This guide outlines essential admission procedures for labor, emphasizing the importance of early reporting and accurate diagnosis, especially for high-risk pregnancies. The document describes how to distinguish between false and true labor, highlighting clinical signs such as contraction regularity, cervical dilation, and accompanying discomfort. It also covers vital monitoring, maternal comfort, and strategies for managing both stages of labor, including pain relief, fluid administration, and fetal monitoring techniques. Early recognition and proper management can enhance maternal and fetal outcomes during childbirth.

Admission procedures Dr. F Mostajeran MD
Admission procedures • Urged to report early in labor • Early admittance to labar , delivery unit • especially high risk pregnancy • accurat diagnosis of labar • Falsely diagnosed , inappropriate in terrention • Not diagnosed (remot from medical personnel medical facilities)
Definition of labor • Uterine contractions that bring effacement and dilatation of cervix. • Painful contractions become regular • onset of labor as beginning at the time of admission to the labor unit • Admission for labor based on dilatations accompanied by painful contractions .
D. Diagnasis between false and true labor is difficult • Contractions of true labor • Regular intervals • Intervals gradually shorten • Intensity gradually increases • Discomfort back , abdomen • Cervix dilates • Discomfort is not stopped by sedation
Contractions of false labor • Irregular intervals • Intervals long • Intensity unchanged • Discomfort lawer abdomen • Cervix not dilate • Relieved by sedation
Pregnant woman who is having Cantractions • Emergency condition • Labor is defined as process of childbirth beginning • Latent phase delivery placenta
Electronic admission testing • Recommend NST or CST on all patient • (labar – delivery unit) • Fetal admission test • identify unsuspected cases
Vaginal examination • Amnionic fluid effacement • Cervix dilatation position • Presenting part • Station • Pelvic architecture
Detection of ruptured membranes • Leakage of fluid • Prolapse cord • Labor occur • Serious intra uterine infection • Nitrazine paper (PH= 7.0 – 7.5) • Arborization or ferning • Alpha – fetoprotein • Injection various dyes
Vital signs and review of pregnancy record • Physical examination • Preparation of vulva and perineum • Inspection and cleaning of the vulva , perineum , mini – shave - enema
Friedman • Three functional divisions of labor • Preparatory division: Little cervical dilatation Considerable change • Dilatational division : Most rapid rate • pelvic division: Deceleration phase of cervix - dilatation Cardinal fetal movements
Cervical dilatation • Latent phase (14-20h) • Active phase: acceleration ,phase of maximum slope , deceleration phase
Management first stage of labor • Remainder of general physical exam is completed • HCT HB protein - glocose • average duration first stage of labor • 7 hours in nulliparous w • 4 hours in parous w
Fetal monitoring during labar • Contractions and response FH • Suitable stethoscopc , doppler ultrasonic devices • FH should be checked after contractions • every 30 minutes (15) • Second stage every 15 minutes (5) • Cantinous electronic monitoring
MATERNAL MONITORING • Vital signs • T , pulse , BP every 4/h • PROM temprature every 1/h • 18 h of PROM antimicrobial
Subsequent vaginal examinations • When membrans rupture if head was not Defenetly engaged • fetal H immediately and during the next uterine contraction • (occult umbilical cord compression) • periodic examinations at 2-3 hours interval
Oral intake • Gastric emptying time prolanged (food – medication remain in the stomach – not absorbed may be vomited) • Food should be withheld • Intravenous fluids • Infusion system routine early labar (IV line) • Longer labors glucose sodium water 60-120 ml/hr
Maternal position during labor • normal laboring woman • Not be confined to bed • Comfortable chair • In bed position most comfortabl (lateral recumbend)
Analgesia • Is initiated on the basis of maternal discomfort • vaginal examination befor administration of analgesia (delivering a depressed infant) • Timing , method and size of initial and subsequent dose , interval of time until delivery
Amniotomy • There is a great temptation • Benefits: rapid labor detection of meconium staining • Internal fetal M • Aseptic technique • Head must be well applied to the cerxin
Urinary bladder function • Bladder distention avoid • Abstracted labor • Subsequent bladdes hypotonia, infection • Suprapubic region shauld be visualized , palpated detect filling bladder • If could not void on a bedpan • Intermittent catheterization
Management of second stage labor • Full dilatation of the cervix • Begins to bear dawn • 50 minutos in nulliparous • 20 minutos in multiparous
Higher parity 2-3 expulsive efforts may suffice Complete the delivery of the infant • FHR • Low – risk 15 H.risk 5
Fetal H.R • Contraction – maternal expulsive efforts • FHR are not consequence of head compression • Descent fetus and reduction in uterine volume • some degree of premature separation placenta
tighten a loop or loops of umbilical cord • Around the fetus umbilical blood flow • Prolonged uninterrupted maternal expulsive efforts dangerous to the fetus
Preparation for delivery • Variety of positions • Dorsal lithotomy position • For beter exposure legholders stirrups • Cramps in the legs (brief massage – changing position) • Preparation for delivery entails vulvar and perineal cleansing
Spontaneous delivery • Delivery of the head • Contraction perineum bulges • Vulvovaginal opening becomes more dilated • Gradually circular opening • This encirclement of the largest head • By the vulvar ring is known as crowning
Perineum is extremely thin • Episiotomy , laceration • Episiotomy risk tear external anal – rectum • Episiotomy - anterior tear urethra , labia
Ritgen manover • Vaginal introitus 5 cm • Towel – draped , gloved hand forward pressure • on the chin of the fetus • other hand exerts pressure superiorly against occiput
Cleaning the nasopharynx • Minimize aspiration AF – debris , blood • once thorax is delivered • face quickly wiped nause , mouth are aspirated
Following delivery of anterior shoulder • Finger should be passed to the neck • Nuchal cords 25% + • Drawn down , loose – slipped over the head • Clamping the cord • 4-5 cm , 2-3 cm fetal abdomen two clamps • Plastic cord clamp
Timing of cord clamping • Infant is placed at or below vaginal interoitus 3 , 80ml of blood shifted from placenta to infant • 80ml 50mg Iron , Iron deficiency anemia • Maternal alloimmunization • our policy after cleaning airway 30" cord clamp
Management of the third stage • After delivery of the infant • Height uterine fundus • Uterus firm , no unusual bleeding • Waiting until placentac separat – no massage • Hand rest on the fundus (atonic – filled with blood)
Signs of placental separation • uterus becames globular firm • Sudden gush of blood • Uterus rises (placenta separated , passes dawn to lower u-segment • Its balk pushes uterus upward • Umbilical cord protrudes forther out
delivery of the placenta • Traction on the umbilical cord must not be used inversion • Manaol removal of placenta • occasionally placenta will not separat • At any time brisk bleeding and , placenta can not be delivered • Active management of the third stage • 5 units oxytocin +0.5 ergometrine • reductian in the length of third stage
Fourth stage of labor • Exam placenta , membranes , umbilical cord • Completeness , anomalies • Hour immediately fallowing delivery • Critical fourth stage of labor • uterine atony , BP , pulse every 15
Oxytocic Agents • Oxytocin (pitocin , syntocinon) • Methylergo novine maleat (methergine) • Reduce blood loss by stimuloting myometrial contraction • Iml 10IU half – lifc IV 3 • Inapropriate dose kill the fetus ,rupture uterus
Cardiovascular effects • Deleterious effects follow IV bolus • Antidiuresis • rare maternal convulsion antidiuretic action • Water intoxication (20,40mu/minut ) • Concentration should be increared rather than rate of flow • Normal saline are lactated ringer solution
