Bupivacaína, Ropivacaína e Levobupivacaína em Analgesia e Anestesia de Parto. Repercussões Materno-Fetais

Background and Objectives - Bupivacaine has been a very useful local anesthetic in Obstetrics in spite of its potential cardiotoxicity. In obstetric analgesia, ropivacaine is preferred to bupivacaine, and levobupivacaine is less cardiotoxic than the racemic mixture. The aim of this study was to compare the maternal-fetal effects of bupivacaine, ropivacaine and levobupivacaine in obstetric analgesia and anesthesia. Methods - Participated in this study 33 term pregnant women, physical status ASA I and II submitted to epidural anesthesia who received 18.75 mg (in 15 ml completed with 9% saline) of: GI - bupivacaine, GII - ropivacaine, and GIII - levobupivacaine. Pain intensity, sensory block level, onset time, quality of analgesia, motor block intensity, analgesia duration and time for labor resolution were evaluated. For vaginal delivery, 40 mg (in 8 ml of saline) of the same local anesthetic were used; for cesarean delivery, the dose has been mg in 20 ml solution. Newborns of these mothers were evaluated through the Apgar score in minutes 1, 5 and 10, and through the Amiel-Tison method (neurologic and adaptative capacity score - NACS) at 30 min, 2 h, and 24 h. Results - There were no significant statistical differences among groups as to sensory block level, onset time, quality of analgesia, labor analgesia duration, time for labor resolution, and Apgar scores at minute 1. Ast to motor block, GIII > GII and GI was intermediary. In relation to pain intensity, there was a trend for GI > GIII. For Apgar scores in minute 5, GII > (GI = GIII), and in minute 10 (GI = GII) < GIII. NACS at 2 h showed, GII > GI > GIII, and at 24 h, GII > GIII > GI. Conclusions - Ropivacaine has relieved maternal pain with less motor block. Newborns of GII mothers (ropivacaine) showed the best Apgar and NACS scores.

Efeito da aplicação de prostaglandina (PGF2α) no pós-parto imediato sobre a incidência de retenção de placenta em vacas de leite

The purpose of this study was to evaluate the effect of an intramuscular injection of prostaglandin, within the first hour post partum, on the incidence of retained fetal membranes in cows, at 8 and 12 hours post-partum. Eighty-two cows were used as controls and 82 were treated with 25mg of prostaglandin (LUTALYSE®, 5ml), in two different farms. Cows treated with PGF 2α released the placenta faster (P < 0.10) than cows in the control group (7.72±0.84 vs. 10.07±1.09h). The incidence of retained placenta with more than 8h post partum was 30.5% in the control group and 17.1% in the treated group (P < 0.05), and with more than 12h was 19.5% in the control group and 12.2% in the treated group (P < 0.10). Farm, body condition score and parity showed influence on retained placenta rates, whereas sex of calf and help during calving did not have influence. These data showed that prostaglandin treatment within the first hour post-partum is capable of reduce the incidence of retained placenta and may work as a preventive treatment.

Travessia e impasse: O lugar de Sebastião Uchoa Leite na poesia contemporânea

Sebastião Uchoa Leite's work is circumscribed in a field of tension with tradition, which makes impossible is delimitation to anyone who seeks to draw his poetic profile. The undeniable identification with the modernist masters does not mean the enhancement of such standards; on the contrary, they are contaminated by the crossing of the most diverse references. The ambiguity comes from the fact that the poet neither puts limits in a temporal-spaced territory, nor sets defined directions. His is a hybrid textual project, as in a crossing, which the nomad route places, side by side, the referring speeches from tradition and from the contemporary world.

Efeito do eCG ou benzoato de estradiol associado ao norgestomet na taxa de concepção de vacas de corte submetidas à IATF no pós-parto

This study aimed to compare conception rates at the postpartum period (PPP) in beef cows which were administered either Equine Chorionic Gonadotrophin (eCG) or Estradiol Benzoate (EB) after Norgestomet and submitted to fixed-time artificial insemination (FTAI). The hypothesis was that the administration of eCG or EB enhances the conception rate. Lactating Nelore cows (n=138) and Brangus (n = 63), between 26 and 118 days of post partum period (PPP) were divided into three homogeneous groups, and subdivided in two blocks, inside each group one of them with a PPP d'' 45 days (PPP1; n=107) and another with a PPP > 45 days (PPP2; n=94). All cows received an auricular implant containing 3mg Norgestomet (Crestar®), followed by the administration of 5mg Estradiol Valerate. The auricular implants were kept during 10 days. Cows received 1mL saline solution (n=68, Control Group) or 500IU eCG (Folligon®; n=67; eCG Group) or 1mg Estradiol Benzoate (Index, n=66; EB Group) 24 hours after the removal of the implant. FTAI was made 54 hours after the implant removal. The pregnancy diagnosis was carried through ultrasonography 30 days after FTAI. There was an interaction between treatments and PPP. In the PPP1, the conception rate was higher in the eCG Group than in the EB Group (47.22% vs. 15.38%; Pd''0.01). In the PPP2, the conception rates of the eCG and EB Groups were higher than in the Control Group (41.93%, 44.44% vs. 22.22%: Pd''0.01). It was concluded that in cows up to 45 days of PPP, the eCG associated with Norgestomet enhances the conception rates.

Influência do ciclo lunar no parto: mito ou constatação científica?

Superstitions are found everywhere in our lives, and medicine, a profession that is prides itself on an evidence-based approach to treatment, is not exempt. A superstition that pervades the labor and delivery floor is that it is busier during certain phases of the lunar cycle, specifically the full moon. Although some studies have demonstrated an increase in deliveries that are related to the lunar cycle, there has been disagreement about when, in the lunar cycle, the peak volume occurs. Front to the divergence of the existent results in the literature to relate the events of the lunar cycle with deliveries, the aim of this review was to accomplish the literature in the attempt of explaining this popular culture with base in the results presented by different researchers.

Glicemia, proteinograma e perfil de alguns componentes bioquímicos séricos de cabras da raça bôer no pós-parto

The objective was to test the hypothesis that there is variation of some protein components, biochemical and glucose from the blood of goats in the postpartum period. ElevenBoer goats were used to evaluate the serum following variables: total protein (TP), albumin, α-globulin, β-globulin, γ-globulin, immunoglobulin G (IgG), aspartate (AST), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), creatinine, urea and glucose. These components were determined in moments zero (immediately after delivery), two, seven, 15, 30 and 75 days postpartum. The β-globulin, IgG, creatinine and urea from the goats did not show significant variations, the blood glucose at time zero was greater than the baseline values due to physiological stimulation of glycogenesis determined by the increase of cortisol in delivery. The blood constituents of goats showed variations in the period to 75 days postpartum as a result physiological causes related to delivery and postpartum.

Prevalência de incontinência urinária e disfunção muscular do assoalho pélvico em primíparas dois anos após parto cesárea: Estudo transversal

CONTEXT AND OBJECTIVE: There is uncertainty in the literature regarding the theory that obstetric events and pelvic floor injuries give rise to lower risk of subsequent urinary incontinence among women delivering via cesarean section than among women delivering vaginally. The objective of this study was to assess the two-year postpartum prevalence of urinary incontinence and pelvic floor muscle dysfunction and the factors responsible for them. DESIGN AND SETTING: Cross-sectional study, conducted in a public university. METHODS: 220 women who had undergone elective cesarean section or vaginal childbirth two years earlier were selected. Their urinary incontinence symptoms were investigated, and their pelvic floor muscle dysfunction was assessed using digital palpation and a perineometer. RESULTS: The two-year urinary incontinence prevalences following vaginal childbirth and cesarean section were 17% and 18.9%, respectively. The only risk factor for pelvic floor muscle dysfunction was weight gain during pregnancy. Body mass index less than 25 kg/m2 and normal pelvic floor muscle function protected against urinary incontinence. Gestational urinary incontinence increased the risk of two-year postpartum urinary incontinence. CONCLUSION: Gestational urinary incontinence was a crucial precursor of postpartum urinary incontinence. Weight gain during pregnancy increased the subsequent risk of pelvic floor muscle dysfunction, and elective cesarean section did not prevent urinary incontinence.
