Carpal fractures account for approximately 5% of all fractures and 18 percent of hand fractures, and scaphoid fractures are the most common carpal fracture. Scaphoid fractures account for 10% of all hand fractures and 60-70% of all carpal fractures. Scaphoid fractures are among the most common upper extremity injuries. They frequently occur following a fall onto an outstretched hand. Plain radiographs taken soon after the injury may not reveal a fracture, but the clinician should assume one is present until definitive proof otherwise is obtained.
■ Taiwan: 7% NaHCO3 (e.g. Rolikan) = 16.7 mEq/20 mL/amp.
■ USA: 8.4% NaHCO3 = 50 mEq/50 mL/amp.
■ Usual dose of NaHCO3 = 1 mEq/kg stat followed by 0.5 mEq/kg as needed.
■ 50 mEq of NaHCO3 = 1 amp of 8.4% 50mL = 3 amp of 7% 20mL.
