Neonatal analgesia: A neglected issue in the tropics

Efficacy of Skin-to-Skin Care versus Swaddling for Pain Control Associated with Vitamin K Administration in Full-Term Neonates: A Randomized Controlled Trial

OBJECTIVE

The objective of the study was to assess the efficacy of immediate skin-to-skin care (SSC) versus swaddling in pain response to intramuscular injection of vitamin K at 30 min of birth in neonates.

METHODS

Healthy full-term newborns were enrolled immediately after normal vaginal delivery and randomized in two groups, SSC and swaddling. Neonatal Infant Pain Scale (NIPS) was measured before, immediately after and at 2 min after the injection.

RESULTS

Total 100 newborns were enrolled in the study (50 in each group). The mean (SD) birth weight of newborns in the SSC and swaddling group was 2668 (256) and 2730 (348) g, respectively. NIPS was comparable between the SSC and swaddling at before [1.78 (0.58) vs. 1.96 (0.83), p = 0.21], and immediately after the injection [4.82 (0.72) vs. 5.08 (0.75), p = 0.08]. NIPS at 2 min after the injection was significantly low in the SSC group compared to the swaddling group [1.38 (0.70) vs. 2.88 (1.00), p < 0.001]. At 2 min after injection, the NIPS score was significantly lower than baseline in the SSC group (p = 0.002), while it was significantly higher in the swaddling group (p < 0.001). A significantly higher proportion of newborns had a NIPS score of more than three at 2 min after injection in the swaddling group as compared to the SSC group (22% vs. 2%, p < 0.001).

CONCLUSION

Immediate SSC was more efficacious as compared to swaddling as a pain control intervention while giving vitamin K injection.

A comparison of anesthetic efficacy between dorsal penile nerve block (DPNB) with lidocaine and eutectic mixture of local anesthetics (EMLA) cream during neonatal circumcision

Objective

Circumcision is often performed in neonates and is associated with significant pain. This study was conducted to compare the anesthetic efficacy of two methods of local anaesthesia for neonatal circumcision: topical eutectic mixture of local anesthetics (EMLA) cream and dorsal penile nerve block (DPNB) with lidocaine.

Methods

Male neonates who presented for circumcision and met the eligibility criteria were recruited for the study and were randomly assigned to one of the two methods of anesthesia before the procedure. Anesthetic efficacy was compared by pain assessment during four standardized steps of the procedure (clamping, crushing, tying, and cutting of the foreskin, respectively) using the modified Neonatal Infant Pain Scale (NIPS), changes in transcutaneous oxygen saturation (SpO2), heart rate (HR), and preoperative and postoperative salivary cortisol levels. Patients also were evaluated after 24 hours to assess for complications.

Results

Totally, 138 babies were recruited. Significantly higher NIPS scores were observed among babies who had EMLA cream during tying (p=0.019) and cutting (p=0.043). The rise in mean HR from baseline was statistically significant throughout the procedure in the EMLA group. In the DPNB group, there was no significant rise in mean HR during crushing (p=0.919) and cutting (p=0.197). There was a significant decrease in mean SpO2 from baseline in both groups. Salivary cortisol showed significant increase in mean levels in both groups. No significant untoward effects were observed.

Conclusion

DPNB with lidocaine has a better pain control compared with EMLA cream during neonatal circumcision. Both methods are safe in neonates.

Effect of Expressed Breast Milk versus Swaddling versus Oral Sucrose Administration on Pain Associated with Suctioning in Preterm Neonates on Assisted Ventilation: A Randomized Controlled Trial

Objective:

The objective of our study was to assess the pain associated with suctioning in preterm neonates on assisted ventilation and comparing the use of expressed breast milk (EBM), sucrose, and swaddling to alleviate pain.

Methods:

Study design: A randomized controlled clinical trial.

Inclusion Criteria:

Preterm neonates on assisted ventilation.

Exclusion Criteria:

Major congenital anomalies and severe encephalopathy.

Study Duration and Site:

6 months in level III neonatal Intensive Care Unit. In the first phase, we used premature infant pain profile (PIPP) score to assess pain associated with suctioning in preterm neonates on assisted ventilation. In the second phase, the effect of EBM, swaddling, and sucrose on pain relief during suctioning in neonates on assisted ventilation was assessed.

Results:

There was a significant increase in pain associated with suctioning in preterm neonates on assisted ventilation (preprocedure PIPP score 7.90 ± 2.50; procedural PIPP score 13.63 ± 2.57; P < 0.05). The postintervention mean procedural PIPP score was not significantly different between the EBM, swaddling, and sucrose groups (P = 0.24).

Conclusions:

Suctioning is painful for preterm neonates on assisted ventilation. There was no difference between EBM, swaddling, and sucrose in relieving pain associated with suctioning.
