Primary Outcomes

Description: At 3 times (pre-mydriasis, 1 hour and 3 hours after Cyclomydril drops), subjects were exposed to ambient lighting for a period of five minutes. This usually entailed removing isolette covers and exposing the patient to the ambient room light. During this time, pain and vital signs were recorded every minute. Heart rate was recorded directly from their cardio-respiratory monitor (Agilent M1106C). The mean of the five recorded values for each variable was used

Secondary Outcomes

Description: At 3 times (pre-mydriasis, 1 hour and 3 hours after Cyclomydril drops), subjects were exposed to ambient lighting for a period of five minutes. This usually entailed removing isolette covers and exposing the patient to the ambient room light. During this time, pain and vital signs were recorded every minute. Respiratory rate was recorded directly from their cardio-respiratory monitor (Agilent M1106C). The mean of the five recorded values for each variable was used

Description: At 3 times (pre-mydriasis, 1 hour and 3 hours after Cyclomydril drops), subjects were exposed to ambient lighting for a period of five minutes. This usually entailed removing isolette covers and exposing the patient to the ambient room light. During this time, pain and vital signs were recorded every minute. Pain scores were recorded by direct observation using the Neonatal and Infant Pain Scale (NIPS). The mean of the five recorded values for each variable was used. NIPS scoring consists of 6 measures associated with neonatal or infant pain, each with a range of 0-7 with low scores (0-2) associated with no pain and scores > to 4 associated with severe pain. Maximum scoring would be 42 for severe pain and minimal being 0 for no pain. The six measures on NIPS include: facial expression, crying, breathing patterns, arm movements, leg movements and state of arousal.
