Does virtual reality technology reduce pain and anxiety during outpatient hysteroscopy? A randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of virtual reality technology in reducing pain and anxiety during outpatient hysteroscopy.

DESIGN

A prospective randomised controlled trial.

SETTING

A London University Teaching Hospital.

POPULATION

Women aged 18-70 years undergoing outpatient hysteroscopy procedures.

METHODS

An unblinded randomised controlled trial was performed between March and October 2022 comparing standard outpatient hysteroscopy care with standard care with the addition of a virtual reality headset playing a virtual reality immersive scenario as a distraction technique.

MAIN OUTCOME MEASURES

Pain and anxiety numeric rating scores (NRS) from 0 to 11.

RESULTS

Eighty-three participants were randomly allocated to the control (n = 42) and virtual reality groups (n = 41). The virtual reality group experienced significantly less anxiety during the procedure than the control group (mean NRS 3.29 versus 4.73, mean difference 1.50; 95% confidence interval [CI] 0.12-2.88; P = 0.03). There was no difference in reported average pain (mean NRS 3.73. versus 4.24, mean difference 0.51; 95% CI -1.76 to 0.64; p = 0.41) or maximum pain scores (mean NRS 5.32 versus 5.07, mean difference 0.25; 95% CI -1.05 to 1.55; P = 0.71).

CONCLUSIONS

The use of virtual reality technology as an adjunct to standard care can reduce patient-reported anxiety but not pain during outpatient hysteroscopy procedures. Continued improvements in the technology and the development of increasingly immersive environments may continue to increase the potential to improve the patient experience in this setting.

Risk of vasopressin use: a case of acute pulmonary oedema, post intramyometrial infiltration of vasopressin in laparoscopic myomectomy

A 34-year-old patient underwent a laparoscopic myomectomy, complicated by a profound episode of bradycardia and hypotension following intramyometrial infiltration of vasopressin (20 IU), promptly corrected with intravenous ephedrine (6 mg) and glycopyrrolate (200 µg). At extubation, pink frothy fluid was noted in the endotracheal tube; she was visibly distressed, desaturated to 89% in air and was coughing up pink stained fluid. Acute pulmonary oedema secondary to vasopressin was suspected. A tight-fitting oxygen mask (100%) with positive end expiratory pressure was applied and intravenous furosemide (20 mg) and diamorphine (4 mg, 1 mg increments) were administered to facilitate diuresis and oxygenation. Chest X-ray confirmed acute pulmonary oedema. Arterial blood gas demonstrated type 2 respiratory failure. Over 12 hours, the oxygen was weaned to 1 L/min. She demonstrated excellent diuresis. Troponin and brain-natriuretic peptide were elevated, but echocardiogram was normal. The cardiology diagnosis was vasopressin-induced coronary vasospasm, precipitating acute pulmonary oedema. She was discharged home on day 5.

An unusual cause for epigastric pain in pregnancy. Spontaneous uterine rupture with herniation of the amniotic sac in a 33-week primigravida

A 29-year-old in vitro fertilisation patient presented at 33 weeks of gestation with abdominal pain. An abdominal ultrasound revealed a cystic lesion adjacent to the fundus. During caesarean section, a defect at the fundus was identified with herniation of the amniotic sac through this defect. There were no complications postoperatively and the patient made an unremarkable recovery. With at least one maternal death reported in the most recent confidential enquiry into maternal death, uterine rupture is an obstetric emergency and can have catastrophic outcomes. The incidence of uterine rupture as a result of previous perforation is unclear with little published data and few case reports. Cases of uterine rupture after perforation following hysteroscopic resection of fibroids, uterine septum are well published but the authors found no known previous cases related to laparoscopy. Counselling patients post perforation should include discussion regarding the management of future pregnancies and the risk of uterine rupture.
