Ovarian Puncture Triggers an Inflammatory Response that did not Affect Late Folliculogenesis, Ovulation Rate, and Fertility.

Ovarian puncture has been widely used in assisted reproduction, but there are still gaps about its effects on ovarian morphophysiology, as well as the relationship between inflammation caused by this procedure and the follicular growth and fertility. The aim of this study was to investigate the effects of ovarian puncture on folliculogenesis and fertility. Mice (n = 24) were divided into two groups: (1) SHAM-both ovaries were exposed and repositioned and (2) Punctured-ovaries were exposed, punctured, and repositioned. After 96 h of surgery, ovaries were collected for morphofunctional analysis. New females were used for the superovulation (n = 10) and fertility assays (n = 10). Increased volumetric density of inflammatory cells-p = 0.0005, p = 0.0013; hemorrhagic foci-p < 0.0001; and inflammatory exudate-p < 0.0001 could be noticed on the punctured group, compared to SHAM. The percentage of primordial follicles was lower on the punctured ovaries (p = 0.00294). Ovarian puncture has also induced an increase in the proliferation of granulosa cells of primary (p = 0.0321) and antral follicles (p = 0.0395), and an increased apoptotic index of antral follicles (p = 0.0100). There was no influence on expression of some genes related to inflammation, collagen deposition and folliculogenesis progression. The reproductive aspects (oocyte retrieval and number of fetuses per female) were not altered (p > 0.05). Taken together, our findings strongly suggest that ovarian puncture results in a local inflammation that affects follicular growth and atresia. However, it does not affect female fertility, which strengthens the safety of this procedure.

CECAL SLURRY AS AN ALTERNATIVE MODEL TO CECAL LIGATION AND PUNCTURE FOR THE STUDY OF SEPSIS-INDUCED CARDIOVASCULAR DYSFUNCTION.

ABSTRACT: Sepsis is a life-threatening condition widely studied by animal models. Cecal ligation and puncture (CLP) is still regarded as the gold standard model for sepsis. However, CLP has limitations due to its invasiveness and variability. Cecal slurry (CS) model is a nonsurgical and thus less invasive alternative. However, the lack of standardization of the CS model in the literature limits its practical application. Additionally, it is not well studied whether CS model reproduces septic cardiovascular dysfunction in rats, which is a crucial issue in septic patients. Thus, this study aimed to standardize the CS model in Wistar rats and evaluate sepsis-induced cardiovascular dysfunction compared to CLP. Our results showed that CS model induced important features of sepsis cardiovascular dysfunction 24 h after its onset, such as hypotension, tachycardia, and decreased contractile response to vasoconstrictors both in vivo and ex vivo as well changes in renal blood flow. Increases in blood lactate, AST, ALT, creatinine, and urea indicated organ dysfunction. CS model also induced increased production of nitric oxide metabolites and bacterial spread to tissues. CS model causes less animal suffering, it is a nonsurgical model, and, more importantly, it replicates the cardiovascular dysfunction induced by sepsis with better homogeneity than CLP. Therefore, CS model serves as an alternative and possibly as a better model for sepsis research.

Effect of photobiomodulation therapy on pain perception during anesthetic puncture of dental local anesthesia: A systematic review.

BACKGROUND: Local anesthetic puncture is often related to the experience of pain. This study aimed to systematically analyze the literature on changes in pain perception during the anesthetic puncture of dental local anesthesia after Photobiomodulation Therapy (PBMT). MATERIAL AND METHODS: An electronic search was performed in eight primary databases (Embase, LILACS, BBO, LIVIVO, MedLine via PubMed, SciELO, Scopus, and Web of Science) and three additional ones (EASY, Google Scholar, and OATD) to partially capture the "gray literature". The PICO strategy was used to identify randomized clinical trials evaluating the analgesic effect of PBMT in the anesthetic puncture site of dental local anesthesia compared to placebo or control groups, without restrictions on publication language and year. Two reviewers extracted the data and assessed the individual risk of bias of the eligible studies using the Cochrane Collaboration Risk of Bias Tool version 2.0. RESULTS: The electronic search found 3,485 records, of which eight met the eligibility criteria and were included in the qualitative synthesis. The studies were published from 2011 to 2022. None of the included studies had a low risk of bias. PBMT groups showed no significant difference in pain scores compared to placebo and control groups of most studies. CONCLUSION: Based on a low to very low certainty of evidence, PBMT seems to have no effect on pain perception during anesthetic puncture in patients undergoing dental local anesthesia.

A rare vascular injury in a blood donor after whole blood donation.

BACKGROUND: Blood donation is a safe process though reactions may still occur. We describe a rare vascular complication in a frequent donor, with improvements in the collection process aimed at avoiding future events. METHODS: A 63-year-old woman presented with local pain and an apparent collection in the left arm 8 days after donation. Duplex ultrasound identified a superficial liquid collection and signs of arteriovenous fistula (AVF) between the cubital vein and an arterial branch. A computed tomography (CT)-angio performed 1 day after ultrasound did not identify signs of AVF, followed by a new duplex which confirmed CT-angio findings. It was assumed that a traumatic AVF evolved with spontaneous thrombosis. In the early follow-up (18 days), a progressive regression of hematoma was observed without any sequelae. RESULTS: Investigation showed a faster whole blood bag collection time (3 min; normal: 5-9 min), and the processed packed red blood cell had a brighter red color than usual. The donor reported local bleeding after needle withdrawal, not observed in previous donations and a bruise forming on the same day. No arterial puncture (AP) was noticed by the collection staff during the procedure. The staff was retrained and actions were taken focusing on more active surveillance of late reactions, highlighting the importance of post-donation information by the donors, regardless of any adverse reaction observed, to detect late complications. CONCLUSION: We described an uncommon AP in a donor that was not identified, leading to an AVF that spontaneously thrombosed.

The Technique for Transorbital Ventricular Puncture: An Anatomic Approach.

BACKGROUND AND OBJECTIVES: Transorbital ventricular puncture is a minimally invasive described procedure with poor landmarks and anatomic references. This approach can be easily performed to save patients with intracranial hypertension, especially when it is secondary to an acute decompensated hydrocephalus. This study aims to describe anatomic structures and landmarks to facilitate the execution of transorbital puncture in emergency cases. METHODS: We analyzed 120 head computed tomographies to show the best area to perform the procedure in the orbital roof. Two adult cadavers (4 sides) were punctured in the predetermined area. Angles, distances, landmarks, and anatomic structures were registered. This approach to the ventricular system may be performed at bedside to relieve intracranial hypertension only in specific cases. RESULTS: The perforation point is 2.5 cm (female) or 3.0 cm (male) lateral to the midline and immediately inferior to the superciliary arch. A vertical line, parallel to midline, was drawn on the outer edge of the patient's forehead, the needle was 45° inferiorly and 20° medially and then progressed 2.0 cm backwards to reach the bone perforation point. After that, it was advanced another 4.5cm approximately until it reached the anterior horn of the lateral ventricle. CONCLUSION: Based on statistical and experimental evidences, we were able to establish reliable anatomic reference points to access the anterior horn of the lateral ventricle through transorbital puncture.

Use of photobiomodulation (880 nm) for anesthesia puncture pain reduction: A split-mouth case report.

The objective of this split-mouth case report is to evaluate the effect of photobiomodulation (PBM, 880 nm) on pain control during pterygomandibular puncture. A patient received anesthesia on both sides of the mouth in a randomized manner. On the right side, an 880-nm infrared laser was applied immediately before local anesthesia. On the left side, a sham laser was applied using the same technique. There was a 50% reduction in pain levels on the PBM-treated side compared to the PBM-sham side, as measured by the visual analog scale. Sensitivity tests revealed that anesthesia was more effective on the PBM side. There was no difference in blood pressure. This case report suggests that PBM (880 nm) before anesthesia may alleviate puncture pain associated with pterygomandibular anesthesia. Although these findings are based on a single case report, they can serve as the initial stepping stone for further randomized clinical trials.

Sepsis sensitizes behavioural amphetamine responses while inducing inflammatory and neurotrophic vulnerability in the cecal ligation and puncture model.

The present study aimed to evaluate if sepsis sensitizes behavioural and biochemical responses induced by m-amphetamine. For this, Wistar rats were submitted to the cecal ligation and puncture. After 30 days of cecal ligation and puncture procedure, the animals were submitted to a single intraperitoneal injection of saline or m-amphetamine (.25, .50, or 1.0 mg/kg). Locomotor behaviour was assessed 2 h after the administration. Interleukin (IL)-1ß, IL-6, IL-10, tumour necrosis factor-α, dopamine-cAMP-regulated phosphoprotein of 32,000 kDa (DARPP-32) and neuronal calcium sensor (NCS-1) levels were evaluated in the frontal cortex, hippocampus and striatum. Also, brain-derived neurotrophic factor (BDNF), neuronal growth factor and glial-derived neurotrophic factor levels were assessed in the hippocampus. M-amphetamine alone (.25 and 1.0 mg/kg) increased rats' locomotion and exploratory behaviour compared with the Sham + Sal. Animals from the cecal ligation and puncture + m-amphetamine (.5 and/or 1.0 mg/kg) group showed an increase in locomotion, exploratory and risk-like behaviour when compared with the Sham + Saline group and with its respective Sham groups. Cecal ligation and puncture increased interleukin levels compared with the Sham + Sal. However, cecal ligation and puncture animals that received m-amphetamine (1 mg/kg) increased even more, these inflammatory parameters compared with the Sham + Sal and the cecal ligation and puncture + saline group. M-amphetamine at lower doses increased neurotrophic factors, but higher doses decreased these parameters in the brain of cecal ligation and puncture rats. M-amphetamine dose-dependently increased DARPP-32 and NCS-1 levels in cecal ligation and puncture rats in some structures. In conclusion, these results demonstrate that sepsis sensitizes behavioural amphetamine responses while inducing inflammatory and neurotrophic vulnerability in the cecal ligation and puncture model.

Pediatricians' focus of sight at pain assessment during a neonatal heel puncture.

OBJECTIVE: To evaluate the focus of pediatricians' gaze during the heel prick of neonates. METHODS: Prospective study in which pediatricians wearing eye tracker glasses evaluated neonatal pain before/after a heel prtick. Pediatricians scored the pain they perceived in the neonate in a verbal analogue numerical scale (0=no pain; 10=maximum pain). The outcomes measured were number and time of visual fixations in upper face, lower face, and hands, in two 10-second periods, before (pre) and after the puncture (post). These outcomes were compared between the periods, and according to pediatricians' pain perception: absent/mild (score: 0-5) and moderate/intense (score: 6-10). RESULTS: 24 pediatricians (31 years old, 92% female) evaluated 24 neonates. The median score attributed to neonatal pain during the heel prick was 7.0 (Interquartile range: 5-8). Compared to pre-, in the post-periods, more pediatricians fixed their gaze on the lower face (63 vs. 92%; p=0.036) and the number of visual fixations was greater on the lower face (2.0 vs. 5.0; p=0.018). There was no difference in the number and time of visual fixations according to the intensity of pain. CONCLUSIONS: At bedside, pediatricians change their focus of attention on the neonatal face after a painful procedure, focusing mainly on the lower part of the face.

Modified biplanar (0-90°) endoscopic-guided puncture technique for percutaneous nephrolithtomy: refinement with endoscopic combined intrarrenal surgery to reduce fluoroscopy and operative time.

INTRODUCTION: We aim to publish our innovative modified biplanar 0-90 endoscopic guided puncture technique for percutaneous nephrolithotomy in supine recorded with a GoPro® camera for standardization of the technique. It solves drawbacks of the fluoroscopic technique, i.e., in kidneys with complex anatomy, it may be challenging to distinguish calyces as they are often superposed, and it does not allow for all benefits of a combined endoscopic approach (1, 2). Our technique shortens puncture and fluoroscopic time and is easy to teach and reproduce. METHODS: A 77-year-old female patient had previous double J insertion due to an obstructing stone in the right distal ureter. She managed to pass the distal stone but remained with the double J and a 20mm stone (1300HU) in the right renal pelvis. The shared decision was for the actual standard of care (3, 4) endoscopic combined intrarenal surgery (ECIRS). The MiniECIRS started with flexible ureteroscopy and a posterior calix which gave direct access to the stone was chosen. The tip of the flexible scope was used to mark point A with the C-arm in the 0-degree position and line B in the 90-degree position. Puncture was fast and the MiniECIRS was uneventful with a single mid-pole access guided by the flexible scope. The surgeon had a Full-HD GoPro® camera mounted on his head, controlled by the surgical staff. All essential surgical steps were recorded. RESULTS: The quality of the recorded movie was graded as excellent, and the camera did not cause any discomfort to the surgeon. Operative and X-Ray time were 120minutes and 2minutes (7.64mGy). Hemoglobin drop was 0.8g/dL. The post-operative day-1 computed tomography scan was stone-free. The patient was discharged 24h after surgery. Kidney stent was left with a string and removed after 5days. The patient remained asymptomatic and metabolic evaluation revealed a calcium oxalate stone, low urinary volume and hypocitraturia which were treated with potassium citrate and hydration. CONCLUSION: The Modified Biplanar (0-90 degree) Endoscopic-Guided Puncture Technique for Percutaneous Nephrolithotomy joins the reproducibility of the same technique under fluoroscopy with advantages regarding safety and efficiency of ECIRS.

Artisanal model replaces animal use for ultrasound-guided fine needle puncture practice in medical sciences teaching.

Fine needle puncture (FNP) is a widespread technique used to collect cellular samples. Its efficiency can be enhanced by the use of ultrasonography to guide the procedure. Ultrasound-guided FNP is therefore an operator-dependent exam. For this reason, it demands the acquisition of psychomotor skill, ability to recognize structures, and dexterity during the needle puncture. This study describes the development of an artisanal simulator made with gelatin to replace the use of live animals during practical classes in veterinary or medical sciences education. The experimental set consisted of three phases in which the student performed different tasks such as recognition of the target structure with ultrasound and injection of ink (phase 1) or aspiration (phase 2) of its content and evaluation of a parenchymatous organ (liver) and puncture of its surface (phase 3). A survey on the acceptance of the model was carried out, and students filled out a questionnaire elaborated with the visual analog scale system. Participants considered the artisanal model a strong method to teach ultrasound-guided FNP. Other attractive advantages of this simulator are the low manufacturing costs (compared with expensive high-technology devices) and the possibility to replace the use of live animals in practical classes.NEW & NOTEWORTHY This study describes an artisanal simulator made with gelatin to teach ultrasound-guided fine needle puncture during practical classes in veterinary or medical sciences education. A three-phase experimental set allowed the students to practice ultrasound-guided fine needle puncture, aspiration, and injection in three different target structures. This cost-effective simulator may be an alternative to the use of expensive devices or the use of live animals during practical classes.

Punción ventricular transorbitaria: Revisión de la técnica y reporte de un caso / Transorbital Ventricular Puncture: Review of the technique and report of a case

La punción ventricular transorbitaria (PTO) es una técnica rápida y sencilla aunque poco utilizada en la actualidad. Como puede realizarse en la cama del paciente, resulta ideal en aquellos con hidrocefalia aguda rápidamente evolutiva o con enclavamiento transtentorial inminente o reciente, en quienes el acceso expeditivo a las cavidades ventriculares puede salvarles la vida. Revisamos aquí el desarrollo histórico de la técnica desde su descripción original en 1933. Por último, presentamos el caso de una paciente con hidrocefalia aguda secundaria a edema cerebeloso, en quien el empleo de la PTO dio tiempo para implementar el tratamiento definitivo. La técnica utilizada por nosotros consistió en un ingreso transpalpebral, por detrás del reborde orbitario superior y a nivel mediopupilar, con una trayectoria dirigida hacia la sutura sagital, dos a tres traveses de dedo por detrás de la sutura coronal(AU)

Transorbital ventricular puncture (TOP) is a fast and simple but poorly understood technique. As it can be performed at the patient's bedside, it is ideal in patients with rapidly evolving acute hydrocephalus or with imminent or recent transtentorial herniation, in whom expeditious access to the ventricular cavities can be life-saving. We review the historical development of the technique since its original description in 1933. Finally we present the case of a patient with acute hydrocephalus secondary to cerebellar edema, in whom the use of TOP allowed time to implement definitive treatments. The technique used by us consisted of an entry point through the upper eyelid, behind the superior orbital rim, and at the midpupillary line, with a trajectory aimed towards the sagittal suture two to three finger widths behind the coronal suture(AU)

Manual and alternative therapies as non-pharmacological interventions for pain and stress control in newborns: a systematic review.

BACKGROUND: Supporting therapies that provide stress and pain control of preterm and term newborns infants contribute positively to the neuropsychomotor development. Non-pharmacological interventions that involve manual techniques are described, considering protocols that can be reproduced by physical therapists, with positive and negative outcomes reports. DATA SOURCES: Systematic review follows PRISMA 2020 statements guidelines. Primary and specific health sciences databases (Science Direct, Pubmed, Scielo, Embase and Scopus) were consulted between October 2021 and May 2022. Articles considered were clinical trials, randomized or not, that included descriptions of the type of intervention as non-pharmacological and that studied the following outcomes: "pain" and "stress". RESULTS: Fifteen articles were selected for analysis, reaching a methodological quality of at least 3 on the Jadad Scale for the Quality of Researched Sources. The non-pharmacological therapies most applied in isolation were massage, swaddling or wrapping, gentle touch and kinesthetic stimulation, and the combined therapies were non-nutritive sucking and swaddling, oral sucrose and swaddling, sensory stimulation and familiar odors, and sensory saturation. The outcomes found were relaxation, pain, and stress reduction after the application of painful procedures. The behavioral changes included crying, grimacing, yawning, sneezing, jerky arm or leg movements, startles, and finger flaring. The vital signs included heart rate, blood oxygen saturation level, and pulse respiration. CONCLUSIONS: Combined techniques lead to better results in controlling neonatal pain when compared to isolated techniques. They can be applied both in preterm and term infants in a safe way and are reproducible in any health unit in a simple and economical way.

Gestión del capital venoso de los recién nacidos hospitalizados: catéter de línea media (CM) con técnica adaptada. Servicio de Neonatología, Hospital Público de Chile / Venous capital management of hospitalized newborns: midline catheter (MC) with adapted technique. Neonatology Service, Chilean public hospital

INTRODUCCIÓN: El catéter midline o de línea media (CM) es un dispositivo de acceso vascular que mide de 6 a 20cm, con la punta del dispositivo ubicado en venas basílica, braquial o cefálica debajo del pliegue axilar. El catéter de línea media se caracteriza por ser un acceso confiable y proporcionar menores complicaciones que un catéter intravenoso periférico corto. Este tipo de dispositivo vascular se ha utilizado ampliamente en adultos, pero faltan estudios desarrollados en el área neonatal. OBJETIVO: fue describir las características de la utilización de catéter midline con técnica adaptada en recién nacidos hospitalizados con necesidad de terapia intravascular en un hospital público de Chile, durante 2 años de seguimiento. METODOLOGÍA: Investigación descriptiva y retrospectiva, estuvo orientada a la identificación de las variables relacionadas a: tiempo de permanencia, características de la terapia intravascular, sitio de inserción, complicaciones y causa de retiro. RESULTADOS: La muestra estuvo conformada por 163 usuarios entre 24 y 41 semanas de edad gestacional, peso de nacimiento en un rango de 500 y 4880 gramos. El 87,7% se retiró por término de tratamiento intravascular, mientras que el 12,3% del total de los CM presentó complicaciones. El promedio de rendimiento del CM fue de 7,99 días, el sitio de inserción más frecuente correspondió a extremidad superior derecha, mientras que su utilización estuvo dada principalmente para fleboterapia, antibióticos y nutrición parenteral periférica. CONCLUSIÓN: Se concluye que el CM con técnica adaptada en usuarios neonatales presenta una alta tasa de éxito para completar la terapia intravascular periférica y bajo porcentaje de complicaciones.

INTRODUCTION: The midline catheter (MC) is a vascular access device measuring 6 to 20cm, with the tip of the device located in the basilic, brachial or cephalic veins below the axillary crease. The midline catheter is characterized as a reliable access and provides fewer complications than a short peripheral intravenous catheter. This type of vascular device has been widely used in adults, but studies developed in the neonatal area are lacking. OBJECTIVE: to describe the characteristics of the use of midline catheter with adapted technique in hospitalized newborns in need of intravascular therapy in a public hospital in Chile, during 2 years of follow-up. METHODOLOGY: Descriptive and retrospective research was oriented to the identification of variables related to: length of stay, characteristics of intravascular therapy, site of insertion, complications and cause of withdrawal. RESULTS: The sample consisted of 163 users between 24 and 41 weeks of gestational age, birth weight in the range of 500 and 4880 grams.

Método de punção guiada por ultrassom no diagnóstico de hematoma de barbela em bovino - relato de caso / Ultrasound-guided puncture method in the diagnosis of dewlap hematoma in bovine - case report / Método de punción por ultrasonidos en el diagnóstico del hematoma de papadas en bovinos - informe de uncaso

Injúrias relacionadas a interação animal/estrutura podem ser encontradas em sistema de confinamento Free-Stall. O hematoma de barbela pode estar relacionado a uma lesãoporcontato sofrido pelo animal com o tronco limitador da cama do Free-Stall no momentoemque ele deita para descansar. O objetivo do presente relato é descrever ummétododediagnóstico e tratamento utilizado em uma fêmea leiteira que apresentou aumento de volumelocalizado na região da barbela. Um bovino ½ HZ, fêmea, primípara, comaproximadamente60 dias em lactação (DEL), acomodada em sistema de confinamento Free-Stall e provenientede fazenda localizada no município de Lavras ­ MG apresentou aumento de volume na regiãoda barbela, sem mais nenhuma manifestação clínica. Durante o exame físico, identificou-seapresença de líquido na região edemaciada da barbela, próximo a região do peito. Foi realizadoexame ultrassonográfico e descartada a presença de pus. Com isso, foi feita uma punçãoguiada por ultrassom no local e confirmado a presença de sangue. Comesses resultados, confirmou-se o diagnóstico de hematoma e determinou-se a etiologia: lesão de contatodoanimal com o limitador da contenção da cama. Foi realizado o tratamento e houverecuperação significativa do animal. A punção guiada por ultrassomproporcionouaverificação da composição do líquido e comprovou a utilidade do exame ultrassonográfico, que foi de extrema importância para o relato.(AU)

Injuries related to animal/structure interaction can be found in Free-Stall confinement systems. The dewlap hematoma may be related to an injury caused by contact suffered by the animal with the restraint structure of the Free-Stall's liyng when it lies down to rest. The objectiveofthe present report is to describe a method of diagnosis and treatment used in a dairy cattle that presented an increase in volume located in the region of the dewlap. A primiparous female ½ HZ cow, with approximately 60 days in milk (DIM), accommodated in a Free-Stall confinement system and coming from a farm located in the municipality of Lavras - MG, presented an increase in volume in the dewlap region, without any further clinical manifestation. During the physical exam, the presence of fluid was identified in the swollenregion of the dewlap, close to the chest region. Ultrasound examination was performedandthe presence of pus was ruled out. Thus, an ultrasound-guided puncture was performedat thesite and the presence of blood was confirmed. With these results, the diagnosis of hematomawas confirmed and the etiology was determined: contact injury of the animal with the restraint structure of the lying. The treatment was carried out and there was a significant recoveryofthe animal. The ultrasound-guided puncture provided the verification of the liquidcomposition and proved the utility of the ultrasound examination, which was extremely important for this report.(AU)

Massage for pain relief in newborns submitted to puncture: systematic review.

OBJECTIVE: To analyze in the scientific literature the effects of massage on pain relief in newborns submitted to puncture. METHOD: Systematic review with meta-analysis performed in October 2020, using PubMed, Web of Science, CINAHL, Scopus, Cochrane and Gale databases. Studies without time frame were included, which used massage as the main technique for relieving neonatal pain during puncture. Data were extracted using standardized forms and the synthesis of results occurred in a descriptive way. RESULTS: From the 12 studies included, massage was effective in pain relief in 83.3% of the studies. The comparative meta-analysis of massage versus routine care that assessed duration of crying obtained a statistically significant result (p = 0.0002; 95% CI -85.51 to -27.09). CONCLUSION: Massage contributes to neonatal pain relief by reducing pain score and reducing crying time in newborns submitted to puncture.

Glucose and reflexology for pain relief during arterial puncture in neonates: a protocol.

OBJECTIVE: To present a study protocol to compare glucose and reflexology in pain relief in neonate intensive care during arterial punctures. METHODS: A randomized, controlled, double-blind clinical trial protocol will be carried out at a teaching hospital maternity, with30 newborns admitted to neonate intensive care who are to undergo blood collection by arterial puncture. They will be randomly assigned to a control group (25% glucose) or an intervention group (foot reflexology). The primary outcome will be neonate pain scores during and after arterial puncture. Secondary outcomes will be crying time and variation in neonates' vital signs during and after the arterial puncture procedure. Registration number RBR-639bff. DISCUSSION: The results of this trial will provide new insights into the most appropriate intervention for the relief of neonate pain during painful procedures.
