Disease relevance of Anesthesia, Obstetrical

• Analysis of maternal and neonatal blood samples for cholinesterase-activity determination revealed a case of hypoventilation in the newborn to be apparently secondary to succinylcholine administration to the mother during obstetric anesthesia [1].
• The patients underwent hysteroscopy and endometrial biopsy with paracervical block by 10 mL of 1% mepivacaine hydrochloride solution (n = 87) or no local anesthesia (n = 90) and assessed lower abdominal and pelvic pain according to a 10-point linear analog scale [2].
• There have been many reports of lidocaine toxicity especially after maternal paracervical block anesthesia [3].
• Thrombocytopenia, low molecular weight heparin, and obstetric anesthesia [4].

High impact information on Anesthesia, Obstetrical

• Paracervical block with low doses of chloroprocaine. Fetal and maternal effects [5].
• Results of 261 paracervical blocks done with a dose of 12 ml of 1% chloroprocaine hydrochloride solution containing 1:200,000 epinephrine were recorded [5].
• Obstetric anesthesia for a quadriplegic patient with autonomic hyperreflexia [6].
• Milk of magnesia is an effective preinduction antacid in obstetric anesthesia [7].
• Low doses of lignocaine can, however, be recommended in paracervical block (PCB) as well as EA without pre-medication [8].

Biological context of Anesthesia, Obstetrical

• This prospective study assessed the role and compared two techniques of paracervical block (PCB) for pain relief during suction evacuation for first-trimester termination of pregnancy following cervical priming with misoprostol [9].

Anatomical context of Anesthesia, Obstetrical

• METHODS: A parallel-group randomized trial of adjunctive lidocaine vaginal gel versus adjunctive lidocaine paracervical block (with sedation for both groups) was performed in participants undergoing oocyte retrieval [10].
• By using pulsed color Doppler ultrasound techniques the pulsatility indices were measured from both uterine and umbilical arteries before, one minute and 20 minutes after a paracervical block with bupivacaine [11].
• The use of PGE2 gel in subjects where there appears to be marked cervical resistance at the level of the internal os probably allows safer introduction of the IUD using less force than after using analgesia to the cervix alone or a paracervical block [12].

Associations of Anesthesia, Obstetrical with chemical compounds

• A double-blind, randomized study comparing CP to lidocaine when used for paracervical block was carried out [13].
• While choice of method and agent must be individualized, continuous lumbar epidural block with bupivacaine appears as effective as and less often dangerous to the fetus than paracervical block [14].
• CONCLUSION: Mepivacaine paracervical block remains an anesthetic option in low-risk patients [15].
• Intrathecal meperidine and shivering in obstetric anesthesia [16].
• Use of cimetidine as an oral antacid in obstetric anesthesia [17].

Gene context of Anesthesia, Obstetrical

• A prospective, randomized, double-blind and placebo-controlled study to assess the efficacy of paracervical block in the pain relief during egg collection in IVF [18].
• The H2-receptor antagonist, cimetidine, was used instead of magnesium trisilicate BPC as routine antacid therapy before both elective and emergency obstetric anesthesia [17].
• Obstetric anesthesia and systemic lupus erythematosus [19].
• BACKGROUND: Acid aspiration syndrome is still an important cause which contributes to maternal mortality in obstetric anesthesia [20].

Analytical, diagnostic and therapeutic context of Anesthesia, Obstetrical

• All patients received premedication with 600 mg of ibuprofen and a paracervical block with 1% lidocaine without epinephrine [21].
• Eleven women had no analgesia, 24 women received 75-100 mg pethidine intramuscularly, 12 epidural analgesia with 0.25% bupivacaine and three paracervical block with 0.125% bupivacaine [22].
• Effective obstetric paracervical block with reduced dose of bupivacaine. A prospective randomized double-blind study comparing 25 mg (0.25%) and 12.5 mg (0.125%) of bupivacaine [23].
• Double-blind randomized comparison of xylocaine and saline in paracervical block for diagnostic fractional curettage [24].
• The aim of this prospective trial was to evaluate and compare paracervical block with diclofenac for pain relief during manual vacuum aspiration (MVA) for surgical termination of pregnancy [25].
