Ultrasound study of heel to calcaneum depth in neonates

AIM: To investigate whether it would be safe to extend the currently recommended area of sampling to the whole heel in neonates. METHODS: Eighty newborn infants were studied, weight range 0.56 to 4.34 kg, gestation 24 to 42 weeks. Ultrasound scanning was used to measure the shortest distance between the skin and the perichondrium of the calcaneum. RESULTS: The shortest depth of perichondrium was in the centre of the heel and ranged from 3 to 8 mm. In 78 of the 80 infants the distance was 4 mm or more. There was a small but significant positive correlation with weight. CONCLUSIONS: Standard automated lancets for preterm use that puncture to a depth of 2.4 mm may be safely used anywhere over the plantar surface of the heel. The posterior aspect of the heel should be avoided. Reducing the density of heel pricks should reduce the associated pain.     

Skin to calcaneus distance in the neonate

BACKGROUND: Current recommendations for obtaining blood from neonates advise avoidance of the midline area of the heel and are based on postmortem studies. OBJECTIVE: Because of the potential pain and tissue damage from repeated heel pricking in the same area, to investigate using ultrasonography whether the distance from skin to calcaneus is less at the midline than at the borders. METHODS: One hundred consecutive healthy preterm and 105 consecutive healthy term neonates were studied 48-72 hours after delivery. The skin to perichondrium distance (SPD) was measured on two occasions by ultrasound at the external, midline, and internal areas of the heel. FINDINGS: Mean SPD was 0.2 mm less at the midline than at the other sites. The proportion of measurements <3 mm at any of the three sites was the same. Depth was <3 mm in less than 3% of the term and approximately 20% of the preterm infants. The SPD correlated only with gestational age. Of children <33 weeks gestational age, 38% had an SPD <3 mm compared with 8% of older preterm infants. The proportions of preterm infants of > or = 33 weeks gestation and term infants with an SPD <3 mm were similar (8% v 3%). INTERPRETATION: With the use of automated lancets of 2.2 mm length or less, the whole heel plantar surface is safe for obtaining blood in term and preterm infants of > or = 33 weeks gestation. This means that soft tissue damage and pain from repeated pricking in the same area can be reduced.     

Plantar pressure measurement in children and youths during sports activities

The aim of this study was to consider whether changes occur in the foot area while under repeated physical stress and if they are age related. In addition it interests what consequences this might have in regard to proper shoe wear. The subjects for this study consisted of 15 children and youths aged between 4 and 16 years. The plantar pressure distribution and vertical ground reaction forces were measured before and after physical exercise. The subjects first ran a given distance wearing sport shoes, had a rest and then ran the same distance barefoot. The results showed marked age related differences after exercise. The pressure values were increased in all of the youths in the middle foot region. In comparison young children always exhibited an unbound gait pattern without any dynamic foot roll during heel strike or toe-off. The forefoot had ground contact from the beginning of the stance phase. To compensate for the lack of dynamic foot roll it is recommended that children wear a shoe with a soft sole and with sufficient space for toe movement. The sports shoe for youths should grip the heel and support the longitudinal arch to prevent an incorrect weight distribution.     

Soft Neurological Signs and EEG Pattern in Rural Malnourished Children

ABSTRACT. The present study was carried out in 208, 8–10 yr old male, rural, primary school children of Kashi Vidyapith Block, Varanasi. These children were examined for anthropometry, soft neurological signs and electroencephalographic pattern. It was found that the presence of soft neurological signs was related to the severity of malnutrition. The relationship between nutritional status and motor tasks showed that the performance in successive finger tapping, toe tapping, heel toe tapping, hand patting and alternating hand pronation supination in both hands while finger tapping with the right, was significantly affected. The EEG pattern in 16 children with soft neurological signs showed abnormalities in the form of slow and sharp waves, particularly in the frontal lobe, but also in the parietal and temporal lobes. The motor deficits were more marked on the contralateral side of the EEG abnormality.

Scald injury from the Guthrie test: should the heel be warmed?

A 6 day old boy sustained scalds to his right foot from application of a "warm nappy" to increase blood flow to facilitate heel pricking for a routine Guthrie test. It is proposed that active warming of the heel in isolation is not necessary in heel blood sampling.     

Serial neurologic examination of hyperactive children.

Forty-four of 102 children undergoing pharmacologic treatment of hyperactivity received serial neurologic examinations on five separate occasions. The responses to three of the "soft" neurologic signs administered were analyzed: heel gait, toe gait, and diadochokinesis. A high degree of variability of response within individuals was documented. There was no evidence of interaction between treatment and the subjects' responses. The degree of variability was such that to have used these data as measures of "improvement" (i.e., drug effect) would have been misleading. The value of these signs for purposes of diagnosis or assessment of therapy is doubtful.     

Can topical lignocaine reduce behavioural response to heel prick?

In a randomised, double blind, controlled study the ability of 5% lignocaine ointment to reduce the behavioural response to heel lance in 30 healthy neonates was assessed. Five per cent lignocaine ointment applied to the heel under an occlusive dressing for one hour before heel prick did not reduce the infants'' behavioural response to the heel prick procedure.     

Prior leg massage decreases pain responses to heel stick in preterm babies

AIM: Leg massage could inhibit the transmission of pain by 'closing the gate' or by activating the endogenous opioid pathway to decrease nociceptive transmission of pain associated with heel stick. The aim of this study is to determine the effects of massage therapy prior to heel stick on responses assessed by the Neonatal Infant Pain Scale (NIPS) (primary outcome), heart rate, respiratory rate and oxygen saturation (secondary outcomes) in infants who required a heel stick for blood sampling. METHODS: This randomised, double-blind, crossover trial with infants from 1 to 7 days post birth excluded those with prior surgery, septicaemia, current assisted ventilation or an analgesic within 48 h. After informed consent, 13 infants received a 2-min massage of the ipsilateral leg prior to heel stick on the first study sampling and no massage on the next sampling 2-7 days later and 10 infants had the reverse order. The bedside nurse, blinded to the intervention, measured NIPS, heart rate, respiratory rate, and oxygen saturation prior to massage, after massage, and 5 min after heel stick. Serum cortisol was measured with the blood sampling. RESULTS: In 23 infants (birthweight 795-2507 g), there were no adverse physiologic effects of massage. After heel stick, NIPS (P < 0.001) and heart rate (P = 0.03) were increased in the no-massage group compared with the massage group. Respiratory rate, oxygen saturation and serum cortisol were not significantly different. CONCLUSION: Gentle massage of the leg prior to heel stick is safe and decreases pain responses in preterm infants.     

Neonatal pain response to heel stick vs venepuncture for routine blood sampling

Neonatal pain response and adverse effects and maternal anxiety were assessed in 27 infants who were randomly allocated to venepuncture or heel stick. Pain was assessed by nurses using the Neonatal Infant Pain Scale (NIPS) and a three point scale for the mothers. NIPS scores were higher in the heel stick group compared with the venepuncture group. Maternal anxiety was higher before the procedure while perception of an infant''s pain was lower in the venepuncture group compared with the heel stick group. Venepuncture is less painful than heel stick in newborn infants undergoing routine blood sampling.     

Late intraperitoneal posterior bladder wall perforation caused by loose percutaneous stamey suprapubic catheter

Late intraperitoneal perforation of the posterior bladder wall resulting from the use of percutaneous suprapubic cystostomy catheters has not been previously reported. We describe a case where a Stamey-type percutaneous tube was used that developed a late posterior bladder wall perforation. This complication is more likely to occur when the catheter is not tied in at skin level and securely taped, particularly when the catheter material is not soft. The underlying diseased bladder and the presence of infection contributed to the bladder injury. Teaching parents about catheter care following hospital discharge is important in order to prevent such complications.     

The calming effect of a familiar odor on full-term newborns

We assessed the effectiveness of an odor (familiar or unfamiliar) in soothing healthy full-term newborns undergoing a routine heel stick. Forty-four breast-fed newborns were randomly assigned to one of four groups: Before the heel stick, Group 1 was naturally familiarized with their mother's milk odor, Group 2 was familiarized with a vanilla smell, and Groups 3 and 4 did not receive any familiarization. During and after the heel stick, Group 1 was presented with their mother's milk odor, Group 2 was presented with the familiar vanilla, Group 3 was presented with an unfamiliar odor, and Group 4 was a control group. Infants' crying, grimacing, and head movements were analyzed before, during, and after the heel stick. Results show that infants who smelled a familiar odor (their mother's milk or vanilla) cried and grimaced significantly less during the recovery phase compared with the heel stick phase. Infants who were presented with an unfamiliar odor or no odor showed no significant changes during recovery. Moreover, infants who smelled their mother's milk exhibited significantly less motor agitation during the heel stick compared with the other groups. These findings indicate that smelling a familiar odor reduces agitation during the heel stick and diminishes distress after the procedure.     

Food intake and oral sucrose in preterms prior to heel prick

To investigate the soothing effect of feeding on infants in distress, the effects of 2 mL 15% and 1 mL 25% sucrose given orally 2 min before heel prick in fasting preterms to reduce the pain response were assessed. The effects of milk intake by nasogastric tube were also assessed once during the last hour before heel prick, and the effects of milk intake by nasogastric tube once during the last hour before heel prick together with 1 mL 25% sucrose given orally 2 min before heel prick. The pain response was measured as changes in crying time, behavioural state, skin conductance and heart rate. Each group included 12 healthy preterm infants with a median gestational age of 32 wk and a median postnatal age of 14 d. These infants were randomly studied twice; one in connection with the intervention and once after being given sterilized water. Differences in the measured variables before and during heel prick showed that only the crying time was reduced when the infants received milk or 25% sucrose prior to heel prick (p < 0.05). If the infants received milk and 25% sucrose before heel prick, the crying time and the level of behavioural state were reduced (p < 0.05). The increase from before to during heel prick in skin conductance (number and amplitude of the waves) and heart rate correlated with the crying time (p < 0.01).     

Neonatal posterior fossa subdural hematoma

Hemorrhage into the posterior fossa is a rare neurosurgical emergency in neonates. CT scanning is diagnostic. Blood layering under the apex of the tentorium cerebelli, however, may resemble a dilated vascular structure, and the rigidity of the pressured tentorium may prevent upward transmission of increased intracranial pressure, resulting in a soft fontanelle.     

Intracranial pressure during procedural pain

Physiological changes provoked by pain may threaten the integrity of the CNS. In particular, intracranial pressure (ICP) regulates brain perfusion, and its sudden increase may trigger brain haemorrhage. We measured ICP in 51 healthy newborns (gestational age: 35-41 weeks) during blood sampling, by means of a tonometer applied to the anterior fontanelle. Peak ICP values were compared during 3 different types of blood sampling: from the external jugular vein (JV), by heel prick and by heel prick with sensorial saturation. Sensorial saturation consists in giving sensorial stimuli during pain to arrest the transmission of pain to the cerebral cortex. ICP peak values during heel prick were higher than during JV sampling (mean=26.22 vs. 21.036 mm Hg; p<0.0001), though babies who underwent the latter procedure had high ICP values before sampling due to the body position required. Heel prick with sensorial saturation was associated with a lower ICP peak (mean=11.75 mm Hg) than sampling from JV (p<0.0001). We concluded that heel prick caused a greater rise in ICP than sampling from JV and that sensorial saturation moderated the rise associated with heel prick.     

Effect of multisensory stimulation on analgesia in term neonates: a randomized controlled trial

Many attempts have been made to obtain safe and effective analgesia in newborns. Oral glucose-water has been found to have analgesic properties in neonates. We investigated whether other sensory stimulation added to oral glucose provided more effective analgesia than oral glucose alone. In a randomized prospective double-blind trial, we studied 120 term newborns during heel prick. The babies were divided randomly into six groups of 20, and each group was treated with a different procedure during heel prick: A) control; B) 1 mL 33% oral glucose given 2 min before the heel prick; C) sucking; D) 1 mL 33% oral glucose plus sucking; E) multisensory stimulation including 1 mL 33% oral glucose (sensorial saturation); F) multisensory stimulation without oral glucose. Sensorial saturation consisted in massage, voice, eye contact, and perfume smelling during heel prick. Each heel prick was filmed and assigned a point score according to the Douleur Aigu? du Nouveau-né (DAN) neonatal acute pain scale. Camera recording began 30 s before the heel prick, so it was impossible for the scorers to distinguish procedure A (control) from B (glucose given 2 min before), C (sucking water) from D (sucking glucose), and E (multisensory stimulation and glucose) from F (multisensory stimulation and water) from the video. Procedure E (multisensory stimulation and glucose) was found to be the most effective procedure, and the analgesia was even more effective than that produced by procedure D (sucking glucose). We conclude that sensorial saturation is an effective analgesic technique that potentiates the analgesic effect of oral sugar. It can be used for minor painful procedures on newborns.     

Variability in pain response to a non-pharmacological intervention across repeated routine pain exposure in preterm infants: a feasibility study

Aim: To explore the variability in pain response in preterm infants across time who received sucrose during routine heel stick.
Method: Single group, exploratory repeated measures design.
Setting: Two tertiary level neonatal intensive care units (NICU) in Switzerland.
Subjects: Nine preterm infants born between 28 2/7 and 31 4/7 weeks of gestation during their first 14 days of life.
Measurements: Pain was assessed by the Bernese Pain Scale for Neonates (BPSN), the Premature Infant Pain Profile (PIPP) and the Visual Analogue Scale (VAS). Salivary cortisol was analysed.
Results: 72–94% of the variability was within-subject variability, indicating inconsistency of pain responses across the 5 heel sticks. Interrater agreement was highest during heel sticks 1–3 and decreased during heel stick 4 and 5, indicating a possible alteration of pain patterns. No significant differences in the amount of cortisol could be detected before and after the heel sticks (p = 0.55), indicating no stress-induced peak after the painful intervention. However, a general gradual decrease of cortisol levels across time could be detected.
Conclusion: A high variability in pain response among preterm neonates across time could be described. Consistency of cortisol levels before and after the heel sticks could indicate the effectiveness of sucrose across time.
