Cord blood acid-base status in neonates delivered by Silastic vacuum cup extraction: comparison with forceps and spontaneous deliveries.

Umbilical cord blood gases were measured as objective parameters of neonatal outcome in patients delivered by Silastic vacuum extractor and were compared with those values from patients delivered spontaneously, by forceps, or by sequential use of vacuum and forceps. The results demonstrated no clinically significant differences among the groups in cord blood pH, pCO2, pO2, base excess, or bicarbonate values. These observations provide reassurance that the Silastic vacuum extractor is a safe alternative for vaginal delivery of the appropriately selected term fetus.

[More on the Kielland forceps].

A study of 103 deliveries with Kielland forceps has been presented. Mother's age, parity, presentation, height of the head, anaesthesia, weight of the child, failures, puerperium, indications, injuries to the mother, conditions of the child, maternal and children mortality are discussed. Kielland instrument still maintains its position as a usefull specialized forceps for deep transverse arrest and also for obliqually placed fetal head.

Outcome of forceps delivery versus vacuum extraction--a review of 200 cases.

The outcome of 100 patients undergoing instrumental delivery with vacuum extractor is compared with that of 100 women delivered with the aid of obstetric forceps. Forceps deliveries were more commonly associated with maternal birth canal trauma (including episiotomy) whilst vacuum extractor carried higher odds of the neonate developing jaundice. Apart from these, there were no significant differences between these two groups in terms of maternal morbidity, neonatal trauma and morbidity and ultimate outcome (success with the type of instrument used). We conclude that with meticulous handling of the instrument and with an appropriate decision on the indication and the type of instrument used, the maternal and neonatal outcome could be equally good with the use of either instrument.

[Mechanical action of obstetrical forceps on the fetal skull].

By means of schematic illustrations we demonstrate the working point of the power of labour, obstetrical forceps and vacuum extractor, The bones of the fetal skull are by sutures movable fastened together. Every extraction so will rise the intracranial pressure of the fetus, because the resistance of the birth canal tissues must be overcome. This for the extraction needed power and rising of the intracranial pressure is independent from the instrument with which the extraction is carried out. It is impossible to make a "cage" around the fetal head with the Shute forceps during extraction, to protect the fetal head from the extraction power. Another question is, that some instruments (included vacuum extractor) can limit the used power. By using forcipes with crossed lock without fixation the forces for extraction are not limited and there is a need of better operative technic. By the comparison of the forcipes from Shute, Naegele and Zweifel we can summarize, that for success is decided the indication and good operative technic and not the instrument. Every instrument for vaginal extraction has advantages and disadvantages in different obstetrical situations.

Forceps delivery at Wesley Guild Hospital, Ilesa, Nigeria: a ten year review.

In a ten year review in a Nigerian teaching hospital, forceps delivery accounted for 2.1% of the total births. Delivery was at 36-40 weeks in majority (79.3%) of the patients and primiparae accounted for 45.4% of the cases. The procedures were performed as emergencies in 78.6%, while the majority (91.1%) were outlet forceps deliveries. The common indications were prolonged second stage of labour (58.7%), hypertension in pregnancy/pre-eclampsia (10.3%), fetal distress (9.2%), eclampsia (8.1%) and maternal distress (5.9%). Bruises of the fetal head and fracture of the skull complicated 9.2% and 2.2% of the cases respectively. The main maternal complications were post-partum haemorrhage (3.3%), puerperal sepsis (2.9%), broken down episiotomy repair (2.9%), third degree perineal tear (2.2%) and vaginal lacerations (2.2%). Measures aimed at reducing the associated hazards are suggested.

[Forceps delivery--obstetric indications and outcome].

Authors analysed 170 forceps delivery in comparison to the control group of normal vaginal delivery. We analysed mothers age, obstetrical history, gestational age and duration of labour as well as traumatization, loss of blood and hospitalisation time. Analysed concerned as well the newborns state in the Apgar score its delivery way and newborn injuries. The most frequent indication for the forceps delivery was the imminent foetal asphyxia. The second stage of delivery lasted significantly longer, the blood lost was greater and the hospitalisation prolonged. Newborns presented poorer after-delivery condition measured in the Apgar score.

New system of intraocular instruments. I. Guillotine intraocular forceps.

A four-instrument system of 20-gauge, rustproof intraocular forceps can be used in conjunction with pars plana vitrectomy to (1) extract intraocular foreign bodies, (2) manipulate intraocular tissue and a dislocated pseudophakos, and (3) obtain biopsy specimens of vitreous gel and abnormal preretinal and epiretinal membranes. The forceps can also be used as an intraocular needleholder for transvitreal suturing of selected giant retinal tear flaps. These instruments are lightweight and sturdy and use a guillotine action and a new barrel-handle design. To facilitate introduction and use through a pars plana approach, the various jaw faces are angled 135 degrees from the long axis. Prototype models have been used successfully in numerous and varied clinical applications.

Autosomal recessive inheritance in the Setleis bitemporal 'forceps marks' syndrome.

We present the clinical findings in two children with the Setleis bitemporal "forceps marks" syndrome. The striking features include the following: (1) bitemporal scarring, an anomaly that resembles forceps marks; (2) periorbital puffiness with wrinkling of the skin; (3) abnormalities of the eyebrows; (4) anomalies of the eyelashes; (5) flattening of the nasal bridge with a bulbous nasal tip; (6) increased mobility of the skin, associated with severely redundant facial soft tissue; and (7) normal growth and development. The evidence that suggests that this unusual syndrome is inherited in an autosomal recessive fashion includes the following: (1) seven of the patients have come from the relatively isolated towns of San Sebastian and Aguadilla in Puerto Rico; (2) two sets of affected siblings have been described, and, in both cases, the siblings' parents were normal; and (3) one of the children described herein is the product of a consanguineous mating. Although the pathogenetic mechanism is unknown, Setleis syndrome is clearly inherited as an autosomal recessive trait.

Retrieval of dislodged and disfigured transradially delivered coronary stent: report on a case using forcep and antegrade brachial sheath insertion.

We report a case of dislodged and damaged stent during transradial coronary procedure using 6 Fr device, which was successfully retrieved by using a forcep and 8 Fr antegrade brachial sheath. The disfigured and bulky stent can be removed, after their retrieval from the coronary circulation, using a forcep inserted through an 8 Fr brachial artery sheath if the radial artery is deemed too small to accommodate larger sheath.

Percutaneous tracheostomy with the guide wire dilating forceps technique: presentation of 171 consecutive patients.

BACKGROUND: Evaluation of percutaneous tracheostomy (PT) with the guide wire dilating forceps (GWDF) technique. METHODS: Prospective study of perioperative complications, retrospective analysis of early and late complications in an ICU in a teaching university hospital. RESULTS: The success rate of the procedure was 96.5%. The average procedure time in 171 consecutive patients was 5.0 min. Perioperative complications requiring surgical or medical intervention occurred in 6.4% of 171 patients. This included conversion to surgical tracheostomy, which was necessary in six patients (3.5%). Major complications while being cannulated occurred in 2.4% of 164 patients but seemed mostly unrelated with the GWDF technique itself. Late complications (after decannulation) were mostly minor and occurred in 22.6% of 106 patients. Only one patient (0.9%) had a symptomatic tracheal stenosis developed. CONCLUSION: Percutaneous tracheostomy with the guide wire dilating forceps technique is easy to perform at the bedside with few late complications. However, in our study, perioperative and immediate postoperative bleeding complications (minor and major) occur quite often.

Transfemoral liver biopsy by forceps: a review of 104 consecutive procedures.

PURPOSE: Transvenous liver biopsy is performed on patients with contraindications to percutaneous biopsy. Transfemoral liver biopsy has not been widely reported, and we present our experience of 104 consecutive procedures. METHODS: During a 30-month period, 88 patients underwent 104 transfemoral liver biopsies. Under fluoroscopic guidance a 9 Fr curved introducer catheter is passed into the right hepatic vein via a standard femoral sheath. A 7 Fr biopsy forceps is then passed into the liver, opened and wedged. Prior to biopsy, the image intensifer is rotated so the relation of the capsular surface to the biopsy site is verified and capsular perforation avoided. RESULTS: Tissue samples obtained in 97 of 104 procedures (93%) were adequate for diagnosis in 83 (80%). Complications occurred in six procedures (6%) including two capsular perforations; the latter two were treated by coil embolization. CONCLUSION: We found transfemoral liver biopsy using forceps to be a safe, well-tolerated procedure with a high diagnostic yield and it is a technically easy alternative to the transjugular approach using large needles.

Transcatheter coil closure of large patent ductus arteriosus with 0.052-inch Gianturco coils using myocardial biopsy forceps in a 70-year-old woman.

Small patent ductus arteriosus is generally closed in children using a transcatheter coil. This is done less often in older patients or those with large patent ductus arteriosus. We report successful antegrade transcatheter coil closure of patent ductus arteriosus in a 70-year-old woman. Into the patent ductus arteriosus, using flexible myocardial biopsy forceps, we placed two large 0.052-inch Gianturco coils, which were easily used as multipurpose vascular occlusion coils. The forceps and the coils were readily available and provided complete occlusion. Other delivery devices cannot deliver such large coils. Transcatheter coil closure thus appears to be safe and effective for closing large patent ductus arteriosus in the elderly.

Chorionic villus sampling by rigid forceps: experience with 300 cases at risk for thalassemia major.

In this article we report the results of chorionic villus sampling by a biopsy forceps inserted via the cervix under ultrasonic guidance in 300 pregnancies at risk for thalassemia major. A sufficient amount of chorionic villi for deoxyribonucleic acid analysis by oligonucleotide hybridization was obtained in all cases tested but one, with a success rate of 99.7%. The percentage of fetal loss, expressed as proportion of continuing pregnancies, was 4.8%. To verify the results, we carried out amniocyte deoxyribonucleic acid analysis in all the continuing pregnancies for the first 100 cases and in those in which trophoblast deoxyribonucleic acid analysis showed the heterozygous state for beta-thalassemia for the second 200 cases. At the beginning we had two cases of decidual contamination in such an amount to cause misdiagnosis. Successively more careful elimination of decidual tissue from villi avoided avoided this pitfall. These results indicate that chorionic villus sampling by a rigid forceps is a reliable and relatively safe method for fetal diagnosis of genetic diseases by deoxyribonucleic acid analysis.

Routine cleaning and the elimination of Campylobacter pylori from endoscopic biopsy forceps.

The effect of routine cleaning in removing Campylobacter pylori from the biopsy forceps of endoscopes has been examined in a series of 50 patients. Campylobacter pylori was isolated from the biopsies of 15 of the patients, while one of the 50 biopsy forceps washings yielded the organism after routine cleaning. This study suggests that there is a small chance of transmitting C. pylori by endoscopic equipment if cleaning is the only method of decontamination adopted.

Intraoperative breakage of 20-gauge Tano forceps.

PURPOSE: To report three cases with breakage of a 20-gauge kryptonite forceps during vitreoretinal surgery. DESIGN: Interventional case report. METHODS: Pars plana vitrectomy that included a membrane peeling was performed in three patients through standard ports with 20-gauge vitrectomy systems. The peeling procedure was attempted with the end-gripping kryptonite forceps. RESULTS: Intraoperatively, the branch/tip broke and dropped onto the posterior pole. Removal of the broken part was uncomplicated, and the subsequent clinical course was unremarkable. In one case, the handle and branch/tip part were exchanged inadvertently. In the other two cases, neither an exchange nor a maladaptation of the parts was noted. CONCLUSION: An exchange of the hand piece and gripping end may increase the risk of breakage and retinal damage. The delicate gripping tips, however, may break because of inadequate maintenance and/or aging of the material. Intraoperative visual and functional examination is recommended before intraocular use.

Grasping forceps-assisted endoscopic mucosal resection of early gastric cancer with a novel 2-channel prelooped hood.

BACKGROUND: Endoscopic mucosal resection with a cap-fitted panendoscope (EMRC) such as a soft prelooped hood is a useful, effective, and safe technique. One problem with this method is that the lesion cannot always be maintained in the center of the cap because the procedure is performed blindly after aspiration. OBJECTIVE: We developed a 2-channel prelooped hood that facilitates EMRC while simultaneously allowing both grip of the center in the lesion and irrigation of the aspiration site and evaluated the usefulness of this end hood for early gastric cancer. DESIGN: Retrospective study. SETTING: Between August 2003 and October 2004, patients underwent our novel EMR. PATIENTS: Twelve cases of early gastric cancer. INTERVENTIONS: Two side holes were fabricated by drilling in the cap portion of a conventional soft prelooped hood, and then the irrigation tube and the accessory channel tube were glued to the exterior surface of the holes. We placed the fabricated transparent hood at the tip of the endoscope and performed grasping forceps-assisted endoscopic aspiration mucosectomy. MAIN OUTCOME MEASUREMENTS: Accurate aspiration and the rate of en bloc resection. RESULTS: We obtained a satisfactory field of view and accurate aspiration in the center of the tumor in all lesions. The rate of en bloc resection was 91.7% (11/12). LIMITATIONS: Gastric intramucosal cancer. CONCLUSION: Grasping forceps-assisted endoscopic mucosal resection with a novel 2-channel prelooped hood is safe and useful for mucosal resection of intramucosal cancers less than 20 mm and may help center the lesion in the cap before resection.

Unusual implication of biopsy forceps in outbreaks of Pseudomonas aeruginosa infections and pseudo-infections related to bronchoscopy.

Between January and April 2003, a sudden increase in positive respiratory tract specimens for Pseudomonas aeruginosa was observed in an intensive care unit of the University Teaching Hospital of Montpellier, France. Most of the strains were cultured from bronchoalveolar lavage fluid samples, suggesting that bronchoscopic procedures could be implicated. The relationships between isolates were investigated by antibiotyping and pulsed-field gel electrophoresis. Both phenotypic and molecular markers allowed identification of two consecutive nosocomial outbreaks of respiratory infections related to two different bronchoscopes. These two outbreaks implicated nine and seven patients, respectively. Four of these 16 patients had true infections and recovered with antibiotic therapy. Inspection of both bronchoscopes revealed a damaged internal channel caused by defective biopsy forceps. These defects led to improper cleaning and disinfection of the bronchoscopes despite adherence to all current reprocessing procedures. The two outbreaks were controlled after replacing the inner channels of the bronchoscopes and switching from use of re-usable to disposable biopsy forceps. These outbreaks emphasize the need to establish surveillance procedures for detecting contamination of bronchoscopes, and the importance of recording each endoscopic procedure to facilitate further investigations if needed.
