Scientific titleUltrasound guided spermatic cord block for scrotal surgery: a feasibility pilot study
Study objectivesBlindly performed spermatic cord blockade are known to be difficult, painful and has potential risk (intravasal injection of local anaesthesia, perforation of vessels and perforation of the deferent duct). The aim of this study is to test the feasibility of ultrasound guided spermatic cord blockade.
Ethics approval(s)Local ethics committee (Kantonale Ethikkommission KEK) approved on the 10th November 2008 (ref: 167/08)
Health condition(s) or problem(s) studiedRegional anaesthesia
InterventionAfter antiseptic cleaning of the external genitalia, the spermatic cord is grasped gently between the left thumb and index finger. Using a 2 cm pedriatic ultrasound probe the spermatic cord is identified by searching the testicular artery and the deferent duct. Using a 22 G Microlance needle the local anaesthesia (10 ml) is slowly injected around the ductus deferens avoiding vessel perforation.

Patients will then receive either a subcapsular orchiectomy or a vaso-vasostomy.

As of 17/06/2010 the above anticipated end date of this trial has been amended to the actual end date. The initial anticipated end date at the time of registration was 31/12/2009.
Intervention typeProcedure/Surgery
Primary outcome measure(s)

Success rate of the blockade defined as surgery without any substitution (analgesics, conversion to general anaesthesia).

Key secondary outcome measure(s)

1. Visual Analogue Scale (VAS) (0 - 10) during blockade and every 30 minutes after beginning of surgery
2. Volume of local anaesthesia for blockade
3. Duration of blockade: defined as point of time of the first demand of analgesics after surgery
4. Patient satisfaction (scale 0 - 5) in general 1 week after surgery

Completion date01/03/2010
