Syringe preparation technique and minor adverse reactions to diphtheria-tetanus-pertussis immunization. 1987

Minor local reactions and subcutaneous abscesses following diphtheria, tetanus and pertussis immunization have been attributed to vaccine left in the subcutaneous needle path from vaccine coating the needle. Various syringe preparation techniques have therefore been advocated to prevent reactions. To evaluate these recommendations we compared rates of minor reactions in 200 children randomly assigned to one of three groups that differed only in the handling of the filled syringe: in Group 1 the needle was changed before injection; in Group 2 the needle was wiped with sterile gauze before injection; in Group 3 the same needle was used to draw up and to inject the dose and was not wiped. Overall 27% of children had febrile (greater than 38 degrees C) reactions, 62% became fussy and 79% had a local reaction. Rates of reactions were nearly identical in the three groups, except that children in group 2 receiving their second dose or more of diphtheria-tetanus toxoid-pertussis vaccine were more likely to become febrile at greater than 38 degrees C (32%) or fussy (78%) (P less than 0.05 and P less than 0.02, respectively). We conclude that changing needles does not reduce the rate of minor local and systemic reactions. Wiping needles may increase the rate of reactions.

D007273	Injections, Intramuscular	Forceful administration into a muscle of liquid medication, nutrient, or other fluid through a hollow needle piercing the muscle and any tissue covering it.	Intramuscular Injections,Injection, Intramuscular,Intramuscular Injection
D009339	Needles	Sharp instruments used for puncturing or suturing.	Hypodermic Needles,Hypodermic Needle,Needle,Needle, Hypodermic,Needles, Hypodermic
D010567	Pertussis Vaccine	A suspension of killed Bordetella pertussis organisms, used for immunization against pertussis (WHOOPING COUGH). It is generally used in a mixture with diphtheria and tetanus toxoids (DTP). There is an acellular pertussis vaccine prepared from the purified antigenic components of Bordetella pertussis, which causes fewer adverse reactions than whole-cell vaccine and, like the whole-cell vaccine, is generally used in a mixture with diphtheria and tetanus toxoids.

D011897	Random Allocation	A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.	Randomization,Allocation, Random

D002986	Clinical Trials as Topic	Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.	Clinical Trial as Topic
D004168	Diphtheria Toxoid	The formaldehyde-inactivated toxin of Corynebacterium diphtheriae. It is generally used in mixtures with TETANUS TOXOID and PERTUSSIS VACCINE; (DTP); or with tetanus toxoid alone (DT for pediatric use and Td, which contains 5- to 10-fold less diphtheria toxoid, for other use). Diphtheria toxoid is used for the prevention of diphtheria; DIPHTHERIA ANTITOXIN is for treatment.	Diphtheria Vaccine,Toxoid, Diphtheria,Vaccine, Diphtheria
