    Prospective study on ocular motility limitation due to orbital muscle entrapment or impingement associated with orbital wall fracture2017In: Injury, ISSN 0020-1383, E-ISSN 1879-0267, Vol. 48, no 7, 1408-1416 p., S0020-1383(17)30268-1Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: The recommended urgent surgical management of ocular motility restriction due to orbital muscle entrapment or impingement associated with orbital wall fracture needs to be elucidated.

    AIM: To evaluate the importance of the time from injury to surgery for the outcome in ocular motility and diplopia, the time lapse of ocular motility, diplopia and hypesthesia recovery.

    MATERIAL AND METHODS: Patients with entrapment or impingement of orbital contents due to orbital wall fracture were followed up prospectively over 1year regarding ocular motility, diplopia, hypesthesia and cosmetic deformity.

    RESULTS: 21 patients (10 entrapments and 11 impingements) were included and treated surgically. The median time from injury to surgery was 36 (8-413)h for the entrapment group and 168 (48-326)h for the impingement group. The median time from study inclusion to surgery was 0 (0-1) days for the entrapment group and 1.0 (0.2-4.8) days for the impingement group. All the patients had ocular motility limitation and diplopia at the inclusion. Ocular motility improved gradually and was normal at final visit. Diplopia resolved gradually in all patients except in two with non-disturbing diplopia, at the final visit. Forced duction test was positive in 90% of the patients in the entrapment group and 70% in impingement group. At final visit, hypesthesia was found in none of the patients in the entrapment group but in 4 patients in the impingement group.

    CONCLUSIONS: In this, the first prospective long term follow up of orbital wall fractures with ocular motility restriction, we did not find any significant correlation between the time from injury to surgery and the outcomes in ocular motility and diplopia. An entrapment requires surgery as soon as possible; however, the surgical reduction is at least as important as surgical timing. Surgery should be delayed until it can be performed by an experienced surgeon. Ocular motility restriction causing diplopia due to impingement is not an ophthalmologic emergency and surgery is recommended if the diplopia and ocular motility has not improved over time. Clinical examination of ocular motility and not CT scan findings is crucial to determine whether a limitation of ocular motility exists or not.

    Normal gastric emptying time of a carbohydrate-rich drink in elderly patients with acute hip fracture: a pilot study2017In: BMC Anesthesiology, ISSN 1471-2253, E-ISSN 1471-2253, Vol. 17, no 1, 23- p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Guidelines for fasting in elderly patients with acute hip fracture are the same as for other trauma patients, and longer than for elective patients. The reason is assumed stress-induced delayed gastric emptying with possible risk of pulmonary aspiration. Prolonged fasting in elderly patients may have serious negative metabolic consequences. The aim of our study was to investigate whether the preoperative gastric emptying was delayed in elderly women scheduled for surgery due to acute hip fracture.

    METHODS: In a prospective study gastric emptying of 400 ml 12.6% carbohydrate rich drink was investigated in nine elderly women, age 77-97, with acute hip fracture. The emptying time was assessed by the paracetamol absorption technique, and lag phase and gastric half-emptying time was compared with two gender-matched reference groups: ten elective hip replacement patients, age 45-71 and ten healthy volunteers, age 28-55.

    RESULTS: The mean gastric half-emptying time in the elderly study group was 53 ± 5 (39-82) minutes with an expected gastric emptying profile. The reference groups had a mean half-emptying time of 58 ± 4 (41-106) and 59 ± 5 (33-72) minutes, indicating normal gastric emptying time in elderly with hip fracture.

    CONCLUSION: This pilot study in women with an acute hip fracture shows no evidence of delayed gastric emptying after an orally taken carbohydrate-rich beverage during the pre-operative fasting period. This implies no increased risk of pulmonary aspiration in these patients. Therefore, we advocate oral pre-operative management with carbohydrate-rich beverage in order to mitigate fasting-induced additive stress in the elderly with hip fracture.
