Infantile colic is a common problem, affecting 10-20% of newborns. Both the baby and the parents are suffering and there is a risk that the early relationship is disturbed. There is no safe and effective drug and the use of complementary medicine is increasing in spite of weak or no evidence. Acupuncture releases different neurotransmitters and hormones, is calming, gives pain reduction and affects digestion. Therefore it is reasonable that acupuncture can have effect in colic. Acupuncture in infantile colic has shown promising results in the few scientific trials conducted. These trials have evaluated the effect of standardized minimal acupuncture in the acupuncture points Large Intestine 4 (LI4) (two trials) or Stomach 36 (ST36) (one recent trial). In this prospective randomized three armed, multi center study performed at Child Health Centers in three towns, the effect of acupuncture in reducing symptoms in infants, 2-8 weeks old, with colic will be investigated. Two types of acupuncture: standardized minimal acupuncture in LI4 and individualized acupuncture in different points according to symptoms will be compared to an untreated group. Parents (who register the infants crying) and the nurse they meet at the study CHC are blinded.

Parents will get information about the trial from nurses and doctors at Child Health Centers (CHC) or from a web-site (www.spädbarnskolik.se). Parents who are interested in letting their infant participate in the trial get further information and sign informed consent. The trial is approved by the ethical board at Lund University.

Infant´s crying, fussing, sleep, feeding and stooling will be registered in a diary during a baseline week. Infants who cry/fuss more than three hours/day, more than three days during this week is included and randomized. Beside their ordinary contacts with their Child Health Center (CHC), infants and their parents are invited to visit a study CHC twice a week for two weeks, where they meet a nurse for about 20 minutes. Parents can describe their situation, discuss the infant´s symptoms and get advice. This nurse is blinded to which group the infant is randomized to. She carries the baby to another room and hands over the infant to a nurse, trained in acupuncture. The acupuncture nurse randomizes the infants to one of three groups, following a randomization list produced by the research department at Lund University Hospital. Group A will get standardized minimal acupuncture: one needle is inserted about 3 mm in the point LI4 on the infants hands, unilaterally, for 2-10 seconds and then withdrawn. Group B will get individualized acupuncture in points chosen by the acupuncturists according to symptoms: maximum 5 needles are inserted about 3 mm in points recommended in a guideline produced for the trial after discussions with experienced pediatric acupuncturists. Needles are retained for maximum one minute. Group C will not get acupuncture but will otherwise be treated similarly: they will be with the acupuncture nurse for five minutes while she holds the hand of the baby and talks to it in a calm voice. The acupuncture nurse make notes about bleeding and other possible side effects, and if the baby is crying. After approximately five minutes the acupuncture nurse calls the study nurse who carries the baby back to the parents. At every visit the study nurse asks parents if they have noticed any side effects, and asks if parents believe their baby gets acupuncture or not.

During the two intervention weeks and one week after the last visit to the study CHC parents register the infants behavior daily in a diary. Statistical analyses will be made from the diaries.
