This review aimed to provide an in-depth study of a new type of the chronic myofascial pain syndrome after COVID-19, i.e., the frequency of occurrence, causes of the development, and pathophysiology of chronic pain syndrome associated with COVID-19 and manifested as fibromyalgia of various localizations. To answer the questions posed, the authors searched for information in four electronic databases. The key search terms used were COVID-19, long COVID, and signs and symptoms of pain syndrome. A review of current literature data has shown that close study and dynamic monitoring of patients who had COVID-19 can contribute to further deciphering the pathophysiological mechanisms of the development of its long-term consequences and provide answers to questions on the prevention and treatment of chronic pain syndrome in this patient cohort.

Efficacy of Enhanced Dose of Expressed Breast Milk in Neonatal Procedural Pain Relief: A Randomised Placebo-controlled Study

Introduction: Procedural pain remedies in neonates is an area of active research due to better understanding of short and long-term outcomes of neonatal painful exposures. Non pharmacological interventions are especially attractive as it avoids unnecessary drug exposure. While dextrose is known to be effective, results with small volumes (2 mL) of Expressed Breast Milk (EBM) are equivocal. There is recent theoretical evidence to show that larger doses of EBM may be more efficacious. Aim: To compare the efficacy of a larger volume of EBM 5 mL and 2 mL of 25% Dextrose (25D) in relief of procedural pain from venipuncture in term and preterm neonates. Materials and Methods: A single center randomised placebo- controlled study was conducted at Bokaro General Hospital, Bokaro Steel City, Jharkhand, India, between March 2014 and February 2016. Neonates ≥34 week gestation, requiring venipuncture in a neonatal care unit were randomly allocated into 3 equal groups using a random number table- Sterile Water (SW), 2mL 25D, 5 mL EBM was given two minutes prior to venipuncture. Video of facial response, cry times, Maximal Heart Rate (MHR), and minimum Oxygen Saturation (SpO2) were recorded till five minutes after venipuncture. The Premature Infant Pain Profile (PIPP) score was used to assess the effect of the interventions on procedural pain. Subgroup analysis was done in term and preterm neonates. Continuous variables were presented as mean±SD or median. Categorical variables were expressed as frequencies and percentages. The comparison of normally distributed continuous variables between the groups was performed using Analysis of Variance (ANOVA). Results: The PIPP score in the 25D group (2.94±1.41) was significantly lower than the EBM (7.42±1.69) and SW (10.56±1.69) groups (p-value&lt;0.001). MHR was significantly lower in the 25D group, but no difference was found between the EBM and SW groups (p-value=0.23). SpO2 was significantly higher in the 25D group but for the initial 2.5 minutes only. Cry times were significantly lower in the intervention groups. There was no difference in outcomes in term vs. preterm infants. Conclusion: The use of 2 mL 25D was more effective in reducing procedural pain from venipuncture compared to 5 mL EBM. The return of physiological markers (MHR and SpO2) to baseline were faster and more complete in the 25D group.

Comparison of 25% Dextrose versus Expressed Breast Milk in Reducing Pain while Heel Prick Procedure in Preterm Neonates in a Tertiary Care Hospital, Vadodara, Gujarat, India: A Randomised Clinical Trial

Introduction: Preterm infants undergo repeated painful procedures during a period of rapid brain development and programming of stress systems. Newborn babies including preterm infants do feel pain. Although different interventions, such as skin-to-skin contact, glucose solutions, breastfeeding, and local anaesthetic agents, have been evaluated to reduce infants’ pain, there is no clinical trial available to identify the best method. Aim: To compare the dectrose 25% versus Expressed Breast Milk (EBM) in reducing pain while heel prick procedure in preterm neonates in a tertiary care hospital. Materials and Methods: The present randomised clinical trial was conducted at Neonatal Intensive Care Unit (NICU) of Kashiben Gordhandas Patel Children Hospital, Vadodara, Gujarat, India, from September 2019 to May 2020. Total 125 neonates with Gestational age between 28 weeks to 36 weeks were included in the study. Babies were divided into two groups by randomisation: Group-A: EBM and Group-B: Dextrose 25%. Premature Infant Pain Profile (PIPP) score was calculated from worst state of individual recovery period (0-½ minute, 1-1½ minute, 3-3½ minute) and compared to baseline period PIPP. Results: Mean gestational age on examination in Group-A was 34.48±6.14 weeks and in Group-B were 34.51±5.89 weeks. Out of total 125 preterm babies (Group-A-62, group B-63), 71 (56.8%) were male and 54 (43.2 %) were females. Comparison of PIPP at 1-1½ min of heel prick in EBM and Dextrose 25% group was statistically significant (p-value &lt;0.003) suggestive of continued analgesic effect of dextrose 25% better than EBM and PIPP scores after 3-3½ min of heel prick having no statistically significant difference. (p&gt;0.05) Mean difference between the PIPP score in the dextrose 25% and EBM groups was -1.25 and -1.33 at 0 and 1 minute after procedure (p-value,&lt;0.001), so pain relief was better in dextrose 25% group than EBM group. Conclusion: Dextrose 25% was better effective in reducing mean crying duration than EBM. Dextrose 25% had a better analgesic effect than EBM in 28 to 36 weeks gestational age neonates.

Agreement of Revised Premature Infant Pain Profile Scoring between Healthcare Providers and Laypersons: A Cross-sectional Study

Introduction: The experience of pain during the neonatal period has short and long-term consequences. The Revised Premature Infant Pain Profile (PIPP-R) is a globally accepted and validated tool for assessing pain in neonates. Adequate pain management measures can be implemented using the PIPP-R, even in the absence of consultants. Aim: To assess the agreement among healthcare providers and laypersons in scoring the PIPP-R. Materials and Methods: A cross-sectional study was conducted at Shree Krishna Hospital, a rural Tertiary Care Teaching Hospital in central Gujarat, India. The duration of the study was one year and six months, from January 2021 to June 2022. The study included 12 volunteers from various fields, such as consultant neonatologists, first year postgraduate students in Department of Paediatrics, neonatal nurses, social workers, Bachelor of Medicine, Bachelor of Surgery (MBBS) interns, and mothers of newborns. A neonatology consultant provided training on the PIPP-R scoring system using handouts and a presentation. The volunteers then evaluated 100 prerecorded videos of newborns undergoing painful procedures. Agreement between volunteers for the total PIPP-R score and its subcomponents was assessed using Bland-Altman analysis and Cohen’s Kappa statistics. Results: A total of 100 videos of newborns (51 girls, 49 boys) undergoing painful procedures were evaluated for the PIPP-R score. The mean age, gestational age, and birth weight of the newborns were 2.21±1.55 days, 37±2.44 weeks, and 2.56±0.72 kg, respectively. The procedures included heel prick for Random Blood Sugar (RBS) (44%), intravenous sampling/insertion (34%), and intramuscular vitamin K injection (22%). The mean difference with 95% Confidence Limits (CL) of total PIPP-R scores between the two consultants (neonatologists) was -0.640 (-5.196, 3.916). The length of the CL was -9.112, which fell outside the defined CL of 4.2 (20% of the total score), indicating unacceptable agreement between the two consultants. Similarly, agreement between each consultant and any of the other participants, including residents, nurses, interns, mothers, and social workers, regarding the total PIPP-R score, as well as its subcomponents, was also deemed unacceptable. Conclusion: The present study concluded that the inter-rater reliability of the PIPP-R score and its subcomponents was unacceptable between consultants and with any of the other participants.

Pain and Inflammation Profile of a Degenerated Intervertebral Disc

Degenerative disc disease (DDD) is characterised by progressive intervertebral disc (IVD) inflammation that ultimately causes lower back pain. The available therapeutic approach for DDD is the management of pain and spinal infusion. In the present investigation, the rat needle punctured disc degeneration model was established under a fluoroscopically guided system, followed by human umbilical cord mesenchymal stem cells (hUC-MSCs) transplantation. The IVD degeneration was examined and confirmed by radiography, histology, and pain and inflammatory marker evaluation. A rat tail disc degeneration model was developed with three successive coccyx IVDs. The needle was inserted into the IVD under fluoroscopic guidance, and its tip was inserted through the lateral annulus fibrosus into the nucleus pulposus (NP) region, twisted 360o twice, and held for 30 seconds. To assess the IVD height from radiography images 2 weeks after disc puncture and MSC transplantation to evaluate the degree of IVD degeneration and regeneration, The pain and inflammatory molecular markers were quantified using qPCR. To assess the severity of IVD degeneration and regeneration, histology was performed using haematoxylin and eosin (H &amp; E) and alcian blue staining. MSCs were successfully isolated from human umbilical cord tissue and exhibited fibroblast-like morphology. Radiographic imaging and histological analyses showed significant IVD degeneration after 2 weeks of injury, and the hUC-MSC group exhibited the restored NP region and significant presence of proteoglycans in contrast to the degenerated group. When compared to healthy IVDs, the molecular expression of pain and inflammatory genes was significantly increased on days 2 and 5, resulting in an immunomodulatory response and a marked IVD degeneration. Conversely, the hUC-MSC group at 2 and 5 days showed significantly downregulated expression of C-JUN, C-FOS, AKT, OPG, RANK, TLR4, and IL-1β compared to the degenerated IVDD group. Moreover, the hUC-MSCs-treated group indicated significant NP hydration. The preclinical transplantation of hUC-MSCs can potentially reduce the pain and inflammation caused by disc degeneration. Therefore, the therapy can ideally deal with all the manifestations that occur due to such debilitating DDD.

High Degree Spondylolisthesis in Adults: Monosegmental Reduction and Fixation in Our Perspective

Objective: To evaluate a method to reduce high degree spondylolisthesis in adults with monosegmental fixing preserving the adjacent level and the improvement of sagittal balance. Methods: A prospective study, with 8 adult patients with high degree spondy\olisthesis (III and IV) in adults who underwent surgery by the same team. We included 5 women and 3 men with a mean age of 37 years that had no improvement with conservative treatment. The surgical technique used was total or partial reduction by Spondylolisthesis Reduction Instrument SRI System. Results: The L5-S1 level was involved in five patients, L4-L5 in two and VT-S1 in one patient. Isthmic type predominated in five patients, followed by dysplastic type in two and one a-spondytolisthesis. These patients were assessed by the Oswestry scale. Which showed a preoperative average of 59% and postoperative average of 12.4%. Conclusion: The method of high- grade spondylolisthesis reduction with instrumentation only at the affected level is a treatment option with good results, with control of the pain profile and functional improvement in patients.
