“…One study was reported in a brief conference abstract; we made several attempts to contact the study author without success (Anonymous 1995). Finally, two studies which were included in earlier versions of this review (Chia 1990; Tawfik 1982) have been excluded from this update. The reason for these additional exclusions is because this review is one in a series of Cochrane reviews which contribute to an overview of systematic reviews of pain relief for women in labour (Jones 2011b) and share a generic protocol (Jones 2011a).…”

“…We did not anticipate that there would be any cross-over trials for an intervention carried out during labour, however, one such trial was identified (Chia 1990) but we excluded it for other reasons. In updates of the review, if further cross-over trials are identified which are otherwise eligible for inclusion, we will only include data from the first stage of such studies to avoid the risk of bias associated with treatment order effect.…”

Background-Transcutaneous nerve stimulation (TENS) has been proposed as a means of reducing pain in labour. The TENS unit emits low-voltage electrical impulses which vary in frequency and intensity. During labour, TENS electrodes are generally placed on the lower back, although TENS may be used to stimulate acupuncture points or other parts of the body. The physiological mechanisms whereby TENS relieves pain are uncertain. TENS machines are frequently operated by women, which may increase a sense of control in labour.

“…Through the stimulation of these nerves, the mechanism is activated before reaching the brain, blocking or altering nociceptive impulses originating from the spinal cord 27,28 . Although there are reports in the literature that TENS may be applied at any moment during labor, including some studies indicating that its effectiveness would be better in the initial phases of the first stage 12,27,29 , this could not be evaluated directly due to a lack of standardization at the beginning of the procedure.…”

“…Pain intensity and analgesic effects can only be judged by the person who is suffering. The mother's perception of pain during labor depends on the intensity and duration of contractions, the speed with which the cervix dilates, woman's physical and emotional condition, previous experience, present expectations and cultural factors 29,32 . Therefore, the best way of assessing the perception of pain should be the parturient's report.…”

Background: Transcutaneous electrical stimulation (TENS) is a non-pharmacological pain relief method. It is an auxiliary method and not intended to replace other techniques. Objectives: To perform a systematic review assessing the effectiveness of TENS compared to no TENS treatment or placebo with the following outcomes: pain relief (primary outcome), analgesic requirements, duration of labor, the mother's satisfaction, type of delivery and fetal repercussions (secondary outcomes). Methods: The Pubmed, LILACS and Scielo databases were searched for randomized controlled trials and quasi-randomized trials published between 1966 and 2008 using the keywords 'TENS', 'Labor', 'Labor pain' and 'obstetric labor'. The selection of eligible items and assessment of methodological quality were performed independently by two researchers. Random effects meta-analysis was performed for studies that were sufficiently homogeneous. Results: Nine studies involving a total of 1076 pregnant women were included. There was no statistically significant difference between groups in pain relief during labor (pooled RR = 1.09, 95% CI = 0.72 to 1.65) or the need of additional analgesia (pooled RR = 0.89, 95% CI = 0.74 to 1.08). There was no evidence that TENS interfered in any of the outcomes except the mothers' desire to use TENS in future deliveries. Conclusions: The use of TENS had no impact on mother or child and no influence on labor.According to the results of this review, there is no evidence that TENS reduces the use of additional analgesia.Keywords: Transcutaneous Electrical Nerve stimulation; labor pain; obstetric analgesia; labor, obstetric. ResumoContextualização: A estimulação elétrica transcutânea (EET) é um método não farmacológico utilizado no alívio da dor do trabalho de parto. Sua aplicação representa um método adjuvante que não se propõe a substituir outras técnicas. Objetivos: Desenvolver uma revisão sistemática para avaliar a eficácia da EET comparada à ausência de EET ou placebo, segundo os desfechos: alívio da dor do trabalho de parto (desfecho primário), uso de analgesia complementar, duração do trabalho de parto, satisfação da parturiente, tipo de parto e repercussões fetais (desfechos secundários). Métodos: Realizou-se uma busca sistemática nas bases de dados PubMed, LILACS e SCIELO por ensaios clínicos randomizados e quasi-randomizados, publicados entre 1966 e 2008. As palavras-chave utilizadas foram 'TENS', 'labor', 'labor pain' e 'labor obstetric'. A seleção de artigos elegíveis e a avaliação de sua qualidade metodológica foram feitas independentemente por dois revisores. Meta-análises de efeitos randômicos foram realizadas quando estudos que investigavam um mesmo desfecho eram suficientemente homogêneos. Resultados: Nove estudos, incluindo 1076 gestantes, foram selecionados. Não houve diferença significativa entre os grupos no alívio da dor do parto (pooled RR=1,09; 95%IC=0,72-1,65) ou na necessidade de analgesia complementar (pooled RR=0,89; 95%IC=0,74-1,08). Não se observou evidência da interferência...

“…This is consistent with the previous studies. [9][10][11][12][13] Bitsch et al compared Tramadol with pethedin in labour analgesia and found identical analgesic efficiency in both the group. 14 Jain et al compared analgesic efficacy of intramuscular opioids: meperidine and tramadol with epidural analgesia.…”

INTRODUCTIONGiving birth is a painful process. Any intervention that leads to improvement in pain relief is worthy of investigation 1 . Opioid as well as epidural analgesia is effective means for pain relief in labour, notwithstanding their shortcomings. Data regarding Entonox (50% Nitrous Oxide and 50% Oxygen mixture) for labour analgesia is not available in current Indian literature. Use of Entonox offers many apparent advantages over the ABSTRACT Background:Childbirth is an emotion-filled event and the mother needs to bond with her newborn baby as early as possible. Any intervention that leads to improvement in pain relief is worthy of investigation. Entonox, opioids as well as epidural analgesia are effective means for pain relief in labour, notwithstanding their shortcomings. The objectives of study are to compare the effectiveness of intermittent inhalational Entonox for labour analgesia with intramuscular opioid (Tramadol) and to compare the effects of Entonox and Tramadol as labour analgesia on the maternal and fetal outcome of labour. Methods:The study was a prospective randomized, comparative study of two established techniques of labour analgesia. The study was carried out in 100 subjects. These subjects are divided into two groups. Group A -Tramadol Group: 50 women in active labour who received 100 mg tramadol intramuscularly with repeat dose of 50mg tramadol 4 hourly. Group B -Entonox Group: 50 women in active labour who received entonox for labour analgesia. Results:The mean VAS (visual analogue score) i.e. the pain score in group I (Tramadol) was 4.58±1.54 and Group II (Entonox) was 4.02±1.99 which is significantly low when compared to Group I (Tramadol) p<0.001. Study also showed that both the analgesics Entonox as well as Tramadol does not cause any significant change when compared for duration of labor. The rate of instrumental assisted vaginal deliveries and normal vaginal deliveries were almost equal in both the groups. In our study, the mean overall satisfaction level of the parturients in group II (Entonox) at 1 hr post delivery was (5.06±1.42) and 24 hr post delivery was (6.64±1.66) which was more when compared with tramadol group. The difference was statistically significant (p value was <0.001). This indicates that overall satisfaction level of the parturients is more with the use of Entonox when compared with Tramadol. Conclusions: Therefore, it is concluded that intermittent inhalational Entonox provides better labour analgesia then intramuscular opioid Tramadol.
