Randomized Controlled Trial
Comparison of lidocaine spray and paracervical block application for pain relief during first-trimester surgical abortion: A randomised, double-blind, placebo-controlled trial.
Surgical abortion is one of the most frequently performed gynaecological procedures and its associated pain has always been a problem in gynaecology. Here we studied the analgesic efficacy of lidocaine spray and paracervical block (PCB) in patients undergoing first-trimester surgical abortion. A randomised double-blind placebo-controlled study was conducted on 108 women requesting pregnancy termination. ⋯ The median VAS scores during procedure in placebo, lidocaine spray, PCB plus lidocaine spray and PCB groups were 8 (7-9), 5 (4-8), 4 (3-4) and 5 (3-5), respectively. The most effective method of pain relief during first-trimester abortion can be achieved through a combined use of PCB plus lidocaine spray. Therefore, lidocaine spray is a non-invasive complementary anaesthetic method versus traditional PCB for first-trimester surgical abortion.

Randomized Controlled Trial
Effect of lidocaine spray in pain management during office-based endometrial sampling: A randomised placebo-controlled trial.
Office-based endometrial sampling is the most frequently performed gynaecological procedure. The procedure is usually associated with pain and discomfort. Several anaesthetic and analgesic techniques (e.g., non-steroidal anti-inflammatory drugs, paracervical block, misoprostol and topical anaesthetics) are used for pain management during endometrial sampling. ⋯ The mean pain score during procedure was 3.51 ± 1.51 in the lidocaine spray group and 5.11 ± 1.66 in the placebo group. Lidocaine spray treatment significantly lowered the pain scores compared with placebo (p < 0.001). Lidocaine spray can be accepted as a non-invasive, easy to apply and more comfortable anaesthetic method for office-based endometrial sampling.

Randomized Controlled Trial
Evaluation of pain during hysterosalpingography with the use of balloon catheter vs metal cannula.
Our aim was to investigate the use of a balloon catheter device in comparison with metal cannula for hysterosalpingography (HSG) in terms of patient comfort. A total of 168 patients were randomised for HSG either with a balloon catheter (n = 83) or metal cannula (n = 85). ⋯ The reinsertion rate of metal cannula was higher (8.2% vs 2.4%) as well as the incidence of nausea being the most common short-term adverse effect (14.1% vs 1.2%) in the metal cannula group (p = 0.002). Performing HSG with a balloon catheter is advantageous for decreasing the pain and side-effects related to the procedure, when compared with the use of a metal cannula.

Observational Study
Effect of postural changes on inferior vena cava dimensions and its influence on haemodynamics during caesarean section under spinal anaesthesia.
The effect of postural changes on inferior vena cava (IVC) dimensions and its influence on intra-operative haemodynamics in term parturients can be studied using abdominal ultrasound by a subcostal approach. Thirty-two term parturients scheduled to undergo elective caesarean section under spinal anaesthesia were recruited in this observational study. ⋯ A greater fall in systolic blood pressure (>20%) was noted in patients with collapsibility index of more than 11.5 in recumbent with wedge position with a positive predictive value of 86%. IVC dimensions change significantly with change in position and collapsibility index in recumbent position can be a useful parameter for predicting hypotension during caesarean section under spinal anaesthesia.
