The B-Lynch suture technique for postpartum haemorrhage: a decade of experience and outcome.

SUMMARY: Historically, postpartum haemorrhage (PPH) has resulted in mortality and morbidity. Of the three well known messengers of death in obstetric practice, severe postpartum haemorrhage is the most menacing for the midwife and obstetrician. Mumtaz Mahal (1630--Wife of Emperor Shah Jahan) and Princess Charlotte Augusta of Wales (1817) both died from massive PPH. William Smellie, one of the greatest obstetricians, wrote his famous treaty on death resulting from uncontrollable massive postpartum haemorrhage. Improvements over the last 100 years include the introduction of ergometrine and prostaglandin and the invention of the B-Lynch suture and its modifications to improve the conservative management of this life-threatening condition. The B-Lynch surgical technique was first invented in 1997 and it is now timely to review a decade of experience and publications. The rising caesarean section rate and the emergency nature of most PPH remain a constant reminder for the need of effective intervention. A robust protocol is essential (one is being produced by this team) to manage this problem with consensus between obstetricians, anaesthetists, midwives, interventional radiologist and haematologist for prompt and coordinative care in such a life-threatening situation. Modifications of B-Lynch technique were introduced later (Cho et al. 2000; Hayman et al. 2002) and need careful evaluation.

Ten year follow-up of the effect of the B-Lynch uterine compression suture for massive postpartum hemorrhage.

The B-Lynch surgical technique for the management of massive postpartum hemorrhage (PPH) has been used successfully since 1989 in cases where bleeding was secondary to uterine atony with failed conservative management. It allows for conservation of the uterus for subsequent menstrual function and pregnancies. In this report, we present a follow up of a case with successful pregnancy ten years after PPH was managed with the B-Lynch uterine compression suture to demonstrate the long-term anatomical consequences of this operation. This case represents the longest follow up after the application of the B-Lynch suture (brace suture) technique for the control of massive PPH as an alternative to hysterectomy. Published data have confirmed that on the balance of probability, the B-Lynch surgical technique is safe, effective and free of short- and long-term complication.

The B-Lynch and other uterine compression suture techniques.

BACKGROUND: Postpartum hemorrhage (PPH) remains among the 5 main causes of maternal death in developing and developed countries, and uterine atony is the most common cause (75-90%) of primary PPH. Uterine compression sutures running through the full thickness of both uterine walls (posterior as well as anterior) have recently been described for surgical management of atonic PPH. Christopher B-Lynch was the first to highlight this revolutionary principle, and other uterine compression suture techniques have since been described by Hayman and Cho. OBJECTIVES: Step-by-step description of the B-Lynch brace suture and discussion of the current compression suture techniques. CONCLUSIONS: The different uterine suture techniques have proved to be valuable and safe alternatives to hysterectomy in the control of massive PPH, and the present review can make the surgeon better aware of their effective use and the risks they may entail.

A worldwide review of the uses of the uterine compression suture techniques as alternative to hysterectomy in the management of severe post-partum haemorrhage.

Postpartum haemorrhage (PPH) is a worldwide problem. The historical background dates back to William Smelley's in the seventeenth century in his famous treaty of the theory and practice of midwifery in 1752. Changes in clinical factors and surgical expertise compel the modern day midwife and obstetrician to be vigilant in identifying risk factors and apply appropriate solution early. The recent confidential enquiry into maternal death (why mothers die (2000-2002)) identifies areas of substandard care. The rising caesarean section rate adds to the rising incidence of PPH. The reduction in junior doctor's hours may limit the pool of experienced obstetric surgeons available to manage severe PPH competently. There can be major complications following radical surgery for PPH. These include loss of fertility, other morbidity and even maternal death. The invention of the B-Lynch surgical technique for the conservative management of PPH was first performed and reported by a consultant obstetrician and gynaecological surgeon in Milton Keynes NHS Trust publishing the first series of cases in BJOG 1997. This has made a significant impact on the conservative surgical management of massive PPH. There are now over 1300 successful applications of this technique worldwide (CB-Lynch personal communication). Other similar or modified techniques such as Cho's Square Suture and Haymen's modification of the B-Lynch Suture Technique have been introduced adding to more available methods of conservative surgery. The current list of publications of successful application of the B-Lynch compression technique is encouraging and more outcome data can be reported by a letter or e-mail to enquiries@cblynch.com. Obstetricians and midwives both in developed and underdeveloped countries should seek training and attend fire drills in PPH control to avoid maternal morbidity and death. There should be special concentration on effective conservative surgery such as uterine compression techniques to avoid major morbidity and loss of fertility.

The B-Lynch surgical technique for the control of massive postpartum haemorrhage: an alternative to hysterectomy? Five cases reported.

The B-Lynch suturing technique (brace suture) may be particularly useful because of its simplicity of application, life saving potential, relative safety, and its capacity for preserving the uterus and thus fertility. Satisfactory haemostasis can be assessed immediately after application. If it fails, which has not yet been the case, other more radical surgical methods as mentioned in this paper and in the literature can be considered. The special advantage of this innovative technique is an alternative to major surgical procedures to control pelvic arterial pulse pressure or hysterectomy. This suturing technique has been successfully applied with no problems to date and no apparent complications.

A clinical analysis of 500 medico-legal claims evaluating the causes and assessing the potential benefit of alternative dispute resolution.

OBJECTIVE: 1. To evaluate the common causes of medico-legal dispute in obstetrics and gynaecology. 2. To assess the potential benefit of early alternative dispute resolution. DESIGN: A prospective analysis of over 500 cases submitted from over 100 solicitors between 1984 and 1994 for medical expert opinion on potential medico-legal claims. CASES: Five hundred consecutive cases that met the inclusion criteria: 488 from the United Kingdom and 12 from abroad (Hong Kong, Republic of Ireland). MAIN OUTCOME MEASURES: The main principles underlining medico-legal disputes and causes of such claims. RESULTS: Analysis of 500 claims show 46% were misguided allegations, 19% incompetent care, 12% error of judgement, 9% lack of expertise, 7% failure of communication, 6% poor supervision and 1% inadequate staffing. Of the misguided allegations 119/225 cases (59%) were obstetric and 111/275 (40%) cases were gynaecological. The most common cause of obstetric dispute was "cerebral palsy' (22%), while the commonest cause of gynaecological dispute was failed sterilisation (19%). Settled claims were under-reported by solicitors. CONCLUSION: Because of the high percentage (46%) of misguided allegations, an alternative course of dispute resolution must be a realistic way forward. This course of action, combined with improved communication, could result in a major reduction in the costs of potential medical litigation. Early alternative dispute resolution should be considered in an attempt to reduce the escalating quantum of damages and costs. We recommend recruiting independent, experienced and unbiased consultants in active practice within the appropriate specialty to review such cases at the level of hospital complaints management as an in house review procedure, particularly for small and moderate-sized claims, as a means whereby doctors can retain control of medico-legal disputes, in contrast to control by the legal profession.

Alternative positions in the second stage of labour: a randomized controlled trial.

A controlled clinical trial involving 151 primigravidae and 18 midwives assessed the acceptability and outcome of second-stage labour in upright positions. Women who had no specific antenatal preparation and preferences regarding labour positions were managed either conventionally (semi-recumbent and lateral), or encouraged to adopt upright positions (squatting, kneeling, sitting or standing) according to individual preference. Of the women allocated to the upright position 74% completed the second stage upright, with kneeling being the most favoured position, but squatting was, despite all assistance, too difficult to maintain. Adoption of upright positions resulted in a higher rate of intact perineums. There was a clinically apparent reduction of forceps deliveries in the upright group which influenced midwives' attitudes. Moving the parturient from recumbent to upright positions was often perceived to be beneficial when there was slow progress. Estimated blood loss was similar in the two groups, as was the condition of the newborn (Apgar score and umbilical artery pH). Alternative positions in the second stage of labour, in particular kneeling, are achievable even without specific birth aids and antenatal preparation. They appear safe, acceptable to most parturients and their midwives, and are easily integrated into modern labour ward practice; they may have clinical advantages which need further investigation.

Randomised, controlled trial of squatting in the second stage of labour.

A new obstetric aid, the 'Birth Cushion' allows the parturient to sink into a supported squatting posture for the second stage of labour and delivery; it fits onto conventional delivery beds. A prospective, controlled trial of 427 primiparae compared the outcome of labour in women randomly allocated to squatting (218) or conventional semirecumbent (209) management. The squatting group had significantly fewer forceps deliveries (9% vs 16%) and significantly shorter second stages (median length of pushing 31 vs 45 min) than the semirecumbent group. There were fewer perineal tears, but more labial tears, in the squatting group. Apgar scores, blood loss, and post-partum vulvar oedema were similar in both groups. 82% of the women in the squatting group maintained upright positions for most of the second stage, and reported great satisfaction with the supported squatting position. The traditional birth posture of squatting can be easily adapted for modern labour management and has advantages for women in their first labour.
