The Effects Of Cold Two Different Compress Modes On Swelling And Pain Among Patients Receiving Extraction Of Impacted Tooth Of Mandibular

ObjectiveTo examine the effects of two different cold compress modes(continuous cold compress and intermittent cold compress)on the pain and swelling among patients receiving extraction of impacted tooth of mandibular.MethodA randomized controlled trial was conducted.Participants were recruited from January 2016 to August 2016 in Affiliated Stomatology Hospital of Fujian Medical University,China.64 of participants were randomly assigned to the experimental and the control group.The participants in the experimental group received the usual care plus continuous cold compress.The participants in the control group received the usual care plus intermittent cold compress.The continuous cold compress means that patients were given the 10% salt water ice packs on the side mandibular angle immediately after the tooth extraction and the treatment was continued for 24 hours.The intermittent cold compress means that each cold compress lasted for 30 minutes,then took a rest for 1 hour,and circulate the above method for 24 hours.Outcomes included pain,and skin temperature were measured at baseline and per hour after the intervention and the swelling was measured at baseline,1hour,6 hours,12 hours,18 hours,and 24 hours after the intervention.ResultsShown by the results of analysis of repeated measurement of variance,the pain of the experimental group was lower than the control group((F=116.107,P<0.001).The pain of the experimental group was affected by time factor(F=22.151,P<0.001),had relieved significantly with the observation point migrating.The swelling of the experimental group was lower than the control group((F=116.107,P<0.001).The swelling of the experimental group was affected by time factor(F=31.228,P<0.001),had reduced significantly with the observation point migrating.The skin temperature of the experimental group was lower than the control group(F=7124.704,P<0.001).The skin temperature of the experimental group was affected by time factor(F=1194.412,P<0.001),had reduced significantly with the observation point migrating.ConclusionsThis study showed that the continuous cold compress was more effective in reducing the pain and swelling among the patients receiving extraction of impacted tooth of mandibular.There was no adverse reaction during the course of continuous cold compress.Compared with the intermittent cold compress,it suggested that continuous cold compress can be integrated into usual care to reduce the pain and swelling among the patients receiving extraction of impacted tooth of mandibular.
