Ultrasound and Prolonged Labour
This observational study is designed to correlate findings on ultrasound with manual palpation, and to consider if delivery outcome can be predicted with help of ultrasound. Specifically, the study will evaluate the significance of fetal head level (descent) in the pelvis, measured with ultrasound.
To correlate findings on ultrasound with manual palpation, and to consider if delivery outcome can be predicted with help of ultrasound. Specifically evaluate the significance of fetal head level (descent) in the pelvis, measured with ultrasound.
Labours have traditionally been evaluated by manuals methods of the "delivery helper" - midwives or doctor. There are many factors that will prolong labour such as malcontractions, disproportion of the birth canal and malpresentation/position. In about 20% of primigravidae, the first stage will last longer than 10 hours.
In this study we want to evaluate different ultrasounds measurements to see if ultrasound can be used to predict the outcome of labour.
A descriptive observational study, with one ultrasound examination. The labour will be handled according to definitions by Woman's department, Stavanger University Hospital, and WHO.
The use of stimulating agents, as Oxytocin, will be evaluated after manual examinations, specific definitions and criteria.
The results of the ultrasound examinations will be evaluated after the delivery, since the results are not to be used clinically during the delivery.
Inclusion criteria will be primigravidae, with one fetus, after the 37th week. Feta head presentation. Ruptured membranes, at least one hour before inclusion. Prolonged first stage according to WHO definitions. The target is to include 100 subjects.
Inter- and intraobserver variation will be evaluated with intraclass coefficients. We will analyze operative delivery with normal vaginal delivery. Also, two groups divided by the stage 0 will be evaluated with statistics analyzes.
Time to delivery will be evaluated with Kaplan Meier and Cox regression analyzes.

Ultrasound scanning of the back has been shown to increase success when used to guide epidural catheter insertion. However, this technique is not applied widely in clinical practice. Str...
Accidental dural puncture is a potential complication of epidural analgesia for labour and delivery. When it happens, it may cause debilitating headaches and other symptoms that prevent mo...
To determine, among healthy first time mothers who are uncertain as to when to come to hospital in labour, if home visits by obstetrical nurses compared to telephone advice have an impact ...
We designed a two arms prospective, randomised, simple blinded trial to compare the impact of clear liquid intake on gastric content before delivery. We hypothesize that there will be ...

It has been suggested that low serum zinc levels may be associated with suboptimal outcomes of pregnancy such as prolonged labour, atonic postpartum haemorrhage, pregnancy-induced hypertension, preter...
OBJECTIVE. Ultrasound of the thigh presents unique challenges because of the size and length of multiple structures, including tendons, muscles, nerves, and vessels. Those performing ultrasound can us...
Ultrasound imaging of the spine is thought to reduce failed and traumatic neuraxial procedures. Most of the evidence supporting this assumption has been produced in the context of an expert sonographe...
Introduction. Recent evidence indicates that clinical examination, for determination of fetal head position, is subjective and inaccurate. Present study was aimed to compare transabdominal ultrasound ...

Medical and Biotech [MESH] Definitions
The inspection of one's own body, usually for signs of disease (e.g., BREAST SELF-EXAMINATION, testicular self-examination).
The use of ultrasound to guide minimally invasive surgical procedures such as needle ASPIRATION BIOPSY; DRAINAGE; etc. Its widest application is intravascular ultrasound imaging but it is useful also in urology and intra-abdominal conditions.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
A raised flat surface on which a patient is placed during a PHYSICAL EXAMINATION.
Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.
