Hip Fracture Mortality: Is It Affected by Anesthesia Techniques?

Table 1

Characteristics of the study population according to anesthesia type.

Characteristics	GA (𝑛=115)	NB (𝑛=50)	CPNB (𝑛=92)	𝑃 value
Sex (M/F)	40/75	17/33	23/69	0.284
Age	80.6±8.3	77.1±7.8	81±7.4	0.013*
Delay in surgery (Days)	10±9.12	12.1±11.2	8.7±6.2	0.056
Followup (months)	21±17.4	21.9±13.3	17±12.2	0.09
Barthel score	14.4±6.4	14.3±6.9	14.9±5.2	0.887
One-month mortality	22 (19.1%)	4 (8.0%)	16 (17.4%)	0.195
One-year mortality	48 (41.7%)	11 (22%)	26 (28.3%)	0.022**
Overall mortality	80 (69.6%)	18 (36%)	31 (33.7%)	0.001^†
Estimated survival (months)	23.4±1.8	34.6±2.8	31.8±2.6	0.002^‡

* 𝑃<0.05, NB group is significantly younger than the other groups.
** 𝑃<0.05, one-year mortality rate of regional group (NB + CPNB) is significantly reduced compared to GA group.
^†𝑃<0.01, overall mortality rate of regional group (NB + CPNB) is significantly reduced compared to GA group.
^‡𝑃<0.01, estimated mean survival time is significantly higher for regional group (NB + CPNB) than GA group.
GA: general anesthesia, NB: neuraxial block, and CPNB: combined peripheral nerve block.
