Instrumental 1

The results of this study are in accordance with findings by Crowley [ 36 ] who did not find any reduction in instrumental vaginal births IVB when using a birth chair.

In the present trial the non-significant findings may be compromised by the fact that only half of the women in the experimental group actually gave birth in the allocated position.

In this study the cut off point for bleeding was ml which is in accordance with suggestions from the World Health Organization [ 11 ]. The number of women who had a blood loss between ml and ml was significantly higher in the experimental group.

However, blood loss over ml was not more common in the experimental group than in the control group. Several researchers have found that a blood loss postpartum up to ml may be considered as physiological in a healthy population [ 6 , 9 , 10 , 12 ]. Two studies in a Cochrane systematic review [ 15 ] showed an increased risk for blood loss in excess of ml when birth seats were used [ 13 , 14 ].

The present study confirmed these findings. It was not uncommon for healthy primiparous women in our study to lose more than ml of blood during birth irrespective of birth position and this suggests that loss up to ml can be considered as physiological in a healthy population. The total percentage of women in this study Discrepancies of this kind may be due to difficulties in estimation of blood loss following birth, which is a common problem [ 38 ]. The most accurate means of measuring blood loss is venous blood sampling for determination of hemoglobin concentration; however, such methods have not been broadly adopted because they are neither practical nor affordable in most clinical settings [ 39 ].

In the present study blood loss was measured and weighed which is preferable to a visual estimation. Guidelines for oxytocin injection postpartum have been implemented at the labor wards in the trial and 10 IE oxytocin either IV or IM is recommended for all birthing women immediately after birth. Hemoglobin Hb measurement during pregnancy and the postpartum is recommended according to national Swedish guidelines for antenatal care. Many of the measurements from antenatal visits and during the postpartum were lost to analysis.

However the women who had their Hb levels measured were equally divided between the two groups. It is interesting that there were no statistically significant differences in postpartum Hb despite the findings of a larger blood loss among the participants in the experimental group. A recent review reported a weak correlation between Hb levels three days postpartum and estimations of blood loss during childbirth and concludes that measurement of Hb is not a reliable method to determine blood loss [ 40 ].

However in the present study a postpartum decrease in Hb level in comparisson to antenatal Hb was seen in the whole study population. There was also a general increase in postpartum Hb level weeks postpartum regardless of group allocation. A Cochrane systematic review [ 15 ] included two studies that showed that birth on a birth seat increased the occurrence of second-degree tears [ 14 , 41 ].

This finding was not confirmed in the present study; we found no increase in perineal lacerations, anal sphincter tears AST or perineal edema in the experimental group. The CAPS Childbirth and Pelvic Symptoms study prospective multicenter study discussed risk factors associated with the occurrence of AST including instrumental vaginal birth, birth weight and length of the second stage of labor [ 42 ].

Gottvall et al. They reported that semi-recumbent position with legs in stirrups Other researchers have indicated instrumental vaginal birth as a prominent factor [ 27 , 43 ].

Another risk factor for AST is infant weight over g. The size of the child may have greater impact on the occurrence of AST than the particular birthing position. It has been argued that episiotomies at childbirth should be individualised and restricted [ 44 — 46 ]. Nulliparous women undergoing episiotomy have an increased risk for spontaneous obstetric laceration in subsequent births [ 46 ].

According to Webb and Culhane [ 47 ] some hospitals still perform routine episiotomies in nulliparous women. This study has several limitations. At labor ward two the time span between consent for participation and randomization was rather long and Hundley and Cheyne suggest that this situation may result in large losses of eligible women to intrapartal studies [ 48 ].

Another limitation is that of non-compliance with allocated intervention. This may well affect the results, which should be interpreted with caution. According to Hundley and Cheyne [ 48 ] levels of non-compliance tend to be high in intrapartal studies and in this trial non-compliance could be explained to some extent by women who regreted giving their consent to participate, or possibly used the birth seat for a very short time period and then gave birth in another position.

Medical considerations such as prolonged labor or suspected fetal compromise can also cause non-compliance. Yet another explanation could be that midwives preferred not to comply with the intervention allocation.

Reasons for non-compliance in this study will be further investigated in a new study. Problems with missing data for the primary outcome variable are not uncommon, nevertheless it is considered important to base conclusions on the results of analysis by intention to treat [ 49 ]. The fact that some women included in the study met exclusion criteria may also be a potential limitation. A total of 19 women with a BMI above 30 were erroneously invited to join the study but the analysis by intention to treat required inclusion of them in the analysis.

A further 22 women were included despite the fact that gestational age should have excluded them. Since these women were equally divided between groups, we consider that these factors have not affected the overall results. Three women in the control group were randomized before a diagnosis of breech presentation. All three gave birth vaginally. Earlier research [ 15 ] failed to provide guidelines for the level of reduction in vaginal instrumental births that might be expected.

The study was insufficiently powered to detect a small difference between the groups, should this have occurred. However, even studies that have insufficient power can contribute valuable data to meta-analyses in order to answer important questions. The analysis by intention to treat maintains the advantages of random allocation [ 50 ]. Hollis and Campbell [ 49 ] argue that the effect of an intervention in this case birth on a birthing seat can best be assessed by comparing participants according to the intention to treat rather than according to the actual intervention received.

Analysis by ITT also shows how an intervention works in a clinical setting [ 51 ]. However, the complex process of childbirth which involves so many aspects of human behaviour and interaction may render it difficult to assess the effects of a particular intervention, in this case, a birth seat, and to reach consensus on its use. Interactions between research participants and professionals involved in the recruitment in trials are also of vital importance [ 48 ] and in this trial a large number of eligible nulliparous women were never asked to give consent.

Continued professional education for midwives in Sweden, might help to increase awareness of the need to provide evidence based care and hence, adherence to trial protocols may be improved. The study showed an increased blood loss between ml and ml for the birth seat group but no increase in blood loss over ml.

Giving birth on a birth seat had no adverse consequences for perineal outcomes and may be protective against episiotomies. The growth of totalitarianism is also directly associated with the extinction of critical thought and with positivistic philosophies which overestimate the importance of instrumental action. From the Cambridge English Corpus.

Suggesting that the contingencies of nature are rationally domesticated by technological objectivity, empiricism reduces knowledge to power, reason to instrumental reason. These examples are from the Cambridge English Corpus and from sources on the web. Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors.

Hence, both hold that political questions are questions of ends, requiring a purpose-assigning judgment, whereas technology involves questions of means, requiring only instrumental reason.

The main part of the paper examines the stimulus conditions which appear to control the acquisition of instrumental knowledge. Does non- instrumental justification relax the conditions under which consent to authority is binding? Focusing upon the roll of instrumental considerations in family support thus helps us to uncover elements of the morality of duty in family life. Explanations for these apparently contradictory tendencies will not be found by taking an instrumental approach to family law.

In instrumental terms there is much to be said for the informal approach. In fulfilling these aims, specific use of the potential of different aspects of language and of literacy has been instrumental. His analysis of the development of instrumental reason, however, was as a consequence of the development of the forces of production. The point in case seems to be an instrumental use of history. The link between research and design could then be identified as an instrumental one, with the former directly guiding the latter along prescriptive tramlines.

They reported that semi-recumbent position with legs in stirrups (%) and squatting position (%) resulted in a statistically significant increased risk for AST. Other researchers have indicated instrumental vaginal birth as a prominent factor [27, 43]. In our trial 30% of the ASTs in the total study population were due to instrumental.
