RESUMO
Objective:To evaluate the effectiveness of hands-on training and video demonstration in training of forceps delivery for residents.Methods:Forty nine residents who were rotating in the obstetrics department of Peking Union Medical College Hospital from 2019 to 2021 were enrolled. The residents were randomly divided into two groups: the instructor group ( n=24) was taught by hands-on training of forceps delivery and the video group ( n=25) was instructed by watching video demonstration. All the trainees completed the self-confidence questionnaire survey, and were evaluated by written tests and objective structured assessment of technical skills scoring system. Results:The scores of self-confidence in each item after the simulation training were higher than those before training in both groups; and there were no significant differences between two groups in the increment of scores(mastering knowledge: 1.54±0.98 vs. 1.40±0.71, U=266.68, P=0.480;mastering operation skills: 1.42±0.93 vs.1.80±0.87, U=233.47, P=0.161; mastering forceps structure: 1.63±1.10 vs. 1.88±0.93, U=261.63, P=0.416; confidence in independent operation: 1.13±0.90 vs. 1.00±1.08, U=287.74, P=0.799; evaluation of simulation training: 0.21±0.51 vs. 0.16±0.55, U=288.27, P=0.776). In the written tests, the scores of the instructor group were significantly higher than those of the video group (83.00±7.18 vs.70.56±10.37; t=4.86, P<0.001). In the practical operation, the instructor group significantly outperformed the video group in items of “right blade placement” (0.71±0.46 vs. 0.20±0.41, U=147.54, P<0.001), “objective total score” (6.17±1.46 vs. 4.72±1.65, U=155.49, P=0.003) and “correct traction” (0.85±0.31 vs. 0.56±0.51, U=213.86, P=0.036). Conclusion:Training delivered via hands-on instruction and demonstration was generally more effective than that delivered via video, although both groups show a increased self-confidence in learning and performing forceps delivery.
RESUMO
In this study, 15 second-year resident doctors who had standardized training of OBGYN were taken as research subjects to discuss the effect of training resident doctors with obstetrics forceps by using simulation teaching method. The simulation teaching process includes theoretical study, theoretical examination, simulation teaching of forceps skills and Assessment of forceps skills. In theoretical study section: before learning to use forceps, the students acquired the theoretical knowledge by flipped teaching micro-video mode. In theoretical examination section: the mastery of basic clinical knowledge of using forceps was evaluated through online assessment. In simulation teaching of forceps skills: students who scored 8/10 points were admitted to enter the simulation teaching process, and they had practical training of scenario simulation skills in Clinical Skills Center. In assessment of forceps skills: the mastery of forceps skills was evaluated by standardized forceps delivery procedure items. The results showed that the students in the simulation teaching group had excellent teaching assessment results, and the resident doctors had more confidence in operating forceps independently, and the teaching effect was ideal, which could further promote the simulation teaching of obstetric clinical skills.
RESUMO
OBJECTIVE: To investigate the reasons and prevention and treatment measures of acute third-and fourthdegree obstetric lacerations.METHODS: A retrospective analysis of 83 cases of acute third-and fourth-degree obstetric lacerations in the First Affiliated Hospital of Kunming Medical University from 2010 to 2016 was performed.RESULTS:(1)The incidence of 3 rd or 4 th degree laceration was 0.394%(83/21 083),which was 0.433%(72/16 620)in primiparas and 0.246%(11/4463)in multiparous women,there being a statistical difference(P<0.05).(2)The incidence of 3 rd or 4 th degree laceration was significantly increased in the group with episiotomy than without episiotomy[0.583%(48/8229)vs.0.272%(35/12 854),P<0.05].(3)The incidence of 3 rd or 4 th degree laceration was significantly increased in the group with Forceps delivery than without Forceps deliery[3.120%(37/1186)vs.0.231%(46/19 897),P<0.05].(4)In patients with forceps delivery,the incidence of 3 rd or 4 th degree laceration was 2.911%(28/962)in episiotomy group and 4.018%(9/224)in without episiotomy group,there being a significant difference(P<0.05).(5)The incidence of 3 rd or 4 th degree laceration was significantly increased in the macrosomia group than in the non-macrosomia group[1.225%(11/898)vs.0.357%(72/20 185),P<0.05].(6)The incidence of 3 rd or 4 th degree laceration was significantly increased in the prolonged second stage group than in the normal second stage group[2.381%(24/1008)vs.0.294%(59/20 075),P<0.05].CONCLUSION: The incidence of third-and fourth-degree obstetric lacerations is increased in primiparous women,episiotomy,forceps delivery,forceps delivery without episiotomy,big fetal weight and prolonged second stage.
RESUMO
Objective To investigate influential factors and incidence of postpartum urinary retention after forceps delivery. Method The clinical data of 216 cases of puerperas undergoing forceps delivery in our hospital from January 2012 and July 2015 were collected and investigated in terms of postpartum urinary retention as well as its influencing factors. Results The incidence rate of postpartum urinary retention was 24.07%(52/216).Logistic multivariate regression analysis showed the significant positive variables for the outcomes included:the first stage of labor and postpartum 2h bleeding.Conclusion The first stage of labor time and postpartum 2h bleeding are the high risk factors of uroschesis after forceps delivery.
RESUMO
Objective To investigate the influence of forceps delivery or emergency cesarean section on the maternal and infant outcome in pregnant women with abnormal second stage of labor.Methods We retrospectively analyzed the clinical data of 118 parturients with abnormal second stage of labor in the department of obstetrics and gynecology in our hospital from 2013 January to 2015 February.The involved parturients with abnormal second stage of labor received different delivery modes including forceps delivery and emergency cesarean section, and the delivery time and its influence on the maternal and infant outcome were compared.Results The mean delivery time of forceps delivery and emergency cesarean section was (14.8 ± 5.3) and (32.7 ± 12.6) minutes, the difference was significant (P＜0.05).The bleeding probability and the occurrence of severe neonatal asphyxia in the forceps delivery group was obviously lower than that of maternal emergency cesarean section group (P＜0.05).The influence of emergency cesarean section on the newborn severe asphyxia was more serious than forceps delivery (P ＜0.05).There was no statistical difference in the mild asphyxia, facial bruising, scalp hematoma and neonatal pneumonia between the two groups.Conclusion Compared with emergency cesarean section, forceps delivery can protect the safety of mother and child can reduce dystocia risk coefficient for the pregnant women with abnormal second stage of labor.
RESUMO
Ankylosis of the temporomandibular joint following forceps delivery is a rare anomaly. The aetiopathogenesis involves wrongful application of the forceps or forceful closure of the forceps handle against the condyle with haemathrosis, organisation and subsequent ankylosis. Because of the lack of epidemiological data, there is little information about the true incidence and the management of this rare anomaly. The purpose ofthis presentation is to report the challenges encountered in the airway management of a six-year old female with right temporomandibular joint ankylosis following forceps delivery in a private hospital setting.
La anquilosis de la articulacion temporomandibular tras el uso de forceps siguientes es una rara anomalia. La etiopatogenesis implica la aplicacion indebida de los forceps o el cierre forzoso del mango de los forceps contra el condilo con hemartrosis, organizacion y subsiguiente anquilosis. Debido a lafalta de datos epidemiologicos, hay poca informacion acerca de la verdadera incidencia y el tratamiento de esta rara anomalia. El objetivo de esta presentacion es informar los problemas encontrados en el tratamiento de las vias respiratorias de una niha de seis ahos con anquilosis de la articulacion temporomandibular derecha tras de un parto con forceps en el contexto de un hospital privado.
