ABSTRACT
BACKGROUND AND AIM: Pain after surgery continues to be undermanaged. Studies and initiatives aiming to improve the management of postoperative pain are growing; however, most studies focus on inpatients and pain on the first day after surgery. The management of postoperative pain after ambulatory surgery and for several days thereafter is not yet a major focus. One reason is the low return rate of the questionnaires in the ambulatory sector. This article reports the development and feasibility of a web-based electronic data collection system to examine pain and pain-related outcome on predefined postoperative days after ambulatory surgery. MATERIAL AND METHODS: In this prospective pilot study 127 patients scheduled for ambulatory surgery were asked to participate in a survey to evaluate aspects related to pain after ambulatory surgery. The data survey was divided in (1) a preoperative, intraoperative and postoperative part and (2) a postoperative internet-based electronic questionnaire which was sent via e-mail link to the patient on days 1, 3 and 7 after surgery. A software was developed using a PHP-based platform to send e-mails and retrieve the data after web-based entries via a local browser. Feasibility, internet-based hitches and compliance were assessed by an additional telephone call after day 7. RESULTS: A total of 100 patients (50 female) between 18 and 71 years (mean 39.1 ± 12.7 years) were included in the pilot study. Return rates of the electronic questionnaires were 86% (days 3 and 7) and 91% (day 1 after surgery). All 3 electronic questionnaires were answered by 82% of patients. Aspects influencing the return rate of questionnaires were work status but not age, gender, education level and preoperative pain. Telephone interviews were performed with 81 patients and revealed high operability of the internet-based survey without any major problems. CONCLUSION: The user-friendly feasibility and operability of this internet-based electronic data survey system explain the high compliance and return rate of electronic questionnaires by patients at home after ambulatory surgery. This survey tool therefore provides unique opportunities to evaluate and improve postoperative pain management after ambulatory surgery.

The aim of this study was to examine the effect of a 20 degrees Trendelenburg position on the blockade of nerves that exit the brachial plexus proximally in patients undergoing single-injection axillary brachial plexus block. After a pilot study of eight cadavers suggested that a head-down and lateral position would encourage the proximal spread of local anaesthetic, 72 patients undergoing elective surgery were divided into two equal groups: a Supine group and a Modified Position group (lateral position, 20 degrees head-down tilt). Patients were left in the allocated position for 30 min after an axillary block had been performed with alkalinised mepivacaine 1% 49.5 ml. Sensory and motor blockade evaluation showed that there was a significantly higher proportion of axillary nerve (76% vs. 0%, p < 0.001), thoracodorsal nerve (86% vs. 0%, p < 0.001) and subscapular nerve (89% vs. 0%, p < 0.001) blockade in the Modified Position group. Sensory block of the radial nerve was also improved by the modified position (100% vs. 86%, p < 0.05).

We report on a 20-year-old patient with McCune-Albright syndrome suffering from global respiratory insufficiency who required continuous mask ventilation and where intubation had to be avoided. Perivascular axillary anesthesia according to Weber was performed for a double corrective osteotomy of the humerus. During plexus anesthesia the patient was positioned on the non-anesthesized side in a 15 degrees Trendelenburg position. An extension of analgesia was observed up to the complete upper arm region. Using the modified positioning an extension of brachial plexus anesthesia is possible.
