Abstract
Cancer pain seriously reduces the quality of life of cancer patients. However, most research about cancer focuses solely on inhibiting tumor growth, neglecting the issue of cancer pain. Therefore, the development of therapeutic agents with both tumor suppression and cancer pain relief is crucial to achieve human-centered treatment. Here, the work reports curcumin (CUR) and ropivacaine (Ropi) coincorporating CaCO3/PDA nanoparticles (CaPNMCUR+Ropi) that realized efficient tumor immunotherapy and cancer pain suppression. The therapeutic efficiency and mechanism are revealed in vitro and in vivo. The results indicate that CaPNMCUR+Ropi underwent tumor microenvironment-responsive degradation and realized rapid release of calcium ions, Ropi, and CUR. The excessive intracellular calcium triggered the apoptosis of tumor cells, and the transient pain caused by the tumor injection was relieved by Ropi. Simultaneously, CUR reduced the levels of immunosuppressive factor (TGF-β) and inflammatory factor (IL-6, IL-1β, and TNF-α) in the tumor microenvironment, thereby continuously augmenting the immune response and alleviating inflammatory pain of cancer animals. Meanwhile, the decrease of TGF-β leads to the reduction of transient receptor potential vanilloid 1 (TRPV1) expression, thereby alleviating hyperalgesia and achieving long-lasting analgesic effects. The design of the nanosystem provides a novel idea for human-centered tumor treatment in the future.

Zhang L, Yang L, Lei X, Dong W, Zhang L. Pain-related changes in crSO 2 among premature infants undergoing PICC insertion. J Matern Fetal Neonatal Med 2023; 36:2241976. [PMID: 37527965 DOI: 10.1080/14767058.2023.2241976] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Revised: 07/14/2023] [Accepted: 07/24/2023] [Indexed: 08/03/2023]
Abstract
OBJECTIVE To evaluate the effectiveness of cerebral regional oxygen saturation (crSO2) values, measured using near-infrared spectroscopy (NIRS), in assessing pain associated with the peripherally inserted central catheter (PICC) in premature infants. METHODS NIRS was used to measure the crSO2 levels of 48 premature infants with gestational age (GA) of < 32 weeks or a birth weight of < 1500 g. Premature infant pain profile (PIPP) scores, vital signs, transcutaneous oxygen tension (TcpO2), transcutaneous carbon dioxide tension (TcpCO2), and crSO2 values were monitored. One-way repeated measure analysis of variance was used to compare heart rate (HR), respiratory rate (RR), blood pressure (BP), peripheral oxygen saturation (SpO2), TcpO2, TcpCO2, and crSO2 values before (Time 1), during (Time 2), and after (Time 3) PICC insertion. The correlation between the PIPP scores at Time 2 and the fluctuations (values detected at Time 2 minus those at Time 1) of SpO2, TcpO2, and crSO2 were also analyzed. RESULTS The PIPP score at Time 2 was significantly higher than those at Times 1 and 3. HR, RR, and BP values increased (p < .05), and SpO2 and crSO2 levels decreased at Time 2 (p < .05) compared with those at Time 1. Stratified analysis based on GA revealed significant differences in HR, RR, and crSO2 values between Times 1 and 2 in infants with a GA of ≥ 32 weeks. In infants with a GA < 32 weeks, significant differences were observed in HR, RR, SpO2, BP, and crSO2 values between Times 1 and 2. The fluctuation of the crSO2 level was strongly correlated with the PIPP score at Time 2 (r = -0.829, p < .001). A weak correlation was observed between the PIPP score at Time 2 and TcpO2 level fluctuation (r = 0.375, p = .009). No correlation was observed between the PIPP score at Time 2 and SpO2 level fluctuation (r = 0.242, p = .097). CONCLUSION The fluctuation of crSO2 levels strongly correlates with PICC procedural pain. Hence, crSO2 levels measured using NIRS may be used as an indicator for pain assessment in premature infants.

Abstract
BACKGROUND Avoiding anesthesia for infant peripherally inserted central catheter insertion beyond the neonatal period has been the subject of very little research despite this being a high-risk age group. In our institution, we introduced a "Fast, Feed, and Wrap" technique, previously described for magnetic resonance imaging scans, for infants up to 6 months and weighing under 5.5 kg undergoing peripherally inserted central catheter insertion. AIMS The aim was to report our experience using "Fast, Feed, and Wrap," in particular the success rate and proportion of qualifying infants who were managed this way. METHODS A retrospective study was undertaken using electronic records and case notes to determine patient age, weight, indication for procedure, anesthetic technique (general anesthesia or "Fast, Feed, and Wrap"), peripherally inserted central catheter details (site of insertion, gauge, and number of lumens), and length of procedure. RESULTS Fifty-one infants qualified for "Fast, Feed, and Wrap" over a 42-month period, 43 were attempted this way and 40 were successful. All infants were greater than 40 weeks postconceptual age at the time of peripherally inserted central catheter insertion under "Fast, Feed, and Wrap," though 26% were preterm. The average age of babies undergoing "Fast, Feed, and Wrap" was 35 days (IQR 18-55), and the median weight was 3.78 kg (IQR 3.48-4.77). CONCLUSIONS Infants younger than 6 months and under 5.5 kg can be managed without general anesthesia for peripherally inserted central catheter insertion using a Fast, Feed, and Wrap technique.

Abstract
Topical anesthetic agent causes transient insensibility to pain in a limited area of skin, and provides effective anesthesia in a short onset time, short duration, with seldom local or systemic side effects on intact skin and is simple to use. Topical formulations may offer significant benefits for prevention of procedural pain. Currently, they are considered to be the most effective anesthesia for laser treatments. Unfortunately, there is no standard anesthetic technique for this procedure. Lasers are being widely used in numerous dermatological and esthetics treatments in childhood. The advancement of new knowledge in laser technology have contributed to the development of new lasers that are commonly used in a pediatric population, such as Pulsed Dye, Carbon-dioxide and Nd:YAG laser. The most commonly used topical anesthetics in young patients for minimally or moderately painful laser cutaneous procedures are Lidocaine, Prilocaine, Tetracaine gel and combinations thereof.

Abstract
AIM We compared the effect of two different doses of sucrose on neonatal pain scores during venepuncture. METHODS This randomised crossover study focused on neonates born weighing more than 1000 g from December 2014 to June 2016, who received neonatal intensive care at two hospitals: one in Empangeni, South Africa, and one in Trondheim, Norway. During two consecutive venepuncture procedures, 27 neonates from South Africa and 26 neonates from Norway were randomised to receive 0.2 mL or 0.5 mL sucrose. Half was administered two minutes before venepuncture and the rest immediately before the procedure. South Africa used 25% sucrose and Norway 24%. Pain scores were measured twice using the Premature Infant Pain Profile-Revised: during skin puncture and after the needle was removed. RESULTS The mean pain scores during skin puncture were significantly lower with 0.5 mL sucrose than with 0.2 mL (5.3 versus 6.8, p=0.008), but the mean pain scores after the needle was removed were similar with both doses (4.7 versus 5.4, p=0.29). We found no significant association between weight and pain scores. CONCLUSION We showed that neonates received better pain relief from 0.5 mL than 0.2 mL sucrose during venepuncture but not after the needle was removed.

Abstract
Pain in infants is undertreated and poorly understood, representing a major clinical problem. In part, this is due to our inability to objectively measure pain in nonverbal populations. We present and validate an electroencephalography-based measure of infant nociceptive brain activity that is evoked by acute noxious stimulation and is sensitive to analgesic modulation. This measure should be valuable both for mechanistic investigations and for testing analgesic efficacy in the infant population.

Abstract
BACKGROUND Randomized controlled trials evaluate the effectiveness of interventions for central venous access devices, however, high complication rates remain. Scoping reviews map the available evidence and demonstrate evidence deficiencies to focus ongoing research priorities. METHOD A scoping review (January 2006-December 2015) of randomized controlled trials evaluating the effectiveness of interventions to improve central venous access device outcomes; including peripherally inserted central catheters, non-tunneled, tunneled and totally implanted venous access catheters. MeSH terms were used to undertake a systematic search with data extracted by two independent researchers, using a standardized data extraction form. RESULTS In total, 178 trials were included (78 non-tunneled [44%]; 40 peripherally inserted central catheters [22%]; 20 totally implanted [11%]; 12 tunneled [6%]; 6 non-specified [3%]; and 22 combined device trials [12%]). There were 119 trials (68%) involving adult participants only, with 18 (9%) pediatric and 20 (11%) neonatal trials. Insertion-related themes existed in 38% of trials (67 RCTs), 35 RCTs (20%) related to post-insertion patency, with fewer trials on infection prevention (15 RCTs, 8%), education (14RCTs, 8%), and dressing and securement (12 RCTs, 7%). There were 46 different study outcomes reported, with the most common being infection outcomes (161 outcomes; 37%), with divergent definitions used for catheter-related bloodstream and other infections. CONCLUSION More high quality randomized trials across central venous access device management are necessary, especially in dressing and securement and patency. These can be encouraged by having more studies with multidisciplinary team involvement and consumer engagement. Additionally, there were extensive gaps within population sub-groups, particularly in tunneled devices, and in pediatrics and neonates. Finally, outcome definitions need to be unified for results to be meaningful and comparable across studies.

Abstract
BACKGROUND The availability of a safe and effective pharmacological therapy to reduce procedural pain in preterm infants is limited. The effective analgesic single dose of intravenous paracetamol in preterm infants is unknown. Comparative studies on efficacy of different paracetamol doses in preterm infants are lacking. OBJECTIVES To determine the analgesic effects of different single intravenous paracetamol doses on pain from peripherally inserted central catheter (PICC) placement in preterm infants. METHODS In a blinded randomized controlled trial, the analgesic effects of 10-, 15-, and 20-mg/kg single-dose intravenous paracetamol before PICC placement were compared in neonates with a gestational age <32 weeks. Secondly, a separate age-matched nonrandomized control group receiving oral sucrose was included. Pain was assessed with the Premature Infant Pain Profile (PIPP) and the COMFORTneo score. Peak plasma concentrations of paracetamol were determined. RESULTS A total of 60 patients were included in the paracetamol dose groups (median gestational age = 27.8, IQR: 25.7-29.2 weeks). PIPP scores were comparable: median = 8 (IQR: 6-10.5), 7 (IQR: 6-9), and 8 (IQR: 6-10) for the 10-, 15-, and 20-mg/kg paracetamol groups, respectively (p = 0.94). COMFORTneo scores were not statistically different between the different paracetamol dose groups (p = 0.35). All randomized subjects, except for 3 who received 10 mg/kg of paracetamol, had peak paracetamol concentrations >9 mg/L. PIPP (p = 0.78) and COMFORTneo (p = 0.08) scores were also comparable between paracetamol- and sucrose-treated patients. CONCLUSIONS We found no analgesic benefit from intravenous paracetamol studied in different single doses over sucrose for PICC placement in preterm infants. Paracetamol is not a suitable analgesic for this procedure in preterm infants.

Abstract
BACKGROUND Administration of oral sucrose with and without non-nutritive sucking is the most frequently studied non-pharmacological intervention for procedural pain relief in neonates. OBJECTIVES To determine the efficacy, effect of dose, method of administration and safety of sucrose for relieving procedural pain in neonates as assessed by validated composite pain scores, physiological pain indicators (heart rate, respiratory rate, saturation of peripheral oxygen in the blood, transcutaneous oxygen and carbon dioxide (gas exchange measured across the skin - TcpO2, TcpCO2), near infrared spectroscopy (NIRS), electroencephalogram (EEG), or behavioural pain indicators (cry duration, proportion of time crying, proportion of time facial actions (e.g. grimace) are present), or a combination of these and long-term neurodevelopmental outcomes. SEARCH METHODS We used the standard methods of the Cochrane Neonatal. We performed electronic and manual literature searches in February 2016 for published randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library, Issue 1, 2016), MEDLINE (1950 to 2016), EMBASE (1980 to 2016), and CINAHL (1982 to 2016). We did not impose language restrictions. SELECTION CRITERIA RCTs in which term or preterm neonates (postnatal age maximum of 28 days after reaching 40 weeks' postmenstrual age), or both, received sucrose for procedural pain. Control interventions included no treatment, water, glucose, breast milk, breastfeeding, local anaesthetic, pacifier, positioning/containing or acupuncture. DATA COLLECTION AND ANALYSIS Our main outcome measures were composite pain scores (including a combination of behavioural, physiological and contextual indicators). Secondary outcomes included separate physiological and behavioural pain indicators. We reported a mean difference (MD) or weighted MD (WMD) with 95% confidence intervals (CI) using the fixed-effect model for continuous outcome measures. For categorical data we used risk ratio (RR) and risk difference. We assessed heterogeneity by the I(2) test. We assessed the risk of bias of included trials using the Cochrane 'Risk of bias' tool, and assessed the quality of the evidence using the GRADE system. MAIN RESULTS Seventy-four studies enrolling 7049 infants were included. Results from only a few studies could be combined in meta-analyses and for most analyses the GRADE assessments indicated low- or moderate-quality evidence. There was high-quality evidence for the beneficial effect of sucrose (24%) with non-nutritive sucking (pacifier dipped in sucrose) or 0.5 mL of sucrose orally in preterm and term infants: Premature Infant Pain Profile (PIPP) 30 s after heel lance WMD -1.70 (95% CI -2.13 to -1.26; I(2) = 0% (no heterogeneity); 3 studies, n = 278); PIPP 60 s after heel lance WMD -2.14 (95% CI -3.34 to -0.94; I(2) = 0% (no heterogeneity; 2 studies, n = 164). There was high-quality evidence for the use of 2 mL 24% sucrose prior to venipuncture: PIPP during venipuncture WMD -2.79 (95% CI -3.76 to -1.83; I(2) = 0% (no heterogeneity; 2 groups in 1 study, n = 213); and intramuscular injections: PIPP during intramuscular injection WMD -1.05 (95% CI -1.98 to -0.12; I(2) = 0% (2 groups in 1 study, n = 232). Evidence from studies that could not be included in RevMan-analyses supported these findings. Reported adverse effects were minor and similar in the sucrose and control groups. Sucrose is not effective in reducing pain from circumcision. The effectiveness of sucrose for reducing pain/stress from other interventions such as arterial puncture, subcutaneous injection, insertion of nasogastric or orogastric tubes, bladder catherization, eye examinations and echocardiography examinations are inconclusive. Most trials indicated some benefit of sucrose use but that the evidence for other painful procedures is of lower quality as it is based on few studies of small sample sizes. The effects of sucrose on long-term neurodevelopmental outcomes are unknown. AUTHORS' CONCLUSIONS Sucrose is effective for reducing procedural pain from single events such as heel lance, venipuncture and intramuscular injection in both preterm and term infants. No serious side effects or harms have been documented with this intervention. We could not identify an optimal dose due to inconsistency in effective sucrose dosage among studies. Further investigation of repeated administration of sucrose in neonates is needed. There is some moderate-quality evidence that sucrose in combination with other non-pharmacological interventions such as non-nutritive sucking is more effective than sucrose alone, but more research of this and sucrose in combination with pharmacological interventions is needed. Sucrose use in extremely preterm, unstable, ventilated (or a combination of these) neonates needs to be addressed. Additional research is needed to determine the minimally effective dose of sucrose during a single painful procedure and the effect of repeated sucrose administration on immediate (pain intensity) and long-term (neurodevelopmental) outcomes.

Abstract
The past several years have seen an increased appreciation of the potential role of the endocrine system in the recovery process following surgery for congenital heart disease. Many of the hormonal changes following cardiac surgery are adaptive and necessary, whereas activation of proinflammatory cytokine and chemokine responses and some of the metabolic changes following surgery are likely mediators leading to detrimental outcomes. Additionally, other hormonal perturbations may contribute to adverse outcomes. This review examines the pain and the stress response, thyroid function and hyperglycemia following cardiopulmonary bypass (CPB), and the potential role of corticosteroids in the pediatric cardiac critical care unit.

Abstract
BACKGROUND Administration of oral sucrose with and without non-nutritive sucking is the most frequently studied non-pharmacological intervention for procedural pain relief in neonates. OBJECTIVES To determine the efficacy, effect of dose and safety of oral sucrose for relieving procedural pain in neonates. SEARCH METHODS We used the standard methods of the Cochrane Neonatal Review Group. Electronic and manual searches were performed in November 2011 for published randomised controlled trials (RCTs) in MEDLINE (1950 to November 2011), EMBASE (1980 to 2011), CINAHL (1982 to November 2011) and the Cochrane Central Register of Controlled Trials (The Cochrane Library). We did not impose language restrictions. SELECTION CRITERIA RCTs in which term, preterm, or both term and preterm neonates (postnatal age maximum of 28 days after reaching 40 weeks' postmenstrual age) received sucrose for procedural pain. Control conditions included no treatment, water, pacifier, positioning/containing or breastfeeding. DATA COLLECTION AND ANALYSIS Main outcome measures were physiological, behavioural, or both pain indicators with or without composite pain scores. A mean difference (MD) with 95% confidence intervals (CI) using the fixed-effect model was reported for continuous outcome measures. Trial quality was assessed as per The Cochrane Collaboration MAIN RESULTS Fifty-seven studies enrolling 4730 infants were included. Results from only a few studies could be combined in meta-analyses. When Premature Infant Pain Profile (PIPP) scores were pooled, sucrose groups had significantly lower scores at 30 seconds (weighted mean difference (WMD) -1.76; 95% CI -2.54 to - 0.97; 4 trials; 264 neonates] and 60 seconds (WMD -2.05; 95% CI -3.08 to -1.02; 3 trials' 195 neonates) post-heel lance. For retinopathy of prematurity (ROP) examinations, sucrose did not significantly reduce PIPP scores (WMD -0.65; 95% CI -1.88 to 0.59; 3 trials; 82 neonates). There were no differences in adverse effects between sucrose and control groups. Sucrose significantly reduced duration of total crying time (WMD -39 seconds; 95% CI -44 to -34; 2 trials; 88 neonates), but did not reduce duration of first cry during heel lance (WMD -9 seconds; 95% CI -20 to 2; 3 trials; 192 neonates). Oxygen saturation (%) was significantly lower in infants given sucrose during ROP examination compared to controls (WMD -2.6; 95% CI -4.9 to - 0.2; 2 trials; 62 neonates). Results of individual trials that could not be incorporated in meta-analyses supported these findings. The effects of sucrose on long-term neurodevelopmental outcomes are unknown. AUTHORS' CONCLUSIONS Sucrose is safe and effective for reducing procedural pain from single events. An optimal dose could not be identified due to inconsistency in effective sucrose dosage among studies. Further investigation on repeated administration of sucrose in neonates and the use of sucrose in combination with other non-pharmacological and pharmacological interventions is needed. Sucrose use in extremely preterm, unstable, ventilated (or a combination of these) neonates needs to be addressed.

Abstract
O cateter central de inserção periférica é tecnologia comum empregada na terapia intravenosa de neonatos. Trata-se de revisão integrativa, cujo objetivo foi investigar e analisar as evidências disponíveis na literatura acerca da temática. As bases de dados pesquisadas foram Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Biblioteca Nacional de Medicina dos Estados Unidos (PubMed). Resultados apontam lacunas no que tange à população neonatal; conhecimento insuficiente dos profissionais quanto indicações (n=1); e variados temas sobre uso de anticoagulantes (n=6), comparação com outros cateteres (n=4), diagnóstico por imagem (n=2), dor (n=2), infecção relacionada a cateter e sua prevenção (n=7), entre outros fatores. Conclui-se que há necessidade de atualização profissional, evidências científicas de fácil acesso e publicações nacionais.

Abstract
OBJECTIVE To compare the efficacy and safety of sevoflurane deep sedation with glucose and nonnutritive sucking (GNNS) in reducing the duration of the procedure and in preventing pain-related effects during peripherally inserted central catheter (PICC) placement. BACKGROUND PICC placement in neonatal intensive care is a delicate and stressful procedure that requires pain prevention. GNNS has been recommended in this situation but remain often inefficient. METHODS We designed a randomized controlled study in a sixteen-bed pediatric and neonatal unit in a tertiary hospital. Fifty-nine neonates at >28 weeks of gestation with continuous positive airway pressure or invasive mechanical ventilation and requiring PICC placement were included. Patients were randomized to receive inhaled sevoflurane (IS) or glucose and non-nutritive sucking (GNNS). Procedural duration and conditions, hemodynamic and respiratory parameters, occurrence of movements and complications were compared (http://clinicaltrials.gov trial register no. NCT00420693). RESULTS The two groups had similar demographics. There were no between-group differences in procedural duration (P = 0.84) despite greater immobility in IS group (P = 0.017). IS was also associated with fewer episodes of hypertension (P = 0.003), tachycardia (P < 0.001), and bradycardia (P = 0.02). Occurrences of hypotension were not different between the groups (P = 0.06). The GNNS group showed more desaturation during the 4 h after the procedure (P = 0.03). Complications during intensive care stay did not differ between groups. CONCLUSION Inhaled sevoflurane does not make easier catheters placement but prevent pain-related symptoms. Because sevoflurane is responsible for hypotension, it requires careful monitoring and treatment adaptation.

SEARCH STRATEGY The standard methods of the Cochrane Neonatal Collaborative Review Group were used. SELECTION CRITERIA Randomized controlled trials in which term and/or preterm neonates (postnatal age maximum of 28 days corrected for postmenstrual age) received sucrose for procedural pain. Control conditions included water, pacifier, positioning/containing or breastfeeding. DATA COLLECTION AND ANALYSIS The main outcome measures were physiological and/or behavioural pain indicators and/or composite pain scores. A weighted mean difference (WMD) with 95% confidence intervals (CI) using the fixed effects model was reported for continuous outcome measures. MAIN RESULTS Forty-four studies enrolling 3,496 infants were included. Results from only a few studies could be combined in meta-analyses. Sucrose significantly reduced duration of total crying time (seconds) [WMD -39.26 (95% CI -44.29, -34.24), 88 neonates], but did not reduce duration of first cry (seconds) during heel lance [WMD -8.99 (95% CI -20.07, 2.10), 192 neonates]. No significant differences were found for percent change in heart rate from baseline at one minute [WMD 0.90 (95% CI -5.81, 7.61), 86 neonates] and three minutes [WMD -6.20 (95% CI -15.27, 2.88), 86 neonates] post-heel lance, or for mean heart rate at three minutes post-heel lance [WMD -0.98 (95% CI -8.29, 6.32), 154 neonates]. Oxygen saturation (%) was significantly lower in infants given sucrose during ROP examination compared to controls [WMD -2.58 (95% CI -4.94, - 0.23), 62 neonates]. Infants given sucrose post-heel lance had significantly lower PIPP scores at 30 seconds [WMD -1.64 (95% CI -2.47, - 0.81), 220 neonates] and 60 seconds [WMD -2.05 (95% CI -3.08, -1.02), 195 neonates]. For ROP exams, sucrose did not significantly reduce PIPP scores [WMD -0.65 (95% CI -1.88, 0.59), 82 neonates]. There were no differences in adverse effects between sucrose and control groups. AUTHORS' CONCLUSIONS Sucrose is safe and effective for reducing procedural pain from single events. An optimal dose could not be identified due to inconsistency in effective sucrose dosage among studies.Further investigation on repeated administration of sucrose in neonates and the use of sucrose in combination with other non-pharmacological (e.g. behavioural, physical) and pharmacologic interventions is needed. Sucrose use in extremely low birth-weight and unstable and/or ventilated neonates needs to be addressed.

Abstract
OBJETIVO: Dimensionar a dor durante a instalação do cateter central de inserção periférica, comparando o momento da punção venosa com a progressão do cateter. MÉTODOS: Estudo descritivo exploratório com coleta prospectiva dos dados realizado na unidade neonatal de um hospital-escola de grande porte da cidade de São Paulo. Avaliou-se a resposta dolorosa ao procedimento de inserção do cateter em 28 neonatos utilizando-se a escala Premature Infant Pain Profile (PIPP) nas etapas de pré-punção (15 segundos), punção venosa (30 segundos) e progressão do cateter (30 segundos). RESULTADOS: O escore PIPP maior ou igual a sete, indicativo de dor moderada a intensa, ocorreu em 13 RN (59,1%) na primeira punção venosa e 10 RN (45,5%) na progressão do cateter do grupo que não recebeu analgésico ou sedativo. CONCLUSÃO: Os resultados apontam para a necessidade de se adotar medidas analgésicas, uma vez que neonatos internados em unidade de terapia intensiva neonatal são freqüentemente submetidos a procedimentos invasivos e dolorosos.

Abstract
During the past two decades there has been a substantial increase in the number and types of topical anesthetics available. Options for the prevention of neonatal pain associated with skin-breaking procedures were previously limited to injections of lidocaine hydrochloride. Topical anesthetics are now available as creams, gels, and a heat-activated patch system. Although lidocaine injection continues to be widely used for pain associated with circumcision, lumbar puncture, or placement of central venous lines, practical information regarding the use of newer agents in the neonate is needed. This review seeks to expand the options for topical anesthesia in neonates.

Abstract
BACKGROUND Procedural pain relief is sub-optimal in neonates. Topical tetracaine provides pain relief in children. Evidence of its efficacy and safety in neonates is limited. The objective of this study was to assess the efficacy and safety of topical tetracaine on the pain response of neonates during a venipuncture. METHODS Medically stable infants greater than or equal to 24 weeks gestation, requiring a venipuncture, were included. Following randomization and double blinding, 1.1 g of tetracaine or placebo was applied to the skin for 30 minutes. Participants received oral sucrose if they met local eligibility criteria. The venipuncture was performed according to a standard protocol. A medium effect size in the pain score (corresponding to about 2 point difference in the PIPP score) was considered clinically significant, leading to a sample size of 142 infants, with 80% statistical power. Local skin reactions and immediate adverse cardiorespiratory events were noted. The primary outcome, PIPP score at 1 minute, was analysed using an independent Student's t-test. RESULTS One hundred and forty two infants were included, 33 +/- 4 weeks gestation, 2100 +/- 900 grams and 6 +/- 3 days of age. There was almost no difference in PIPP scores at 1 minute between groups (mean difference -0.09; 95% confidence interval [CI]: -1.68 to 1.50; P = . 91). Similarly, there were no differences in PIPP scores during the 2nd, 3rd and 4th minute. Duration of cry did not differ between the groups (median difference, 0; 95% CI, -3 to 0; P = . 84). The majority of infants in both groups received sucrose 24%. Sucrose had a significant effect on the PIPP score, as assessed by an ANOVA model (p = 0.0026). Local skin erythema was observed transiently in 11 infants (7 in the tetracaine and 4 in the placebo group). No serious side effect was observed. CONCLUSION Tetracaine did not significantly decrease procedural pain in infants undergoing a venipuncture, when used in combination with routine sucrose administration.
