It is the impression of some surgeons that geriatric horses have a lower survival rate compared to mature nongeriatric horses following colic surgery. One possible reason for this is that geriatric horses may be more critically ill at admission and have more severe disease than mature nongeriatric horses.
To compare admission historical, physical examination and laboratory data for geriatric and mature nongeriatric horses referred for signs of colic.
Medical records of horses admitted with a presenting complaint of colic between 2000 and 2006 were reviewed. Geriatric horses ≥16 years (n = 300) and mature nongeriatric horses 4-15 years (n = 300). Information obtained included duration of colic prior to admission, admission level of pain, heart rate, intestinal borborygmi, packed cell volume (PCV), plasma creatinine and blood lactate concentrations and peritoneal fluid total protein. Data were analysed using a Chi-squared test or an analysis of variance. Level of significance was P<0.05.
There was no difference between geriatric and mature horses in the duration of colic prior to admission or in admission heart rate, PCV, or plasma creatinine or blood lactate concentrations. However, geriatric horses were more likely to be moderately painful and less likely to be bright and alert than mature horses; and less likely to have normal intestinal borborygmi than mature horses. Peritoneal fluid total protein concentration was higher in geriatric than mature horses.
Geriatric horses presenting with signs of colic had a similar admission cardiovascular status based on heart rate, PCV, and plasma creatinine and blood lactate concentration to mature horses. Geriatric horses, however, may have different causes of colic, which may be more serious than mature horses based on pain, lack of intestinal borborygmi and peritoneal fluid total protein concentration.
一些外科医生的印象是，与成熟非老年马相比，老年马在接受疝手术后的存活率较低。造成这种情况的一个可能原因是，老年马在入院时可能病情更危急，并且比成熟非老年马病情更严重。
比较老年和成熟非老年马因疝出现症状而入院时的病史、体格检查和实验室数据。
回顾 2000 年至 2006 年间因疝出现症状而入院的马的病历。老年马（≥16 岁）300 匹，成熟非老年马（4-15 岁）300 匹。获得的信息包括入院前疝的持续时间、入院时的疼痛程度、心率、肠肠鸣音、红细胞压积（PCV）、血浆肌酐和血乳酸浓度以及腹膜液总蛋白。使用卡方检验或方差分析进行数据分析。显著性水平为 P<0.05。
老年马和成熟马在入院前疝的持续时间或入院时的心率、PCV 或血浆肌酐或血乳酸浓度方面没有差异。然而，老年马更有可能表现为中度疼痛，并且不如成熟马机敏和警觉，也不如成熟马具有正常的肠肠鸣音。老年马的腹膜液总蛋白浓度高于成熟马。
表现出疝症状的老年马在入院时的心血管状态与成熟马相似，基于心率、PCV 和血浆肌酐和血乳酸浓度。然而，老年马的疝可能有不同的病因，根据疼痛、缺乏肠肠鸣音和腹膜液总蛋白浓度，可能比成熟马更严重。
